    DOUBLE DIP #BMW-E46 / #BMW / #BMW-M3 / #BMW-M3-E46

    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.

    NEED FOR SPEED

    This #1989-Audi-Coupe has evolved into, probably, the fastest car on the streets of Finland, with a 0-62mph of 2.3secs, and over 1100hp…

    Flying Finn – 1100bhp Coupe
    Over 1100bhp from this #S2-engine’d monster

    It all started back in the winter of 2010 when I bought the car,” explains owner, Henry Riihelä. “I had a 350hp Audi Ur-S4 at the time and was planning to start tuning it to the extreme. Fortunately, my friend and one of the current IMSA-Sipoo team members, decided to sell his already tuned Audi Coupe quattro to me. The Coupe suited me much better anyway because it’s much lighter.”

    The engine had already been done and it’s testament to the quality of the build that it still runs the same forged internals that were fitted by the previous owner in 2010. Even more impressive when you learn that it’s currently running 1102hp and 1043Nm at 2.9bar! “That is the one reason I believe the engine is still in one piece with the same internals,” says Henry, “because I always take logs from the ECU when I drive it hard and adjust things if necessary – it’s saved me at least one catastrophic engine failure.” The Coupe began with a Holset HX40S turbo and made a very healthy 662hp and 775Nm at 2.7bar on what was then Shell V-Power 99. The spec remained for a couple of years with Henry doing about 30,000km in it.

    “Then in 2012 I changed to E85 fuel and with the HX40S made 698hp and 746Nm at 2.1bar.” However, the turbo was maxed out. Even so, the car ran 100-160km/h in 2.85secs and achieved 100- 200km/h in 5.3secs. “It killed a couple of fast 911 Turbo Porsches on the street – they were sold right after that,” laughs Henry.

    Next came an HX50 in 2013, which Henry admits was an error “I should have gone straight for an HX55.” Even so, with some Toyo R888s fitted to aid grip and the Tatech ECU upgraded from a 6 to a 32, the now 840hp and 860Nm Coupe did 100-200km/h in 4.6secs and 200-300km/h in 12.1secs. “It outran some fast bikes on the streets,” smiles Henry. “But the rear drive shafts started to bend, so a set of billet items were made.” Fast forward to 2014 and some CatCams were fitted, together with solid lifters, while the turbo was swapped for the more capable HX55. “It made much more power at the top end, but it made the same boost at lower rpms as the HX50, so it was all win,” says Henry.

    The car made a best figure of 1019hp and 985Nm at 3.16bar, but it was driven at a less stressful 2.9bar giving around 950hp all summer. Henry continues, “The best races were against a 308whp turbo GSXR 1000 and a 303whp turbo Hayabusa. We did a couple of races from 80-300km/h – the GSXR lost and the Hayabusa runs were dead even. We were all shocked. Nobody thought that this little Audi would be that fast – including me.” That summer. Henry took the Coupe to a non-prepped drag strip where he achieved a 9.9sec quarter mile at 240km/h. “It was a very hot day and I had not tuned the car for that kind of weather (so was running a bit less power), but it was still a real 9sec street car on a non-prepped track and street tyres,” says Henry.

    Also that year, the car did 0-100km/h in 3secs, 100-200km/h in 3.9secs and a standing mile event with a top speed of 337km/h (209mph) before he ran out of gears. It was here that Henry chose to upgrade to a PAR Engineering dog box and sequential shifter, which he says, “Was a big mistake.”

    Sadly the season ended even before it actually started. “First #PAR-Engineering sent the gearset six months late and in my second full pull on the street, the main shaft broke – I was pissed. So we quickly made an IMSA Sipoo main shaft with a bigger chevy spline and have had no issues with that. But the summer had already turned to autumn and the weather was cold, limiting traction.” Despite the cold weather, Henry achieved 0-100km/h in 2.3secs, which is damn impressive. He also discovered he could get all four wheels to spin at 200km/h (124mph). He went on to lay down some epic times – 100-200km/k in 5.5secs and 80-120km/h in one second dead.

    This brings us to 2015, where a few other upgrades were deemed necessary. “We fitted an FHRA-spec roll-cage – the goal was that the car should still weigh the same once it was fitted – 1240kg.” This entailed saving weigh elsewhere, which included a composite tailgate with polycarbonate window (-15kg); the sunroof was removed (-16kg); excess removed from interior (-15kg); lightweight race battery fitted (-15kg). At this point a Quaiffe LSD was installed up front to aid traction, while the piston pins were changed to heavy-duty items (the old ones were starting to bend) and the exhaust manifold swapped for a larger item. The cylinder head was also ported to the max and the intake manifold was tweaked with larger valves fitted. “On the dyno, with same HX55 hybrid as last year, but less boost (2.9bar) we made 1102hp and 1043Nm.

