Ferocious 545hp supercharged and 715hp turbocharged carbon-clad E46 M3s tamed by one owner. Decisions are hard, especially when it comes to choosing between a supercharged E46 M3 and a turbocharged E46 M3, so why not just have both…? Words: Elizabeth de Latour. Photos: Andrew Thompson.
545hp supercharged and 715hp turbo E46 M3s
Decisions are never easy to make, especially when you’re faced with two equally appealing options. Chinese or Indian, for example, or cookies and brownies, or pizza and, well actually there’s no alternative option to pizza because pizza just always wins. Sometimes, you don’t even have to decide, like with cronuts, or a turducken, just have everything, because more of everything is always better. For example, why choose between a supercharged E46 M3 and a turbocharged E46 M3, when you could have both? That is exactly what Jaime Taylor did and we’d like to think that decision made his life immeasurably better in every way.
This man is a serial car buyer and modifier with a car history varied enough to make your head spin, including a midengined, RWD Peugeot 205 GTi and a Sierra Cosworth, a scattering of BMs and some serious big-power builds, such as a 511hp Skyline R34 GTR, a 670hp Skyline R32 GTR and a 513hp Audi RS4. Jaime is no stranger to going fast and is clearly hopelessly addicted and devoted to the modifying lifestyle, which makes him our kind of guy, and we guess answers the question: “What sort of person owns a pair of cars like this?”
What’s really interesting here is that this is really a tale of two parallel builds, which were happening alongside each other at virtually the same time. Spooky. We’ve got Jaime, who wanted to build a turbo E46 M3 but ended up going down the supercharged route, and Andy Bennett, who bought the turbocharged car and proceeded to put a huge amount of effort into getting it running as it should, then ended up selling it to Jaime, who’d actually wanted to buy it all along but was beaten to the punch by Andy all those years previously. It’s a twisting tale deserving of its own movie adaptation, so grab some popcorn, get comfy and we’ll begin.
When Jaime bought his M3 in 2014, it already had a long list of tasty bits on it, including carbon front wings and carbon bonnet, a roll-cage, BBK, CSL air box and Recaro RS seats but even better than that it had been fitted with a new engine from BMW and had covered less than 20,000 miles on it. “The new engine was a blank canvas to work on,” smiles Jaime. “At the time I didn’t know any UK company who could turbocharge the S54 but did know a company in the States. We were talking about shipping the car over there to get the job done, but it would have been gone for six months for all the new fabrication work to be done because they hadn’t done a right hand drive vehicle before,” he explains. “In the end, with a new car on the drive, we decided to go down the supercharged route so then the car could stay local,” and that’s a pretty sensible decision as the job could be done much more quickly and he’d have more time to actually enjoy the car.
The supercharger kit comes from VF Engineering, with Jaime opting for VF570 flavour, the company’s most powerful E46 M3 supercharger offering. At its core is a Vortech V3-Si supercharger, capable of running at 26psi and rated for 775hp, so producing the 570hp and 380lb ft that VF Engineering claims for this kit is a walk in the park. The kit also boasts a cast manifold with a slide-in air/water intercooler cartridge and is a serious setup, able to deliver a huge hike in power. Initially, though, that wasn’t the case, as once Jaime had got the car back from being mapped and stuck it on a dyno he found it was only making 499hp.
“On each of the five back-to-back dyno runs we did the power was going down about 20hp every time because of heat soak,” he explains. “The engine was pulling the timing and it couldn’t make the power. To fi x this we got Gary Adlington, who runs Eastwood Garage in Falmouth, to fit an AEM direct port methanol kit from the States. Gary is a genius,” enthuses Jaime, “he put a Cosworth engine in a boat and some other crazy stuff – incredible character and he also worked on Andy’s engine.” Yes, in a further coincidence, both Jaime and Adam used Gary’s services for their respective projects; it’s like fate brought everything together. With the meth injection kit on board it was time to head back to the dyno and this time the numbers didn’t disappoint. “On the first run it made 513hp, 530hp on the second and we finished with 545hp,” grins Jaime and that grin is fully justified as that’s a serious power figure. Of course, running monster power means you need plenty of supporting mods and this S54 has been treated to a Mishimoto electric fan coupled to a larger Mishimoto rad, a 55ºC thermostat, the secondary air pump has been removed along with the air con and it’s all finished off with set of sport cats and a Milltek rear exhaust section.
Handily, the previous owner had done a lot of the groundwork on the chassis meaning the M3 was already in a good position to be supercharged, but Jaime has been upgrading things along the way over the past two-and-a-half years to make sure the car was the best it could be. The chassis has been enhanced with a set of KW V3 coilovers and is joined by Turner Motorsport top mounts and adjustable Turner anti-roll bars both front and rear. In addition to this there are adjustable rear camber arms, poly bushes fitted throughout and there’s also a 4.10 ratio rear diff. The brakes are seriously beefy and more than up to the task of slowing this powerhouse of an M3; up front there’s an Alcon BBK comprising 365mm discs, utilising Reyland brake bells, clamped by red six-piston calipers and braided hoses and Pagid RS-29 pads have been fitted allround while 710 racing brake fluid tops off the brake upgrades. When it came to choosing wheels, Jaime wanted something light and good-looking that would suit his track-orientated build. “Apex wheels were the weapon of choice,” he says, “they’re lightweight, concave and when I was searching for M3 track cars online everyone was running them so they were clearly the wheels to go for.” He’s gone for the Arc- 8, which looks great on the E46, and he’s running a square setup with 10x18s all-round wrapped in sticky Federal 595RS-R tyres.
No doubt a big part of the appeal of this M3 when Jaime was shopping was the fact that it looked so flipping fantastic, with the carbon bonnet, wings and boot lid really giving it a full-on track look and over the time he’s had the car he’s built on that, giving it an even more extreme appearance. “It was actually booked in to have all the carbon painted,” admits Jaime, “but I ended up going against it and kept the carbon on show for an aggressive track look,” and we’re glad he did. The car also wears a carbon front splitter and canards, plus Jaime has carried out a front foglight delete, and added a carbon rear diffuser, all of which combine to really make this M3 stand out and it’s got a lot of presence.
