Sometimes we find a #BMW that’s had so many changes it’s hard to spot them all. Ian Walpole’s E30 drifter is one such car and he did it all in his garage at home… Words: Mike Renaut. Photos: Matt Richardson.
Don’t think of this one as a modified E30. It’s better described as a hand-built race car with a lot of BMW parts. At first glance it looks like a stripped M3 until you realise those arches aren’t quite the same and the back end looks different too… The guys with all the answers are owner Ian Walpole and his mate John Amor who helped him greatly with the build. Between them they’ve built and raced everything from a rally Vauxhall Viva HB to a trials Land Rover. They like a bit of everything, so in 2013 decided it was time for a drift car. “I’ve been into BMWs for a while,” says Ian, “I’ve got an E46 Touring I use for MCC Reliability trials with my dad as navigator – that’s all about stopping in boxes on hills and car control. This E30 was something different again.
“It took us three years to build,” continues Ian, “I don’t know how my wife Sasha put up with it. Just before we went travelling - around 2011 - I’d bought a #1987 #BMW-325i-Sport-M-Tech-1 purely to drive about. It sat on the driveway unused and when we returned I saw rain had got inside and it was all mouldy. After an MOT and some TLC I tried selling but it wasn’t even worth £1000 so I bought an HX40 turbo and a manifold kit for it. The kit was awful, the ports were offset in the wrong place and John and I like to do things properly, so we started to modify parts to fit and the whole build spiralled out of control.”
Caged Laser Engineering laser-cut a plate to fit the turbo and another to fit the cylinder head. “We then cut up the cheap manifold and fabricated new flanges and pipes creating a split pulse manifold with external 60mm wastegate and a screamer pipe exiting from the offside wing,” says Ian. “Then someone offered me £700 for the Sport body kit meaning we had money to play with. We pulled the motor apart and the crank was worn, so in went a 2.8 crank from an M52 and shorter rods, we balanced it all to within 0.1 of a gram and honed the block.” As you can tell, Ian has a well-equipped workshop…
Next the head was reworked by Simon at Orchard Performance for a broad torque band, with oversized valves and porting allowing decent horsepower from a non-aggressive Schrick camshaft. The combustion chambers were modified to improve detonation resistance under boost and optimise combustion, resulting in a fastburning compact chamber that now runs cooler than stock. That alone resulted in an engine with torque enough to get the rear wheels spinning from 2500rpm to the redline. One of the few other areas the guys didn’t do themselves was the baffled sump, “We made one,” says John, “but kept thinking it didn’t quite look right. We reasoned that big companies know what they’re doing when it comes to designing parts, and the idea of oil starvation because we’d made a design mistake was scary, so we bought an off-the-shelf baffle for the sump and welded it in.”
Currently the car runs 6psi of boost, which means 250whp. “On the first dyno run the boost was cranked up to 12psi which produced a puff of steam from the expansion tank and a misfire,” remembers Ian. “I knew the head gasket was the weakest point but I briefly saw 350whp! We’ve now fitted a Cometic multilayer steel gasket which is thicker than the old one, lowering the compression from 9:1 to 8.5:1 and allowing us to safely run extra boost.” That nitrous bottle in the back actually connects to the chargecooler, a £1000 item bought for just £70 on eBay, “We made a spray nozzle on the lathe so 2bar of pressurised nitrous is fired into the cooler, which freezes the inner radiator veins at -136ºC. This provides constant cool air to the engine,” he says. “I didn’t like the idea of injecting nitrous straight into the engine,” explains Ian, “but used this way it’s a great method of keeping the temperature regulated. When the car’s on the dyno being tuned it’s going to have a different temperature to when it’s outside on a track in hot sunshine.
This set up keeps it constant to the dyno temperature conditions.” Waste nitrous exits via a pressure relief valve and homebuilt spray bar over the outside of the charge cooler – again helping it keep an optimum temperature. After all that, the boys kept things simpler with the gearbox; it’s the standard 265 Getrag five-speed unit with uprated pressure plate, although the friction plate has been modified with six sintered paddles and uprated springs by Precision Clutches of Yeovil.
When it came to the body work, there was a clear plan, as Ian explains: “Building this car was all about airflow and weight saving.” The standard bonnet slam panel was getting in the way of that airflow so out came the angle grinder and the front 10” of BMW dropped to the workshop floor to be replaced by a removable lightweight 25mm tube version. “Yeah it’s a bit frightening doing that,” admits John, “but there are two of us so we knew we could fix anything between us.” Keeping the engine cool is a radiator from a 3.0-litre Mitsubishi GTO, but even then the guys couldn’t leave it stock and have handmade an alloy cowling for the 16” fan, “We also cut off the filler neck/cap and ran a bleed hose to an alloy expansion tank.” The fuel cell in the boot was bought from a hill climb car, “It’s an ATL-style bag tank with alloy shroud and the original BMW fuel cap – one of the few original parts that survived the build,” laughs Ian. Fuel travels via a low-pressure pump into a pump feed surge tank to a modified fuel rail and 600cc injectors, then returns to the tank via an adjustable pressure regulator.