    And that pretty much brings us up to the present day. “Nothing special was done for 2016,” says Henry. “We changed to a Wavetrac LSD at the rear and by the start of the summer broke the PAREngineering 3rd gear due to the malfunction of the SQS shifter. The shifter never really worked well, so I had to change the H-pattern back.”

    “My goal was always to make it the fastest car on the streets of Finland – an ultimate sleeper. I think I’ve achieved that now,” says Henry. But he’s not done, not by a long shot. “For 2017 my goals are an 8sec quarter mile and to achieve 0-300km/h in 11secs – both on a street surface, rather than prepped drag strip. I think I have achieved what I started out to do and made the fastest vehicle on the streets of Finland. I just have to get the new air shifter gearbox done – and if someone is faster I’ll have to order an HX60…”

    KING OF THE MOUNTAINS Turbo, wide-arch E30 Cab

    Logically, this E30 should have been scrapped long ago. But when you’re building a big-power toy for motorsport thrills and early-morning mountain runs, logic doesn’t always factor very highly… Words: Daniel Bevis. Photos: Scott Sturdy.

    The Blue Ridge Parkway, running through North Carolina and into Virginia represents one of America’s great fusions of nature and technology. Scenic roads were something that American developers did uncannily well in the early half of the 20th century, and this particular one – a ribbon of Tarmac winding through gorgeous vistas of the Appalachian Mountains – is where Matthew Koppi’s love for BMWs was born. He’s the man behind this Olive green E30, and his passion for the marque stretches back decades. “I first fell in love with the BMW brand in my childhood,” he reminisces. “I live in the scenic mountains of Western North Carolina, and I used to see BMWs all over the twisty Blue Ridge Parkway in the ’80s. As a carobsessed kid the BMW was something that seemed like perfection; so graceful and nimble with timeless design.


    “I bought my first #BMW in 1999,” he continues, “while stationed in Vicenza, Italy. It was a 1983 323i with Alpina cams and other goodies that I didn’t fully appreciate at the time. I bought it because of my childhood infatuation – plus the price was right for a young army private! It was the first car I owned with fully independent suspension and four-wheel disc brakes, and also the first that I could drive over 100mph for extended periods of time without worrying about it exploding. I’ve been a devotee ever since!”

    All of this rather explains Matthew’s latest career move, setting up North Fork Autoworks in Barnardsville, North Carolina. Having turned wrenches for much of his adult career, this seemed like a logical move, although he’s keen to point out that throughout this E30’s build he was a full-time student, working on a bachelor’s degree in Environmental Science.

    “All of the work on the car, from fabrication to paint, both in the engine bay and outside, was done by me,” he proudly explains. “The only thing I didn’t do completely on my own was the machine work, but I was there for every step of the process and even ran some of the machines!

    Basically, I was either directly responsible for every aspect of the car or I was intimately involved.” And with that forthright mission statement dealt with, we should probably rewind and take a peek at where this all started…

    Back in 2010, having returned to school and requiring a sensible-ish runabout Matthew was driving an old Suzuki Sidekick (that’s a Vitara to you and me) and questioning his choices somewhat. It was boring. And life’s too short for boring cars. So the idea of a fixer-upper E30 began to percolate, and you know what happens when the spark of inspiration’s arrived. It’s pretty much a done deal.

    This cabriolet appeared as a shabby little ragamuffin on Craigslist, but crucially the price was low. “The ad stated that the car ran when parked, but now wouldn’t start,” Matthew recalls. “It also disclosed that the interior and top were trashed. I arrived to find a car parked in tall grass behind a tiny house way back in the mountains, in the middle of nowhere! The previous owners were very nice and were at their wits’ end with the car. And they were painfully honest about it all. Truly the thing should have been parted out or crushed, but I was in love.

    It had bad rear wheel bearings, one front hub bearing was shot, bald tyres, ruined leather interior that had hardened and cracked beyond repair or comfort, the paint on every panel was faded and peeling, the battery tray was rusted through, it had an automatic transmission, wrong front wings, cracked aluminium bumpers, and the top was so far gone that there was water pooled in the floor despite the car being under two tarps. True to the ad, the engine would turn over but wouldn’t start, so the condition of the drivetrain was unknown.” Quite a catch, right? So as you can imagine, Matthew snapped it up and lovingly caressed it homeward, all the time reminiscing about those swooping mountain heroes on the Blue Ridge Parkway.