The interior had already been stripped out and caged-up when Jaime bought the car, but here too there was room for improvement and it all started with the seats. “On the first track day I took the car to I realised the seats were too high as we kept hitting our heads on the roof,” he explains. So out came the Recaro RS seats and in went in a pair of Corbeau Club Sport buckets, and Jaime was now far more comfortable and able to actually enjoy driving his M3. Other interior changes include the aforementioned roll-cage, a Safety Devices bolt-in item, an alcantarawrapped wheel from Royal Steering Wheels, full carbon door cards with red door pulls, an AEM hand controller for the methanol injection, a lightweight battery, fire extinguishers and a carbon blanking plate that covers the hole where the sat nav screen once sat. We love the fact that while it is stripped out and most definitely hardcore, it’s been finished to an incredibly high standard with some very high quality materials, and it all combines to make it even more special.
While Jaime was busy getting stuck into his supercharged E46 M3 project, Andy was well underway with getting his turbo E46 M3 up to scratch. Back in late 2013, having just sold a supercharged Range Rover Sport, Andy was flush with cash and looking to buy a second home to rent out. At least that was the sensible, grown-up plan, but one brief eBay session later it had all gone to pot as he’d spotted a turbo E46 M3, this very car, up for sale and, deciding that he couldn’t not buy it, he snapped it up with a sneaky bid in the final few seconds of the auction, unknowingly swiping it away from Jaime.
Not only did the car have a claimed 650hp, but it had also been on the cover of the March 2008 of PBMW, and came with a vented carbon bonnet, carbon bootlid, BBK and ticked just about every box that there was to be ticked. Quickly, however, it transpired that the car was not in rude health, making only 465hp on the dyno, not the figure Andy had been led to believe, as well as suffering from numerous issues to do with the turbo conversion. It was not a happy car. It was decided that a new intake manifold and stand alone ECU were needed, so Andy took the M3 off the road and put it into storage while he saved money for the work it needed. It was at this time that he learned about the infamous E46 subframe failure issue and, after inspecting the state of his M3, he discovered that, lo and behold, the subframe was not in a good way...
While we can’t imagine his mood was particularly good at this point, Andy had a turbocharged M3 and he was determined to make it the best turbocharged M3 he could; where Jaime started his project with a clean slate, Andy had the perfect opportunity to not just fix what was wrong with his M3, but improve everything as he went along, and he’s definitely done that and then some.
Before he could even think about getting the engine running at full capacity, that rear end needed sorting out so the old boot floor was cut out, a new one was welded-in and Redish Motorsport reinforcement plates were installed, along with a box section welded across the boot floor to eliminate any flex. At the same time, the whole back end was poly bushed and the propshaft rubber donut was replaced by an uprated Revshift polyurethane set up. The poly bushing extends throughout the chassis now and the suspension has been thoroughly upgraded throughout to ensure it’s up to the task of coping with a turbocharged S54 above. Naturally the car sits on coilovers but they’re not the usual suspects, this M3 having been fitted with Tein items complete with electronic damping adjustment, and these are joined by adjustable front camber plates and Eibach anti-roll bars front and rear and there’s also a Strong Strut front brace with a Schnitzer item mounted at the back. A Brembo GT BBK takes care of stopping duties, with six-pot calipers and monster 380mm discs up front and 345mm discs at the rear, the red calipers contrasting perfectly against the black spokes of the 19” CSL replicas, themselves fitted with Toyo R888 tyres for maximum grip and traction. When it came to the engine Andy admits that, without the help and knowledge of Gary Adlington, he probably would have given up on the car a long time ago, which would have been a shame as he would not have had the chance to experience the fury of a fully operational turbo M3. The main components required to get the S54 performing as it should were an AEM Infinity 8 ECU, Horsepower Freaks intake manifold and boost pipe, a pair of HKS SSQV4 blow-off valves and an AEM water/meth injection kit. The intercooler was also sent off to have the end tanks cut off and new ones made from thicker aluminium welded on. The final engine spec makes for some eye-widening reading as some serious work has gone into making this S54 as powerful as it is. The turbo kit itself comes from Savspeed Racing and uses a Turbonetics T70 turbo and the engine has been bolstered with a set of Wiseco low compression pistons, Pauter con rods, VAC Motorsports head bolts and a steel-lined head gasket while twin fuel pumps feed 750cc injectors via an Aeromotive fuel filter. The result of all that is pretty spectacular, with four different power maps to choose from: the mildest map offers a sensible 500hp, which we imagine is handy for popping to the shops for a pint of milk, while the wildest map delivers 715hp, which you’d probably use for getting a pint of milk and some toilet paper. Perhaps a cheeky Snickers as well. A Clutch Masters twin-plate paddle clutch has been added to cope with all that newfound power and there’s also a short-shift kit rounding things off.
As with the supercharged car, this turbo M3 is a riot of carbon fibre on the outside, which looks fantastic against the Steel grey bodywork. It wears a Vorsteiner carbon bonnet and carbon front bumper, carbon front wings, a CSL carbon bootlid, carbon rear bumper, carbon side mouldings, carbon roof spoiler, carbon Schnitzer mirrors, even a carbon fuel filler flap. There are more carbon panels on the car now than there are regular body panels, it’s really something, and makes the car utterly spectacular. The interior is has also been treated to a whole heap of carbon goodies, including dash trim, door pulls, steering wheel trim, steering column and gearknob, gear surround and handbrake lever. It’s a veritable feast for the eyes. In the early stages of the project, Andy picked up some rather sexy Cobra Daytona seats, which were already trimmed in black Mercedes leather and black Mitsubishi Evo X alcantara and finished with gold stitching, and they look great in the car, really filling out the interior and making it a rather more special place to sit. They’re mated to threepoint harnesses, which are mounted where the rear seats used to be, and naturally there’s also a host of gauges, we’d have been disappointed if there hadn’t been what with this being a turbocharged car and all. They include an Innovate AFR gauge, a trio of HKS gauges to monitor boost, exhaust temperature and pressure and there’s also a HKS turbo timer ensuring that the turbo stays healthy.
So, man builds supercharged E46 M3 and buys turbocharged M3, drives off into the sunset, lives happily ever after etc, right?
