Minissan and the Worldsfastestclown

Mike Guido’s gorgeous Nissan V6-powered, front-engined, rear wheel drive Mini kicks both ass and arse.

The wheelbase and overall size remain within the original Mini foorprint, although the driver more or less sits in the back seat.

 

The quality of this Mini really is very high, and is matched by its fearsome but usable performance. A top mad Mini.

 

Mike Guido is on the mad side of the modified-Mini world, but is in other ways very sane. He thinks that tobacco and drinks company executives are little better than murderers, as they market lethal drugs to children. His logic is inescapable: consider the real purpose of alcopops. In response, he created an anti-drug campaign featuring The World’s Fastest Clown. As the Clown, he raced a factory 240SX for Nissan, in full clown make-up and a fireproof clown suit. He says that gave him a real edge on the track: if he bumped somebody from behind and they looked in their mirror to see a clown grinning at them, the momentary loss of concentration was all Mike needed to get past.

The mad racing clown also put on an effective anti-drug show for schoolchildren. As he’s mad but cool, he got through to them where advice from boring and uncool parents and teachers doesn’t, and he has probably saved quite a few young people from unpleasant but profitable deaths.

Nissan pulled out of racing, and the Clown discovered an innovative American budget race series where you can only spend $2000 on your car. Minissan was originally intended for this budget race series, but instead evolved into a show car that is used to attract attention to the Clown’s let’s-not-kill-children message.

 

Minissan is extraordinarily well-mannered and obedient, even when deliberately provoked by a bootful of throttle halfway round a corner.

 

Four years and 4000 hours later, here it is. The shell is from 1962, and is the mortal remains of Mike’s first Mini. He has in the past persuaded A-series engines to kick out remarkable power, but that’s hard work. A scrapyard Nissan V6 with a cam and a Nitrous bottle costs peanuts – about the same as a week’s holiday in Florida. Which Mike doesn’t need as he lives in Florida anyway.

Front wheel drive wasn’t really an option for this car. Serious power means that weight shifts to the back, so you mostly get smoke and noise rather tjhan rapid acceleration. A Nissan 240SX provided the necessary rear axle.

The front end geometry and suspension of Minissan remains basically Mini, but Mike had to learn much steering tech to get the right rack height. He used a standard RHD Mini steering rack, mounted low. Rack height is critical in any car, and getting it wrong results in bump-steer and vicious steering kick. The car was originally left hand drive, but that didn’t work with the new mechanicals. He even got the Ackerman angle right, which is the degree to which the inner front wheel steers more than the outer front wheel when cornering. That angle is not critically important as it mostly means minor tyre scrub when parking, but it’s revealing that he took the trouble to research it and sort it out.

The area of hole in the bootlid matches the area of the cooling surface of the radiator. With the fan at full blast, the coolant temperature drops like a stone.

 

 

 

 

 

 

 

Mike was concerned that cooling a big V6 would be a problem, but the vast radiator and powerful fan are extremely effective even in Florida temperatures.

 

 

 

 

 

 

 

Whirly exposed cam pulleys are rather fun. The engine is only a scrapyard pull-out, but looks better than most brand-new crate engines.

The back end of Minissan took a lot of sorting out. Minissan’s rear end is the independent diff, shafts and subframe from a Nissan 240SX, narrowed by 12”. The half-shafts were each chopped by 6”: they’re so short that the rubber boots are touching. The rear suspension struts are 240SX front strut cartridges modified to work as rear struts, and the front shock absorbers are from a Yamaha R1 bike. The springs are a massive 550lbs all round, so it’s weird that Minissan feels so drivable. When power is applied, the back squats for more grip. Front-to-back weight distribution is a virtually perfect 53% front, 48% back.

With a mid-front mounted V6 and independent rear wheel drive, the original monocoque structure of the Mini was mostly redundant, and its contribution to rigidity was replaced/enhanced by a rollcage/spaceframe chassis that provided mountings for everything, which was constructed in and around the Mini shell. It remains a steel Mini and some of the shell is still structurally useful. The rollcage passes through the body in several places. As much of the original Mini was used as possible – it’s still a Mini rather than a plastic lookalike shell on a rollcage. The remaining inner wings still feature spot-welds from 1962, deliberately left original and imperfect to make the point.

