    Five star. This ballistic B5 is packing 500bhp so has the go to back up all that show… Words Davy Lewis Photography AJ Walker. AUDI RS4 500hp B5.

    There’s something about an original that gets under your skin. The first version of something – whether it’s a trainer, a film or a car is somehow special. It’s odd when you think about it, as quite often, the first version of something isn’t quite right. It’s not until it’s refreshed and V2 is releases that everything comes together. This may be true of smart phones, TVs and other tech gadgets, but with cars? I’m not so sure.

    On the one hand, you can’t deny that each time Audi releases a new version of a well-loved model, it will be bristling with technology. It’ll be more powerful, more reliable and generally better all round. Yet many of us still hanker after the original. Nowhere is this more so than with the RS4.

    The original B5 was released in 2000 and immediately made a statement. Here was a 375bhp, four-wheel drive estate car that could outflank a Porsche. It boasted a Cosworth-tuned, twin-turbo V6, fantastic blistered wheel arches and a presence that oozed understated aggression – something #Audi does so well.

    But here’s the thing: the B5 RS4 is now 17 years old. Two further generation of RS4 have been released, with another, the B9, due to drop later this year. But, for many, the original B5 is still the one.

    Forget the fact that it’s been eclipsed dynamically by the newer models. Ignore the issues with reliability inherent in a highly-tuned-from-the-factory machine like this. Put to the back of your mind the horror stories you’ll hear from B5 fans who have almost bankrupted themselves attempting to keep their pride and joy on the road (times this by ten if you’ve tuned it) and focus on the good bits. Of which there are many. Which is why there’s such a healthy appetite for these things.

    So when serial Audi tuner, Julian Loose and our man, Adam Walker, spotted this in-your-face RS4 in Austria, I was keen to find out more.

    On the face it, this is ‘just’ another RS4 with a fancy wrap. It has a taste of the Jon Olsson about it– he of the extreme RS6 and R8 Gumball fame. However a bit more investigation revealed that this was a proper build, featuring a 500bhp engine, tuned chassis and more.

    Let’s kick off with that engine. The twin-turbo V6 needs no introduction. The 2.7-litre unit came with a factory fettled 375bhp and went very well indeed. But, as the years pass, this highly-tuned lump needs plenty of TLC to keep it running as it should. It’s a complete arse to work on and needs to be dropped for many, even routine jobs, which is why it can end up costing a small fortune in labour rates alone. Plus there are numerous documented issues that will occur at some stage from corroded pipework to blown turbos.

    So, it you’re really going to do it, you may as well get stuck in and go for more power right from the off – and make sure you uprate all the necessary parts in one hit. That way, you (hopefully) won’t be spending more time in the garage than on the road.

    The owner, Ilkka, has gone for a tried and tested setup of RS6 hybrid turbos to provide the boost. There are 630cc injectors and a TFSI coil conversion, plus Wagner intercoolers, a cold air intake and custom made exhaust with the cats removed – a sure fire recipe for big fun. With around 500bhp on tap performance is best described as brisk.

    The whooshing of those twin-turbos, combined with the snarl from that unrestricted exhaust means this thing emits the kind of V6 howl that makes you smile. It’s a special B5-ness that you simply can’t find anywhere else.

    The stock transmission copes admirably with the extra grunt and the tough sixspeed box takes it all in its stride. Again the manual gear lever is part of the reason so many people love these things.

    With significantly more power than when it left the factory and with the ravages of time, the chassis needed updating to cope. A full complement of poly bushes was fitted, to remove that saggy, vague feeling that occurs when stock bushes wear out.

    Again it’s a pain in the ass job to complete, but it makes a big difference, especially on older Audis. With less play in the suspension and steering components, the B5 feels tighter and more responsive. To allow the suspension to be finetuned, a set of KW Variant 3s were ordered.

    These multi-adjustable units allow full control over bump and rebound, to provide a sporty, yet forgiving feel. The geometry has been professionally setup to give this RS4 a more dialled feel, with far more adjustablity than the neutral, understeer focused stock set up.

    The final upgrade for the chassis is a set of brakes nicked off a Porsche. These meaty calipers were designed to stop a 170+mph sportscar, so do a fine job on the RS4 teamed up with ECS Tuning discs and Ferodo DS2500 pads.

    Styling wise Audi got it right first time and there’s no need to add bits, aside from the odd splitter or maybe vent if you’re into that sort of thing. So this B5 remains stock, aside from a wrap. Now, it’s not going to be to all tastes, but Ilkka wanted something to make the car stand out at events and the Jon Olsson-inspired camo wrap certainly ticks that box.

    One thing that had to be bang on the money was the wheels. The 3-piece, multispoke Rotiforms fill the wide arches very nicely – and at a girthy 10.5-inches, they should. Some work was required to get them to fit right, but they look great.

    Inside, the stock seats have been replaced with some of the best in the business, Recaro Pole Positions. These fixed back efforts not only look great but also save weight. The GT-inspired interior is completed with a suede steering wheel and gear knob.

    So there we have it – another wellfinished RS4 B5 that reminds us how much love there is for these things.

    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…

    Ultimately I used autocross and mountain roads to dial in my suspension.