Well, not quite… “It’s a good job Andy pipped me to the post on the turbo car,” admits Jaime, “as he spent a lot of money on this M3, so I really reaped the benefits of all his hard work. It was a pleasure to scratch that turbo M3 itch that I’ve had for years, watching all those turbo M3 videos on YouTube, and it is fricking awesome,” he grins, but after buying the car from Andy last July just one month passed before Jaime had put it up for sale himself. “I needed to try it out for a while to see if I was happy to make this my new track car, and after testing it back to back with my supercharged one I decided it wasn’t for me. I have a bond with my supercharged one and prefer everything else about it, as does my other half, Terrie, and I have to live with her so she has a big say in what I do,” he laughs. Unsurprisingly the turbo M3 sold very quickly but surprisingly Jaime has now put his supercharged M3 up for sale as well, and as we put the last of these words to paper it looks like it may have found a new home… “I’ll be very sad to see it go,” he says, “and so will Terrie as we’ve both done a lot of track days in it and she’s learned a lot from driving it and really enjoys it,” but that’s just how it goes with modified cars, we suppose, it’s very rare for them to have any sort of permanence and selling the cars we’ve poured so much of everything into is a just part of the life we lead. They do say that it is better to have loved and lost than never to have loved at all, though, and while we’re not sure if Jaime is planning to go as far as this with the E92 M3 he’s thinking of buying next, he can at least say that he’s been the owner of both a turbocharged and a supercharged M3, and there’s not many people that can.

/ #Audi-S6-JNL-Racing has created this highly-tuned 650+bhp monster of an avant – surely the finest Ur-S6 in the world… Words Davy Lewis /// Photography Matt Dear
JNL Racing's fierce 5-pot unleashed.
UR-S6 JNL Racing’s 520bhp avant
I first met JP, the main man at #JNL-Racing , at Santa Pod back in 2009. I was working on the now defunct Redline magazine and we’d got together a selection of the UK’s fastest tuned cars to go head-to-head in our Fight Club event. The premise was simple; entrants had to take part in two disciplines – a quarter mile and then a handling course – with the best overall time winning the day. Several Audis took part including Dialynx’s black SWB quattro and TTS Roadsport’s TT RS, but the one that stood out was a humble estate.
This stock-looking #1996 #Audi S6 #Avant C4 / #Audi-A6-Typ-4A seemed a bit out of place among the track prepped competition – which made it all the more impressive when JP proceeded to kick the arse out of it, laying down some impressive times in the process. All of which he did with a smile on face. Here was a man who clearly didn’t take it too seriously. However, when it comes to tuning, he is deadly serious.
Specialising in bespoke, hand-crafted cylinder head work and engine builds, JP has carved out an enviable reputation. Although VAGs feature heavily, he works on anything and has customers all over the world; working with anything from old school E-Types to the latest Japanese, European and US brands.
I bumped into JP just before we launched AudiTuner and said I’d love to feature the S6 when it was ready. It had come on a bit since the first shootout, that’s for sure. JP said he’d love a feature – especially if it made the magazine on sale in December as that’s his 40th birthday. So, here you go, JP – many happy returns!
With so many Ur-S6s pulled apart to scavenge their engines it’s not easy to find a stock car, let alone a 650+bhp weapon that’ll worry most supercars. “There are only 55 cars left on the road in the UK, and 85-90 left in total,” says JP. So what made him choose such an unorthodox Audi as a project?
“I had an Audi 200 running a tuned 10v engine, but it caught fire and I needed something else,” he recalls. “A mate had an S6 and I fancied an estate, so began looking for one. I found this one for sale for £2.5k and jumped on it quick.” From here the engine work came thick and fast as JP focused on creating a fast daily driver. “Being a daily, all the work had to be done over the weekends so that I had the car ready for the Monday school run,” he laughs.
The 20v engine was tuned with a ported head, uprated rods, a 63 hotside 3076 turbo on Wagner manifold, and SFS hoses as boost pipes. It made over 500bhp and offered plenty of fun. But, the constant flow of work on other fast Audis got him thinking.
“I built one of the UK’s most powerful B5 RS4s; I think it still holds the record on MRC Tuning’s dyno with around 780bhp and 1000Nm,” he smiles. “I did a 3.0 litre stroker kit and that car made me stop and say, ‘Why am I building all these fast cars for others and not doing my own?’” The RS4 had certainly made an impression. “You know that feeling as a passenger in a really quick car when the driver accelerates and you feel a bit sick and light headed – it catches you off guard. Well, I had that as the driver in the RS4! I decided that’s what I wanted to achieve in my S6.”
The engine itself is based around a 2.5 diesel block, which effectively created a stoker kit (the original was a 2.2 of course). Clearly a diesel block is designed to run in a diesel configuration, so JP welded up any holes and channels that were not required and added holes for the stuff he did need. Custom Pauter rods and JE pistons from a petrol engine were then added. The whole build needed to be bullet proof, so Mahle motorsport bearings were added plus a main girdle to prevent bowing at high RPMs.
Key to this estate’s sleeper nature is the fact that, to most people, it looks pretty innocent. Aside from the 9x18in Rotiforms, which necessitated the custom wide arches being fabricated by Ish and the crew at Quattro Coachworks, this looks to all intents and purposes like any other mid-90s Audi estate. This is just how JP likes it. “When I drive it through a village, people turn to see where the noise is coming from but don’t even look twice at the car – they’re looking for something that looks like this sounds!” With a 3.5in exhaust and 2.25in screamer pipe, it certainly makes all the right noises, just in a discreet package. But, as we all know, appearances can be deceptive.
Drop the hammer in this sedate looking Audi and it’ll attempt to head-butt the horizon at a startling rate. Having experienced the all out mayhem of 650bhp, JP has temporarily turned it down a few notches to an estimated 520bhp. And the rest of the car has been suitably uprated to ensure it’s provides a stable and safe ride. “It got to 650bhp with a slipping clutch, but there was nowhere you could properly open it up without getting into trouble,” he smiles.
I ask JP what it feels like when you really drive it hard at 650bhp. he pauses for thought, then says, “To be fair, I think my youngest son summed it up best when he was about ten,” he continues, “I launched it hard and he said it felt like his willy had gone into his back!” An unconventional response perhaps, but then that’s JP all over.
You get the feeling that he tells it like it is, with no bullshit. If something proves to work well, then he’s the first to praise it. But equally, if something doesn’t do what it says it will, he’ll be brutally honest. This sort of candour is refreshing in a scene that can attract people who like to make unsubstantiated claims, especially when it comes to power figures. But, JP has earned the tight to question things. He tests everything he does – often to destruction – to ensure that any upgrades not only deliver the goods, but also stay in one piece. As he says, “You need to blow things up to find the limits.
How else are you going to know how to improve on the original design?”
While there’s no doubt that JP was put on this planet to make cars go fast, he has a very specific focus. Everything must be about making the car perform more efficiently, which in turn makes it faster and more reliable. So although huge turbos combined with a remap and supporting upgrades can achieve eye watering power figures, it’s often at the expense of drivability.