If you looked in your race car mirrors and saw this, you’d definitely make a mistake on the next corner.

 

 

 

 

 

 

Interior featured about a million stainless steel screws, all lovingly and individually polished by Mike’s wife Rhonnie.

 

 

 

 

 

 

The attention to detail is sublime. Whenever Minissan is entered for a show, it wins.

 

 

 

 

 

 

The detailing is obsessive. Each of the welds that passes through the Mini shell was ground, sanded, wet’n’dried, guide-coated, primed, wet-sanded and finally covered in rich red paint.

The fat wheel arches and other body panels are scratch built. That meant mentally creating the shapes, then fabricating them in 3D, then perfecting them, then taking moulds and making the panels.

Cooling required attention. The boot is the worst place on a car to put a radiator, but it was the only space available. The bootlid has more holes in it than global warming theories, the radiator is vast and the electric cooling fan is 17” in diameter. It’s very effective, taking ten seconds to clear most of the heat out of the radiator at full blast.

These are the original inner wings from 1962. They’ve been left in place just to make the point that there is still a real Mini involved here.

 

 

 

 

 

 

Another piece of stainless glitz, but like most of Minissan’s shiny bits, it’s there for a purpose: paint doesn’t respond well to exhaust blast from sidepipes.

 

 

 

 

 

 

Looking up underneath the car on a hoist, you can see the bodywork has been cut away to provide room for the gearbox, exhaust and coolant pipes. Exposed coolant pipes like this provide a useful extra cooling function.

 

The car all worked straight out of the box, a testament to the five ‘P’s. (Proper Planning Prevents Piss-Poor Performance.) There’s some room for tuning with suspension and geometry settings, but only in detail.

Even though he’d just spent 4000 hours perfecting Minissan, Guido threw me the keys. The clutch is an on-off switch, but apart from that the car is a pussycat. The steering is light and sensitive, the throttle is progressive, and the handling for such a short and powerful car is sublime. I punched it halfway round a corner to see what would happen, really invited it to bite me – but it just scrabbled very briefly, grabbed its grip again and spat me out of the corner pointing the right way, no bother.

 

Front suspension remains mostly Mini – after all, it works just fine, so why change it?

 

 

 

 

 

 

 

 

 

Nissan half-shafts have been shortened dramatically to allow fat wheels within the extended Mini bodyshell. Geometry is tricky but sorted.

 

 

 

 

 

 

 

The empty engine bay makes it clear how much Mini bodywork has been retained. The V6 engine is only 3 cylinders long, so much of the original bulkhead remains.

 

 

 

 

 

 

 

The engine has since been tuned, and the punch is even more explosive now, with a nice mix of torquey V6 3-litre grunt and some useful bhp when the engine starts roaring. Power is something like 225bhp, with another 150bhp nitrous injection system available in case of boredom. The cam is mildly rude, as is the exhaust note, but the car remains genuinely streetable. The engine is secondhand from a junkyard, and imagination rather than dosh was applied. The intake was modified from a late 1980s injected Nissan pickup, with a Holley spacer plate welded to it.

Mike’s wife Rhonnie has been behind him all the way, including making the carpets, hand-polishing several hundred little stainless steel screws, and putting up with her kitchen and house being crammed full of Minissan bits for several years: so she absolutely deserves the shorty Mini she’s been promised.

The trouble with all this beautifully finished custom stainless steel and perfectly painted bits and pieces is that you can’t leave them lying around in a grubby garage – so Mike and Rhonnie had to use their house for storage instead.

 

 

 

 

 

 

 

Going back to the build, the substantial floor beams and door bars contribute to the rigidity of the rollcage, which is integral with the Mini’s bodywork.

 

 

 

 

 

 

 

The 300ZX engine was in good shape when bought from the scrapyard, so it was checked, cleaned, painted and prepped for use in the Mini with custom coolant hoses and pipes.

 

 

 

 

 

 

 

 

 

There was no hope of saving much of the Mini’s inner wings, so the tubular brace bars locate the front subframe solidly.

 

 

 

 

 

 

 

 

 

 

 

The mountings required for Mini trailing arms and those for a Nissan central diff, struts and control arms couldn’t be more different. An entirely new tubular structure had to be designed and fabricated.

 

 

Finally, this and the next pic capture the effort that goes into building a car to this standard. Every weld in this car is finished to this standard.
