Having built a full-on race car and a sleeper, Andreas
MASTER OF ALL TRADES Words Jeff Ruggles Photography Stefan Bau Having built a full-on race car and a sleeper, Andreas Schröter was determined to make his latest demo Mini tick all of the boxes. 44 MIM206.white_vtec.indd 44 11/1/12 11:06 AM VTEC MINI W e can try to avoid the subject as much as you like, but compromise is a traditional part of Mini ownership. Over the years we’ve seen Minis built for outright speed, endurance and even for comfort, but trying to combine all three is traditionally an automotive case of robbing Peter to pay Paul. If you really to want a Mini for every occasion, it seems the only solution is to own a yard full. If you’re a Mini fan you’ll surely appreciate and embrace such a scenario, but it doesn’t have always be this way. Just 45 MIM206.white_vtec.indd 45 11/1/12 11:07 AM VTEC MINI As purchased: Andreas’ father bought the donor car in 2008 as a 1275cc carburettor-fed Cooper. ask 33-year-old German Andreas Schröter. He’s the man behind a Mini that’s not only luxuriously appointed and dependable, but indecently fast too. So how does that work? Powered by Honda The answer centres around Honda’s legendary VTEC engine. Now if experience has told us anything, it’s that the venerable old A-Series is capable of punching well above its weight and then some. But to generate serious power figures, you have to spend serious money and really keep on top of the upkeep. On the other hand, Honda VTEC lumps can be good for 200bhp and will survive with only The extensive ICE includes a Rainbow fourchannel amp housed in a leather boot build. minimal maintenance. Little wonder it’s such a popular engine transplant choice. For Andreas, the combination between Mini and Honda was a natural one. A Mini was one of his first cars, and he started out his automotive career working for a Honda dealer. He subsequently set up GRacing in 2006, initially concentrating on Honda tuning but also specialising in Mini VTEC engine conversions. Located near Stuttgart, the firm is now the exclusive European dealer for US-based Honda transplant specialist Mini Tec. Previous demo vehicles have included a full-race spec monster and a sleeper, but the emphasis was different for this one. The 210bhp VTEC motor is mounted in a custom GRacing subframe from USA firm Mini Tec. “With this conversion we wanted to create a inconspicuous Mini Supersport car equipped with almost all luxury features possible,” explains Andreas. The basis for the project was a 1992 Mini Cooper. “My father bought it in 2008. It had only covered 37,500km and was in nearperfect condition,” says Andreas. “It’s also one of the last 1275 carburettor Coopers to be sold in Germany.” Nevertheless, the car still had a couple of corrosion issues to sort when it was taken off the road to begin the project. “All the rust was removed and the body completely restored, with only genuine panels used,” says Andreas. “The shell was painted in 46 MIM206.white_vtec.indd 46 11/1/12 11:07 AM VTEC MINI Audi Ibis White. After that, all cavities were treated with Mike Sanders rust prevention grease.” One of the biggest criticisms of many engine transplants is the need to extend the front end, spoiling the Mini’s proportions in the process. However, we’ve seen several VTECs squeezed into a standardlength roundnose in recent years, and Andreas’ creation is no exception. This isn’t just any old VTEC motor though. For starters it’s a 1797cc unit rather than the more common 1595cc, and a hot one at that. Imported from Japan, it’s the 200bhp B18C used in the JDM-spec Honda Integra Type R, giving a 10bhp advantage over European offerings. It’s been poly mounted in a GRacing subframe from Mini Tec, with a custom alloy welded inlet manifold, BMC Carbon Dynamic airbox and a high-performance alloy radiator carefully chosen to help it all fit in. There’s also a pair of beefy hybrid driveshafts, capable of handling up to 400bhp. Otherwise the engine and transmission are largely stock Honda fare, with the exception of a competition clutch and the lightest flywheel available. Combined with a special final drive to suit the Mini’s smaller wheels, the result is a response that Andreas describes as “phenomenal.” There’s also an extravagant custom 2.5-inch bore exhaust system, which can be used to change the car’s personality at the mere flick of a switch. The rear section features two massive silencers to keep the noise down, but these can be bypassed with a straightthrough pipe for, as Andreas puts it, “pure sound and horsepower.” The exhaust is also fitted with a race catalytic converter, meaning the Honda motor is now good for a plentiful 210bhp at 8200rpm. It’s not all high-revving fireworks though, as Andreas explains: “Just like the stock Mini engine, the Honda engine is also long stroke. This design and the VTEC system is why this engine produces 111lb.ft torque at only 1500rpm! Peak torque is 147lb.ft at 6500rpm.” Such power means a rapid 0-60 time of around five seconds on street tyres, and a claimed quarter-mile time of 12.8 seconds. Naturally, that means some pretty big anchors are need needed to slow the car down, and that exactly what it’s got. Wilwood four-pot callipers have been "We wanted to create a Mini with almost all luxury features possible...” 47 MIM206.white_vtec.indd 47 11/1/12 11:07 AM VTEC MINI teamed up with 9.5-inch vented and grooved discs, and there’s a Wilwood racing pedal box with adjustable bias too. Suspension-wise it’s also been suitably upgraded. The use of the Mini Tec subframe means it’s somewhat unfamiliar up front, with Rose-jointed lower wishbones, adjustable upper arms and AVO alloy coilovers with Faulkner springs instead of the usual rubber-sprung arrangement. Things are more recognisable at the rear, however, thanks to a standard subframe with Adjusta Rides, adjustable camber/track brackets and Gaz dampers. The complete package So it’s got the all the right bits, it’s staggeringly quick, and – thanks to the near-stock engine – it’s reliable too. But there’s more. Unlike with the vast majority of 200bhp Minis, Andreas isn’t going to get tinnitus or backache after a long drive. The interior may look sporty, but it’s crammed full of luxury and gadgets at the same time. Just open the door and the smell of leather makes it clear that this is no ordinary build. “All the leather is from my mother-inlaw,” Andreas explains. “She is the owner of an exclusive tailor shop, and said if wanted to build an exclusive car, I’d need to use the best leather available. It’s 100 per cent cowhide and naturally tanned. It’s absolutely untypical to use in a car because of the high price.” A particularly striking feature of the re-trimmed interior is its seats. “They are from a Mazda MX5, mounted low down so even tall people can find space inside,” says Andreas. The rear seats have also been ‘plumped’ and trimmed to match, while the dash rails and doorcards are leather too. In front of the driver are several Autometer gauges set in a custom carbon-fibre dash, while the passenger has the pleasure of a neatly trimmed glovebox with an oildamped, push-open lid. In here you’ll find a 12-volt power socket, USB connection and a video-in port. Other gadgets include a dash illumination kit, electric windows, remote central locking, alarm and immobiliser, wiper delay kit and even a chime for when you’ve left the lights on. In addition, the ignition key has been cut from an original blank Honda item for that factory-built feel. And as if that wasn’t enough for the inside, there’s the impressive ICE install too. The head unit is a Clarion double-DIN multimedia station with DVD, touch screen, navigation and iPhone controls. Audio signals are feed to a Rainbow iPaul amp, known for it’s crystal-clear quality, which in turn powers a set of three-way Rainbow components up front in custom speaker builds. There’s another pair of Rainbow speakers in the rear shelf, plus a JL six-inch subwoofer under the seat for tight bass. “The hi-fi system is one of the best on the market,” explains Andreas. “Thanks to excessive sound deadening mats and insulation there are no vibrations or rattles, only pure sound.” Classy custom "The leather is absolutely untypical to use in a car..." Outside, the car has been given a similarly sporty but classy makeover. Mini mainstays like the chrome bumpers and spot lights remain, but they’ve been joined by several modern touches. At the rear, for instance, is a new VW Beetle reversing lamp, which has been frenched-in to the rear valence and fitted with a red bulb to create a stealthy fog light. The white paint has also been given a contemporary twist with carbon-effect vinyl wrap, cleverly used to create a neat visa-versa stripe effect on the roof and 48 MIM206.white_vtec.indd 48 11/1/12 11:07 AM VTEC MINI FINISHED SPEC BODY 1992 Mini Cooper, completely restored and rust proofed, battery box removed to clear exhaust, VW new Beetle rear fog lamp, air vents in bonnet and front panel, Lamm arches and sideskirts, Monza fuel cap, two spotlights, stainless steel wipers washer jets and blanking holes, chrome numberplate light, clear rear lenses, custom GRacing badge.