“My S6 has a usable powerband from 3,250 to 8,200rpm – I see some of the German tuners with 1200bhp with cars that have nothing until 5,000rpm – that’s no use anywhere except on a drag strip,” he comments. Part of the reason behind the chosen upgrades (you can see the full list of goodies on the last page) was to show what could be achieved, without simply buying everything that’s available. “I saw so many owners on forums going on about how much they’d spent on this and that, and I thought, hang on, you don’t really need half of that.” So JP set about proving it with his S6 build. In the process it became the demo car for the business.
It’s currently running a baseline map that JP did himself, which he says was pretty straightforward using the 2D mapping of the Maxx ECU set up, “It’s easier for a non-IT guy like me!” The plan is to start upping the power again now that the rest of the car is ready to take it. ECU legend, Jonus Racing, is due to fly over to the UK to work on a bunch of cars, so JP’s S6 will be in very good hands. “This is the final throw of the dice – I won’t be re-doing this car again, so it has to be right,” he says.
As a cylinder head and engine building specialist, JP’s philosophy is to make engines as efficient as possible. Rather than simply bolting on a bigger and bigger turbos, he looks at ways to make more power off-boost with a less spiky delivery, while holding peak power for as long as possible to the redline. For those who are used to the kick of a big turbo coming in at 4,000+rpm, JP’s set ups can feel like the car is actually slower, but one look at the speedo will show it’s moving faster than the rev counter. By maximising the efficiency of the engine, including the head flow, there’s less pressure on the turbo, which in turn will be more responsive, with a wider power band – all the key ingredients of a usable, fast car. As JP says, “The proof is always in the performance – it either goes fast or it doesn’t.”
With lots of usable power, the brakes and chassis had to be more than up to the job of keeping this big estate on the road. A set of custom front coilovers were created by JP using shortened Bilstein B8 inserts. Gaz adjustable dampers bring up the rear, together with custom pig-nose springs and an Apikol uprated ARB. 2Bennet adjustable top mounts allow the perfect caster/camber to dialled in for that crisp turn in – not something usually associated with nose heavy 90s Audis. With a full complement of uprated bushes and solid sub frame mounts, this near 20-year old S6 now handles with aplomb. The Wavetrack diffs front and rear certainly help deliver the fun factor – whether launching hard or hitting twisty roads – especially with the re-timed factory Torsen unit that JP built up now giving a more rear-biased delivery over stock.
With plans to drive this thing hard on track, JP has wisely upgraded the brakes. The B7 RS4 calipers have been fully rebuilt together with high-temp seals and meaty 360mm discs. With Yellowstuff pads all round and DOT 5.1 fluid, this set up provides ample stopping power.
Inside, this mid-90s estate has been treated to a selection of upgrades befitting something with serious performance. The front seats are the first items that jump out at you. The carbon fixed back buckets look like they came out of a Porsche Carrera GT – but surely not – those things are about £500k now!? “They’re actually copies,” admits JP, “but they’re very good ones. They came out of a Porsche – I got them shipped over from LA Porsche dismantlers in the US.” The leather wrapped seats were in decent nick, although JP has changed the colour of the seatbelt guides, before having them recovered in leather and black Alcantara. They really look the part, right at home in the S6’s cabin complete with OEM carbon fibre trim. The rears were trimmed to match. One thing you wouldn’t see in a 90s estate is a 10.5in tablet fixed to the dash. This wifi-enabled device allows JP to keep an eye on the vital stats via the Maxx ECU.
Having followed the progress of this car for the last six years or so, it’s great to see it almost finished. Once the final mapping session has been completed by Jonus Racing, JP is hoping for up to 680bhp on V-Power and 700+bhp on E85. This S6 is beautifully engineered, extremely rapid, highly usable and, like JP himself, a little unconventional. We love it!

There are very few UrS6s left now, so here are three other S6 variants to consider...
Audi C5 S6 1999-2003
This 4.2 V8-powered S6 arrived in 1999 and went down a storm. The beefy V8 gave 335bhp and made all the right noises. The only downside was that tuning the NA lump was tricky and it liked a drink. Fewer and fewer of these around now and many have fallen into the hands of those that can’t afford to run them, so if you’re after one, be very choosy. Avants are more sought after than saloons.
Audi C6 S6 2006-2011
Launched in 2006 the C6 was packing a NA version of the 5.0 V10 from the RS6. This ten-cylinder monster gave it the sound of a supercar, all wrapped up in a very discreet saloon or estate. Loaded with goodies and that fabulous 429bhp engine, we’ll never see the likes of these large capacity cars again. Not cheap to run and expensive to fix, they are still very desirable. Available in avant and saloon, if you’re after one, make sure it’s been well loved and comes packed with options.
Audi C7 S6 2011-present (2017)
After increasing its capacity with every new model, the latest S6 goes back to its turbo charged roots and back down to a V8. Great news for tuners as the 4.0 V8 twin turbo can easily be cranked up to RS6 levels of grunt. A remap, full exhaust system including downpipes and uprated air filters will see you on the way to 550+bhp with more available depending on how deep your pockets are. Better still, unlike the RS6, you can get the S6 as a saloon, so you could create one of the fastest four-doors around – a true sleeper.

- Post is under moderationOLD DOG NEW TRICKS
With a turbo’d S54 stuffed into its engine bay, this E21 has an eye-watering 1000whp to play with.
Jørgen Aune’s got an addiction to old-skool BMWs, big engines and big turbos. There was only one way his E21 project was going to turn out, and we love it… Words: Ben Koflach Pics: Arild Dyrkorn.
I’ve been interested in cars all my life,” explained 27-year-old Norwegian, Jørgen Aune. “I grew up on a farm, so I began to drive at 13 years of age on the fields. My first car was a Datsun 120Y that I owned with some buddies, but BMW has always been my favourite brand. My first BMW was an E21, which I shared with a friend. I fell in love with the six-cylinder noise and the E21’s looks.
“Then I had an E21 323i with an M30B35 engine, E30 M Tech interior, Brock B1 wheels and LSD. After that, I had an E30 325, into which I put an M106B35 turbo engine. I put a huge truck turbo on it and ran it with about 400bhp at the wheels through an E30 M3 dog-leg gearbox.