    “First and foremost, I wanted to get it running and replace the top,” he explains. “It needed to be good enough to comfortably drive my young daughters around in as I continued to fix it up, and I originally planned to follow my old formula of decent wheels and lowered suspension… but that was before my first autocross event!” That’s right. The goalposts just shifted. First, though, is the matter of a knackered E30 which needs pretty much everything fixed…

    Job one was to get the old M20 ticking over sweetly and mated to a manual gearbox, something that Matthew did right away before fiddling with chips and fuelling and so on, and this setup lasted a couple of seasons of autocross. But power corrupts, and he was craving more, so he started pooling resources for an M5x swap… until the idea of a boosted M30 caught his eye, and from then on there was only one way forward.

    Now, M30s (that is, straight-six motors as found in the likes of the E28 5 Series, E24 6 Series and so on) have been swapped into E30s many times before, so there was a wealth of information available. What Matthew had to do was figure how to tailor the swap to his own unique requirements. After much consideration and research, he opted for an M30B34 block – for strength – with an M30B35 head and #Getrag 260/6 transmission. That was the base spec. Then the fun could begin.

    The block was bored out to take 94mm Wiseco pistons, increasing displacement to 3.6-litres, while the crankshaft was balanced and the head received all sorts of handcrafted custom work. A Rapid Spool Industries exhaust manifold allowed the fitment of that all-important turbo (originally a Holset HX40, now upgraded to a Borg Warner EFR 7670), and naturally the fuelling and management were beefed up to suit. A trick exhaust system soon followed, as did a Volvo intercooler, some more appropriate cams, and upgrades to the valvetrain. Piece by piece, Matthew’s masterpiece was falling into place. On a conservative tune and at just 13.8psi, the M30 was making 450hp – which certainly helped with those corruptive power cravings.

    So, the engine box was firmly ticked. Still a lot of other things to sort though, weren’t there? “I tried several different combinations of springs and dampers,” says Matthew.

    “Ultimately I used autocross and mountain roads to dial in my suspension; my current configuration consists of Bilstein Sport struts and shocks, H&R J-spec front springs, GE adjustable rear perches and springs, reinforced rear shock mounts, Vorshlag front camber plates, drop hats, and Treehouse Racing control arm bushings. I swapped in an E36 steering rack and, of course, replaced both front hub assemblies. For the rear subframe I installed the AKG 75D 12mm offset frame, diff mount bushings and trailing arm bushings.”

    Okay, so the thing works well now. But it needs to look good. What next? Aha, the body! “When I began fixing the bodywork issues, I ended up with five different colours on the car,” he laughs. “I couldn’t afford a traditional paint job due to being a student, and I still had a huge list of maintenance and repairs to tackle, so the idea of painting it myself in flat military green was very appealing. It had an aggressive feel to it, and allowed me to easily change and add body panels as needed. It also made all the trim work that much easier, because subdued black and flat green are perfectly paired!

    “The entire attitude of the car followed the suspension setup and colour choice, although modifications such as the Kamotors arch flares were a product of necessity – especially with 8”-wide wheels and 245-section tyres on the rear – that just happened to enhance the overall demeanour of the car.” That Foha three-piece spoiler was certainly a lucky find too, it complements the hammered-together-by- The-A-Team vibe perfectly.

    Of course, it’s no good having a car that goes like a train, handles like a sticky panther, and looks like a militaristic warlord if you don’t actually have anywhere to sit.

    That rain-saturated tan leather trim had to go. “The interior of the car was in a horrible state of decay and disrepair,” Matthew grimaces. “When I replaced the battery tray, I took the opportunity to swap the dash with a crack-free one; I then followed that with converting the interior to black since I wasn’t a fan of the tan anyway! Through the forums I made contact with Kevin Chinn of Creative Options to discuss an upholstery kit, and after several conversations I decided on microsuede centres on the seats with vinyl bolsters for ease of maintenance. The seams were done with factory-style French stitching in light Olive green.

    Before the seats went back in I dyed the carpet black, and so the weekend ended with me having stained and sore fingers but amazing upholstery!” When we ask Matthew what his favourite result of all this homegrown dabbling is, he’s quick to answer: it’s the engine bay. The functional, severe exterior just doesn’t prepare people for the sorted, shaved, shiny bay that hides under the bonnet, and it certainly raises eyebrows at shows. And raising eyebrows is what this car was built to do.

    All sorted, then? Job done? Oh, no – Matthew’s far from finished here. “My list of mods isn’t based on winning the lottery, it’s based on money over time,” he says. “I’ve slowly but surely built it to be what you see now, and as time goes on it will only improve. Stay tuned!” We certainly will. But in the meantime, Matthew, you’d better head off along that Parkway. There are childhood dreams there waiting to be fulfilled…