TRANSMISSION Honda Integra Type R S80 five speed, Torsen LSD and special final drive, Fidanza lightweight bonnet. The mirrors have come in for the wrap treatment too, as have the beefy Lamm arches and sideskirts. From the outside, it’s clearly no standard Mini, but it still has that inconspicuous look that Andreas wanted. Besides, the only real giveaway to the VTEC conversion is the Type R badge on the bootlid. Fully approved The build was completed in under six months, just in time for the IMM in Hungary.

I forgot to plug in the ECU!” Then came the task of getting the car road legal. Plans for conversions like this in the UK are often shelved due to concerns surrounding the BIVA test, but it’s even harder in Germany. Getting any Mini to meet strict TÜV regulations is tricky, but it’s even harder when you’ve got a Honda engine transplant to deal with. However, Andreas has it covered: “Since 2006 we’ve worked hard to get all our builds TÜV approved,” he says. “Therefore we’ve spent INTERIOR Mazda MX5 seats re-trimmed in leather with red two-thread seam, seat and embroidered GRacing logos, rear seats plumped and timed to match, leather dash rails and doorcards, Raid suede steering wheel and gear knob, carbon handles, custom carbon style dash with Autometer gauges, exhaust bypass switch, oildamped glovebox with LED light, 12-volt power outlet, wiper delay kit, dash illumination kit, lights-on chime, electric power window, central locking, keyless entry, car alarm and immobiliser.

At the moment we are in the midway through getting our Minis also street legal in Switzerland, which will also cover Austria, Italy and more.” Andreas has since used this car for his wedding – apparently breaking the dual horn from excessive use in process – while future plans include fitting power steering. However, it’s likely to be sold next year to make space for the next GRacing demonstrator. Interested? It won’t come cheap, but could well be the only Mini you’ll ever need... 49 MIM206.white_vtec.indd 49 11/1/12 11:07 AM