“I studied industrial mechanics, and this enabled me to make the turbo manifold and rebuild the intake, as well as make many other custom parts. A couple of cars later, I had an E30 again, this time with a S38B36. I decided to turbocharge it, so bought forged pistons and rods, as well as a Borg Warner S475 turbo. I made the intake plenum, turbo manifold and all the other custom parts required to make the engine fit myself. I also made the car into an M3 replica using only original BMW parts and painted it Daytona violet. It had 802hp at the wheels at its peak.”
Gulp… well, while some of us can claim to have messed around with various project cars in our time, Jørgen’s really got stuck in at the deep end since the start. With his fabrication and engine-building skills, as well as the fact that he now works in a bodyshop, you could say that he’s got all the areas covered. You could, in fact, say that his entire car history has built up to building his latest E21, which is one of the most comprehensive and best-looking first-gen Threes we’ve ever seen.
“I decided to build this E21 when I felt that the E30 M3 rep was done,” Jørgen told us. “I was either going to rip the E30 apart and rebuild it or sell it and use the money to build a new car. I wasn’t sure what I’d use as a new car, but the ’78 E21 320 sitting outside my garage did cross my mind – it was in very bad condition though, so I went to Kristiansund in October 2010 and bought this ’82 316 for 3000 kroner.”
Not one to waste time, Jørgen immediately set to work on his new project. “The car had been standing outside for around seven years, so the floorpan was rusty, as were the rear fenders and trunk,” Jørgen explained. “It really looked bad but was still better than the 320!” The first thing he did was strip the E21 right down to a bare shell, giving him a clean pallet to work from, as it were. Then he started to cut away the firewall and transmission tunnel to make space for the engine and gearbox. “The plan at first was to use an S38B36 turbo again, but I decided to go for the S54 when I found one very cheap,” he explained.
Having driven the somewhat front-heavy S38 E30, Jørgen was keen to make this project a little different, too. The engine was mocked-up in the engine bay, though placed 30cm further back than usual to even up weight distribution. This meant that he had to build a new firewall and gearbox tunnel to allow fitment of the chunky E39 530i gearbox he intended to use. Next up, he moved to the rear axle as with a target figure of 800bhp he needed something stronger to equip the E21 with. “I used the entire rear suspension from the E28 535,” Jørgen said. “Naturally it was too wide, but I narrowed the mounts to make it fit. E28s are 80mm wider at the back, so there was very limited space for wheels in the arches.”
Jørgen’s solution? He cut the rear arches out and then welded them back in with extra metal to make them 40mm wider on each side, resulting in him having enough room to run monstrous 10x17s out back if he wanted.
“The wheels were the first thing I bought when I started the project,” Jørgen revealed. “I like old-skool wheels and the AC wheels fit well on the E21.” We couldn’t agree more, and in 8.5x17” and 9.5x17”, with stretched tyres, they look absolutely spot-on. Having said that, since the shoot they’ve been sold. What will come next remains to be seen. Getting back to the car itself, if you’re somehow not impressed yet, then you’re about to be…
“For the front suspension I modified E34 M5 control and caster arms to fit the E21’s chassis.” Jørgen said. “I welded new brackets and mounting points to the body, all of which were raised up so that the geometry wouldn’t be affected; the plan was always to have a low car!” This level of forward thinking and clever fabrication is something we don’t often see – Jørgen’s entire E21 is a feast of details both above and below the skin. “I then bought an RHD E46 M3 steering rack. The E21 and E34 have the rack behind the wheels, whereas the E46 has it in front of the wheels – a left-hand drive E46 rack would have meant that I’d have reversed steering, so I mounted the RHD rack upside down!”
Completing Jørgen’s innovative and effective setup is a set of fully adjustable XYZ coilovers, which were actually designed for an E30 but have been custom-fitted to E34 M5 struts to tie in with the rest of the setup. The brakes are also from an E34 M5 – it really is a comprehensive setup, and is governed by an OBP bias-adjustable pedalbox, as well as the all-important hydraulic handbrake.
While the welder was out, Jørgen addressed the rotten parts of the boot floor and floorpan. He also fabricated a custom eight-point roll-cage, which not only triangulates to the front suspension turrets but is linked to the rear subframe and diff mounts, creating a seriously rigid and strong shell. The spare wheel well was removed, while everything was measured up and prepared, where necessary, for the pile of parts Jørgen was waiting to fit.
Before adding anything else, though, all of the sound-deadening and other clutter was stripped right back, meaning that a thick coat of stunning Space grey could be applied, both inside and out, having been prepped by Jørgen and his friend Per Egil Hendset, with Frode Øyane applying the paint. AC Schnitzer mirrors and an Alpina front lip were also dropped off at the painters, too. “Since I love the looks of E21 I didn’t want to put on much styling,” Jørgen pointed out.
With that completed, the E21 ready to be built back up into the spectacle that it now is. Beginning with the interior, thanks to that pedalbox and a custom steering column, Jørgen has been able to fit the seats nice and far back, assisting weight distribution and easing the fitment of parts around the custom bulkhead. The seats he opted for were Sparco buckets, which along with sixpoint harnesses and a Sabelt steering wheel make for a rather purposeful inside. The dashboard is the original E21 item, though the standard clocks have gone. In their place sits a neat sheet of aluminium with only the vital readings to ensure Jørgen knows the state of the engine’s vitals when attacking at full pelt.
In the boot you’ll find a 40-litre alloy fuel cell, along with a pair of Bosch 044 pumps and an Aeromotive filter, all designed for one thing: maximum performance. Which is just as well, considering the work Jørgen’s put in under the bonnet. As already mentioned, he’d managed to pick up an S54 nice and cheap, but there was no way it was going to stay anything like standard. “When I started the engine mods the plan was 800 horsepower at the wheels,” he grinned. “I built the engine myself. It took about a month. Once I’d received all the parts I needed the job was easy.”
The block itself has retained the standard 3.2-litre capacity, though understandably Jørgen saw it fit to upgrade the internals using forged Pauter rods and pistons from CP Pistons, which give a compression ratio of 9.0:1. ARP main studs finish the bottom end. The head also remains in standard specification, although it was completely overhauled and bolted down with ARP studs, too. The VANOS was blanked off with JAAS Performance plates. Even the original headgasket remains; it’s a real testament to just how strong the OEM components can be.
Where things have really been stepped up is in the gas flow in and out of that head. In case you didn’t guess, that lowered compression ratio isn’t just for the sake of it – it’s to allow huge amounts of forceinduced air into the cylinders. This comes courtesy of a sizeable Precision 7675 billet turbo, which is low-mounted on a custom JAAS Performance manifold. Out the back of the turbo is a custom JAAS 4” exhaust, while the intake tract goes from the turbo to a custom intercooler, which is actually quite well hidden in front of the radiator. From there the air is forced into a custom JAAS intake plenum. With all the crackle black powdercoating and the fact that Jørgen has chosen to retain the standard engine cover, it’s a surprisingly OEM-looking installation.