The front spoiler and bumper came from eBay; “It was a cheap part that arrived broken in two. We salvaged it and reinforced it with 0.5” alloy tubing and fibreglass, then cut out the indicator and number plate recesses for better air flow before hanging the bumper on quarter-turn Dzus fasteners,” explains John. The new arches were inspired by a modification Ian made to an Alfa Romeo many years ago and are hand-formed from 16- and 18-gauge steel, while each of the side skirts was made from a single sheet of aluminium, likewise the rear bumper.
“The straight bends for the side skirts were much easier than the two days of TIG welding that bumper needed,” admits Ian. As for the final colour, “The guy who painted it – Luke Harvey of Tytherington Body and Paint - suggested adding rainbow flake into the lacquer over the black base.” It looks like a normal black until sunlight hits it, then it sparkles. Almost everything else is colour coded in Ian’s favourite Kawasaki Green.
The boot lid is steel but there’s a carbon fibre one under consideration, “With a drift car you need a certain amount of weight over the back wheels,” says Ian, “we’re still experimenting – it’s more about balance than pure weight reduction.” That’s an M3 boot spoiler but with homemade adaptor plates to fit the non-M3 boot lid. “I fear we might have to fit a huge spoiler for stability in the future though…” says Ian. The weight saving even extends to having the door internals completely gutted and making up new lightweight door latching mechanisms from 15mm billet alloy – drilled, of course, for reduced weight.
The E30 originally had a sunroof but now even the roof panel is fibreglass - saving 18kg and lowering the centre of gravity. “The roof was £67 on eBay but turned out to be in Glasgow,” laughs John, “we went in a van and did about £200 in fuel; I drove up and fell asleep exhausted when we arrived, so they just dropped the roof in on top of me and Ian drove back. It fitted alright once we cut the steel one off but the glue you use to bond it is £50 a tube.”
The front screen is the glass one fitted at the factory but the rest of the windows are Lexan, “I bought the door pieces ready cut but made the others myself with a jigsaw to cut the air scoops into the quarter windows,” explains Ian. There are four scoops in total: two force air over the fuel pumps and swirl pot, the other pair are powered by two 12-volt in-line boat fans blowing air through the gearbox and differential coolers – mounted between the rear lights – with the air exiting through the space where the rear number plate used to be.
The wheels came from Ian’s 2000 750iL; rear hub adaptors were employed to go from four- to five-stud and give an 80mm wider track. The rear suspension comprises HSD Monopro shocks and springs and adjustable trailing arms, all shod with Powerflex Black series bushes. The rear beam lower supports, meanwhile, are now also stronger and longer, which leads us to the front axle. It’s comprised of E36 HSD coilovers with re-drilled strut turrets and top mounts that are adjustable for caster and camber. E36 front hubs run homebuilt hub adaptors and connect to a Z3 steering rack via E46 inner and outer tie rods with four mm rack spacers added for greater lock. The power steering rack is re-engineered by cutting slots internally, allowing free movement of the rack lubricated by a smear of grease and meaning the pipework, pump and reservoir could be removed. That change not only saves weight but also gives better feedback during drifting.
As for the exhaust system, would it surprise you to learn Ian and John hand built that too from 3” stainless steel tubing? “I cut two 90º bends and joined them to form a T-piece, the exhaust exits just ahead of the rear wheels and as well as being designed for free flow it helps push the tyre smoke back. And there’s plenty of it,” laughs Ian, “I’ve got specialised Achilles purple smoke tyres.”
Inside two Sparco seats make up the minimalist interior with a Momo wheel and gauges from AEM. The handmade dashboard is covered in Alcantara while all the other important control switches – fans, gearbox and diff pumps – are in a strip console across the top of the windscreen. “It looks great,” says John, “but when you’re strapped into the car we found that was the only place where Ian could still reach the switches.” Low fuel, nitrous engage and low oil pressure warning lights are also fitted. The handbrake lever is carved from a single piece of billet aluminium, as are the door handles. The roll cage has been extensively modified too; it’s lightweight 45mm chromoly seamless tube and started out as a six-point cage but now has double that - along with dash bars, more crossbars and strengthened mounting plates. Even the stock heater is now housed in a much smaller homemade alloy surround, “There’s not much of this car we haven’t touched,” admits John.
“When I first saw it in paint I didn’t recognise it as my car,” remembers Ian, “it was stunning. We’re both really pleased with how it turned out.” Did working together ever lead to any arguments about parts choices? “I just left all the difficult decisions to Ian,” laughs John, “Yeah and all the difficult jobs too,” jokes Ian. “It was 50% planning and 50% experimenting, some pieces were a bit scary but we bounced ideas off each other.”
Ian and John both insist this is a drift car, and was never intended to be a show car, but then Ian reveals just how many hours John has spent polishing the engine bay for our photos. “I used an entire tube of Autosol,” admits John, “we weren’t aiming to build a show car but, yes, it did get out of hand.” Thanks also go to Ian’s wife Sasha who apparently “cleans all the bits no one normally sees.”
Surely then, and this is a sentiment echoed by almost everyone who has seen the BMW, the car is too nice to risk smacking into an Armco by drifting? “Of course it’s going to get hammered,” agrees Ian, “but it’s designed to be hardy. The body is mainly steel, the fibreglass panels can be changed in a few seconds since they’re all on Dzus fasteners and we can rebuild anything we damage on the track - I just hope Luke can match the paint again!”

/ #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.