Managing the boost pressures comes down to a 75mm PPF dump valve and a 60mm PPF wastegate, while the fuelling is taken care of by huge 1680cc Bosch injectors as well as an Aeromotive fuel pressure regulator, all linked up with neat AN8 lines and fittings. Governing the whole lot is a Elektromotive Tec GT standalone management system, while cooling has been left to an alloy radiator, electric water pump and electric fan.
“I’m very happy with the engine,” Jørgen said. “The only problem we had was the cam adjustments. The first time we had it on the dyno the powerband was terrible. But after a little adjustment together with Geir Haugen from Bjørnstad Cars we dyno’d it again and it was much better providing a wide powerband and peaks of 1000hp and 675lb ft of torque at the wheels at just 2 bar of boost! It blew my mind!”
There’s certainly one thing for sure – with the level of re-engineering and performance that this E21 boasts, it’s got to be one of the best in the world. In the pursuit of such lairy specifications it could have easily ended up looking like something from a horror movie, but with a clear love for the original 3 Series, Jørgen’s respect for simple styling and engineering, it’s become a real spectacle.
The interior may be built for purpose, but it looks really good, too!
A lot of work has gone into this E21, and it really shows…
Check out the spec list and you’ll see a number of parts on this E21 that were made by JAAS Performance. Well, you may be interested to hear that it is in fact the title under which Jørgen and his good friend Anders Skei operate. The pair fabricate all sorts of incredible components, as can be seen from Jørgen’s E21. Anders is a BMW fanatic too, as it happens, though he chose Toyota 2JZ power for his E34 M5. With 894bhp at the wheels, it’s no slouch!
I built the engine myself. It took about a month. Once I’d received all the parts the job was easy.

- Post is under moderationNOTHING IS IMPOSSIBLE 720hp turbo #BMW-E36 hardcore British built M3. We revisit an insane turbo E36, now pushing 720hp. Ignoring conventional routes, Steve Will has created a turbocharged E36 M3 that performs like no other… Words: Stav Neophytou. Photos: Andy Starkey.
While turbocharging in-line six #BMW engines has been the norm in Europe and the USA for decades, until recent years it’s been a rarity in the UK due to our cars being righthand drive. BMW sixes are canted towards the exhaust side, which also happens to be the driver’s side on right-hand drive cars. This means a severe lack of room for not only the turbo and manifold but getting a suitably large exhaust downpipe past the steering column is a real nightmare, too. However, despite these fitment headaches, turbocharging is finally taking off in the UK BMW scene.
A man clearly ahead of the times, though, is UK resident Steve Will. This incredible E36 M3 is his, and it’s been turbocharged for the best part of a decade now! While it’s been a long road, full of pitfalls and learning experiences, the end result is jaw-dropping.
Steve bought this car back in 2005 and turbocharging it was always on his mind since driving a turbocharged 635CSi many years previous. Despite the perceived impossibility of a RHD Turbo E36 M3 back then, it was barely two years later before it had its first incarnation as a turbocharged engine. This first setup used a cast log manifold by South African BMW expert Savspeed, a Turbonetics T70 turbo, and a fully-forged engine with a compression ratio of 9.5:1. Unfortunately, while clearly incredibly powerful, the combination of the high compression ratio, pump fuel and suspect mapping meant the engine expired due to severe detonation while still being tested and mapped at Bruntingthorpe Proving Ground.
Thankfully this initial disaster was covered under the tuner’s warranty, so the engine was rebuilt with a more pump-fuel friendly 8.5:1 compression ratio.
Sophisticated Motec engine management was fitted and the car was finally dyno’d at a ballistic 670hp and 500lb ft of torque. While we really don’t need to tell you how incredibly fast a 670hp E36 is, due to the big turbo and basic log manifold it wasn’t the most efficient setup in the world. In fact, even Steve will be the first to tell you it was actually very laggy. While it hit the 350hp mark at 5500rpm the power then literally jumped up 100hp every 500rpm from then onwards, pulling hard until over 7500rpm. It was an absolute animal; insanely fast but far from controllable!
The engine stayed in the above spec for a number of years but as the car was primarily used as a drift car, both for fun and competition, outright power became less important than response and drivability. So, when the engine finally failed in 2011, plans were made for a more user-friendly engine spec. While the cast log manifold was still seen as the only option, Steve increased the compression ratio to 9:1 and fitted a smaller PT5862 turbo – Precision’s equivalent of the popular Garrett GT35R.
After some expert mapping from Greg at Protuner the way the car drove was transformed, with 350hp now coming at just 3500rpm. At the same rpm the engine was also making well over 500lb ft of tyredestroying torque. Peak torque was incredible, 650lb ft, and response was instant, too. Compared to the original larger turbo, however, peak power was down over 100hp at 560hp, and peak rpm was much lower, too, with the graph flat-lining from 5000rpm until just over 6000 when it started to drop.
There’s no doubt 560hp and 650lb ft are supercar-smashing numbers in most people’s eyes, and if Steve knew no differently he’d no doubt be over the moon with the performance but despite the amazing torque and response, his previous experience of having a huge 670hp and a screaming high rpm performance was impossible to forget. In fact, he was so used to the insanity of the old setup he called this one “boring”, which leads us to where we are today…
What Steve ideally wanted was the best of both engines: the insane power of the big turbo engine but with the torque and response of the small turbo engine. Pretty much everyone he spoke to said that was impossible. Undeterred Steve employed the services of someone who sees the word ‘impossible’ as a challenge: Thomas Zurawski of Zurawski Motorsport in Ledbury, Herefordshire.
While the engine itself was bulletproof, and it’s hard to beat a #Motec-M800 ECU, Zurawski Motorsport is an expert in custom turbo setups and could see the existing design left a lot to be desired. Not only was the cast log turbo manifold considered a poor design but the inlet plenum, intercooler, exhaust system, and air filter setup were all on the list for improvement. Tubular twin scroll turbo manifolds didn’t previously exist for RHD BMWs due to the lack of room but the Zurawski design fits perfectly. And not only does it flow far better than a restrictive log manifold but the twin-scroll design drastically improves turbo spool up, allowing a bigger turbo to be used without losing drivability.
To further aid spool and throttle response, twin WRC anti-lag valves have been fitted, allowing huge amounts of airflow to go direct from the compressor to the exhaust manifold which, along with fuel and ignition adjustments from the Motec ECU, give the engine the ability to stay at full boost even when the throttle is closed, not to mention the rapid-fire bangs and huge flames from the side exit exhaust!
The other big change to the engine is certainly the most controversial: the inlet plenum. The shape and design of it is certainly a world away from typical designs and, due to this, many naysayers claimed it would be restrictive or simply not work. The reality is, however, it’s actually a commonly-used design in turbocharged race engines, as found in WRC, RallyCross, and LeMans. The unusual design gives equal airflow to each cylinder, something that’s a big problem on turbocharged cars, especially on in-line six engines, and by allowing the cylinders to receive equal amounts of airflow improvements are seen in power, spool up, reliability, and to safe boost limits.
In addition to the manifolds, the entire turbo system – from air filter to exhaust tailpipes – was custom-made from scratch by Zurawski Motorsport for maximum flow and efficiency. It includes a huge grillemounted air filter, an enormous intercooler that necessitated the rear mounted radiator conversion, twin external wastegates, and a full custom exhaust system, with a very cleverly designed downpipe that somehow manages to snake past the dreaded RHD steering column!
Of course, the most important part of any turbo system is the turbocharger itself, which is a BorgWarner S300SX 9180 turbo, with a twin scroll T4 turbine and billet compressor. This turbo is actually bigger than the previous original laggy unit, so surely this new engine can’t be very responsive? Think again…
With the car once again in the expert hands of Greg at ProTuner, the new setup made a touch over 600hp at just 1bar boost, and 700hp at 1.5bar, 30hp more than the traditional-style turbo setup using the log manifold. While the power is impressive, what really makes it special is this time he also had an insane 730lb ft of torque, with over 500lb ft of that by just 3700rpm. Yes, it spools as fast and makes even more torque than the small turbo did but makes more power than the big laggy turbo! The currentspec engine actually makes more power and torque than the original engine right across the rev range, from 2500rpm until over 7000rpm. In fact, at 4000rpm it now has 375hp and 490lb ft more!
Buoyed on by these incredible results, the car recently returned to the dyno with 109 Octane race fuel where it made 720hp and over 800lbft at 1.4bar boost. The new fuel gave such incredible response and torque that, by the time of writing at least, Steve’s been unable to get traction at any higher boost than that. Once he finds a traction solution, though, he’s hoping for 800hp plus. Considering the current results, even over 1000hp looks to be easily achievable with only a slight increase in turbo size.
While we make no apologies for concentrating so much on Steve’s groundbreaking engine, the rest of the car is no less wild, both in looks (thanks to the M3 GTR wide bodywork and Team Dynamics motorsport wheels) and in performance (thanks to a spec that is truly world class).
On the inside there’s a comprehensive custom roll-cage that ties in to the diff mounts, a sophisticated rear mounted radiator setup that draws air through the side window ducts and exits via the rear diffuser, while underneath there’s a drift- specific front suspension design with incredible amounts of steering angle.
What’s perhaps most impressive is the thought put in to all the various parts fitted to this car. While you will no doubt have read the comprehensive spec list and recognised most of the parts’ manufacturer names, Steve has built this car more like a Works race car than a typical privatelyowned car, with the reliability and strength of all components being the primary consideration. This doesn’t just mean strong and effective parts but even things like the fuel and oil pressures are continuously logged by the ECU, which shuts down the engine if something deviates from the specified parameters.
So now the car is complete, what does Steve want to do with it? Well, despite being used for competition drifting for some time now, he’s more interested in just having fun in it without the stresses of trying to win trophies. On the rare occasions this car isn’t on masses of opposite lock, Steve’s actually very keen to take it back to where the original turbo engine expired, Bruntingthorpe Proving Ground, this time to break the 200mph mark – something it should do with ease.
For a car built with nothing but Steve’s own enjoyment in mind, the progress of this build over the years, and especially the final result, is a lesson for all of us. Not only is this sort of unbelievable, best-of-all-worlds, engine performance perfectly possible (and reliable if done correctly) but putting true thought in to what you are doing, taking influence from world-class race cars rather than simply following the crowd, really pays off in the long run.
The rest of the car is no less wild, both in looks and performance.

Steve wanted the power of his big turbo engine but with the torque and response of his small turbo engine.
Everything about this extreme E36 M3 means business. Side-exit exhausts look and sound awesome. Custom alloy rear diffuser allows hot air to be pulled away from the boot-mounted radiator, itself fed by pipes attached to side window intakes.Stream item published successfully.

This BMW-loving father and son duo have built themselves two very different 2002s: one S14-powered, one turbocharged, both rather brilliant. Two 2002s, two very different approaches. A father and son team have put together this formidable pairing of modified BMWs, both brimming with citrusy goodness… Words: Daniel Bevis. Photos: Patrik Karlsson.
Nominative determinism is an interesting idea. It’s a very real thing, positing that certain people’s futures tend to be mapped out by the name that they’re born with. For instance, the poet William Wordsworth, the racing driver Scott Speed, the meteorologist Amy Freeze, the urologist Dr Dick Chopp (who specialises in vasectomies and really does exist) and the tennis player Anna Smashnova – it can’t be a coincidence that these people have pursued careers that fit their names.
It follows, logically, that while people’s future paths can be shaped by name, there may exist for creatures and objects a sort of ‘colouration determinism’, where destiny can be informed and coerced by hue and saturation. Peacocks, for example, strut about like they own the place because they’ve evolved feathers that allow them to do so, and they revel in it. Little blue showoffs. It’s a self-fulfilling cycle. What does all this have to do with the pair of old-skool 2002s we’re looking at here? Ah, all will become clear. But it concerns, of course, their respective shades of orange…
To begin at the beginning, what we have here are a pair of home-built ’02s that offer far more horsepower than the factory ever envisaged – for we are in Sweden, and that’s just what they do here (the winters are long, there’s not a lot else to do) – built up by a father-and-son team. EWO 172 is a 1969 2002 Ti belonging to Mats Örnberg, and follows a classic approach to the pursuit of power: OEM+ tuning and a solid retro vibe. GEF 588 is the pride and joy of his son, Pontus, and takes a rather more boisterous approach, being a previously humble ’02 with the naughty spirit of the fabled 2002 Turbo woven into its DNA. So let’s start with the older generation first, shall we?
Mats’ 2002 wears Lamborghini Mica orange paint, a shade that suits the sharpened angles of a Murciélago down to the ground. In this instance, returning to our notion of colouration determinism, it speaks of style, chic, passion and flair – the attributes of a carefree Italian outlook, la dolce vita made solid. And as such, Mats has treated the engineering of the car with the reverence it deserves. “We found the body in a barn back in 1996,” he recalls. “When I first built the car up it was running an M10 engine; having fixed up the rust and fitted the steel arch extensions, it was on the road by 1998 in its first guise. The motor was lightly tuned and I ran it that way for a number of years, during the summers that is, with the modifications and upgrades happening over the winters.”
This is a stock tuner phrase in Sweden – it must be terrifying being an elk or a beaver in the springtime over there, when the snow melts and all the nutters emerge blinking from their garages, ready to deploy the extra horsepower they found over Christmas. “I bored it out to 2.2-litres, fitted spikier cams, fettled the suspension, experimented with bike carbs… and then around 2005 or 2006 I fitted the M3 engine.” He says this as if it’s the most natural thing in the world. Maybe, for him, it is.
The E30’s S14 four-pot is a formidable thing; its architecture spawned from the M10, so it’s an entirely appropriate evolution for Mats’s build, and it’s the one four-cylinder engine that, generally speaking, the hardened BMW six-pot fan will make a concession for. It has the weight of history and motorsport prowess hanging from it. “Everything from the 2002 suited the swap,” he grins. “The motor mounts, oil pan, oil pump, the gearbox… the M3 manifold had to be modified a little, and a new exhaust system had to be built, but on the whole it fitted very happily.” Makes it sound easy, doesn’t he?
So in essence he found himself with a classically-tuned 2002 with 199hp at the wheels, something that would have raised a few Bavarian eyebrows in period. The fact that he’s rocking a set of motorsport-chic #BBS-RS wheels and debumpered the thing like a race car merely adds to the feel of 1970s track shenanigans. He’s got buckets, harnesses and a cage in the stripped interior, too, because that’s how a car like this is supposed to roll. Mats has been developing it for years, and this is its ultimate evolution. (Well, ‘ultimate’ in the sense of ‘latest’, at least. We very much doubt he’s finished with it yet.) “All of the renovations and modifications were carried out by me, save for the paint and a few minor jobs like aluminium welding,” he explains, which makes perfect sense really. You can’t be nipping to the local garage every five minutes if your workshop door’s wedged shut by a snowdrift.
So if Mats’ car is informed by the suavity of Lamborghini orange, what’s the citrus situation with Pontus’? Well, his 2002 is slathered in a shade of Harley Davidson orange, which really should act as a statement of intent. This is a colour that forgoes any sentiment of subtlety in favour of brash, forthright shoutiness. It beats its chest with fury like a wronged, bearded leviathan in a Southern biker bar. It doesn’t ask, it just takes.
“This all started in 2012, when Pontus was just 16,” says Mats, immediately shaming most of the dads of our readership into rethinking their ‘birthday present ideas’ list. “He asked me if I could give him some help in working on a 2002 with a turbocharged engine. I told him to talk to my brother-in-law about it, as he had a 2002 that he’d built and registered with a turbo – and it turned out that he’d tired of it and started to strip and sell the parts, so Pontus bought the whole thing and that became the project! We worked on restoring it together, with a new turbo and engine management system, as well as replacing the gearbox and differential, which are from an E28 528i. We also had to scratch-build a whole new fuelling system, and build up the new coilovers, and set up the new front brakes which are from a Porsche Boxster, and…” Well, the list goes on and on. This is very much not a case of tidying up someone else’s project; what Mats and Pontus have achieved here is to take the lessons learned from the former’s protracted dabblings in 2002 fettling and reimagine it for a Generation Y outlook. Forced induction, multi-marque part-sourcing, great big rims with broad rubber, these are all the touchpoints gleaned from a childhood spent poring over Gatebil coverage, and GEF 588 is the natural coalescence of influences old and new. “We had some heat issues with the downpipe in the beginning,” Mats continues.
“The spark plug wires melted, so we had to make a new manifold that would position the turbo a bit further away from the engine. But in general, that’s really the only problem we faced.” Again, he’s making it sound simple. What’s residing beneath that Harleyjaffa bonnet is really anything but: a 2.0-litre motor stroked out to 2.2, with robust pistons and rods, and a Borg Warner S200 boosting happily and filling the system with cheerfulness. The block itself has been partially concrete-filled, an old drag racing trick that adds strength to the cylinder walls and deadens internal vibration. (The necessary compromise is to half-fill it because, unless you’re running a full-race dragster or fuelling it with methanol, you want to keep some of the water jackets free or else you won’t have any cooling.) It is, in short, pretty hardcore. 424hp of hardcore, in fact, with that E28 LSD having all sorts of spiky power to cope with.
Pontus has really gone to town on the aesthetics, too, eschewing his old man’s penchant for retro flair by ensuring that any potential challenger is in no doubt that they’re about to get kicked in the teeth. The 17” Borbet rims give the profile a brilliant Hot Wheels look, all pumped-up proportions and caricaturistic stance, while those Mk1 Golf arches that just about rein them in are an unusual alternative to the more obvious Turbo bolt-ons that most 2002 tuners plump for. The fibreglass front and rear bumpers are an interesting and polarising choice, too; while most people would either run debumpered, as Mats does, or stick a Turbo air dam on the front, Pontus has gone for a set of square-jawed chins that, working with the chunky sideskirts, do a lot to visually lower the car. It’s bound to be a look that puts some people off, but that’s just what we love about it. Who wants to follow the herd, eh?
Certainly not the Örnbergs. “We’re at a point in time where the older generation are talking about their memories of these cars when they were new, and the younger generation think it’s cool that they owned them,” says Mats, with the logic of a seasoned campfire storyteller. “My first car was a BMW and I’ve had one or two 2002s in my time… clearly it’s rubbed off from father to son!”
They’re having a lot of fun with their creations, too. Mats uses his car in autocross competitions, while Pontus can be found drifting his turbo looper when he’s not joining Örnberg Senior for a spot of autocrossing. The respective personalities of their shades of orange have naturally bled into two very different 2002s, but they’re both on a level pegging when it comes to desirability: whether you’re into high-revving screamers or hard-boosting growlers, there’s something lurking for you in the Swedish woods. And if you don’t see them coming, you’ll certainly hear them.
