I had to share this car with you all, very impressive work went into this Evo VI and it was almost all done by one chap named Clive over in the good ol UK. First off, everything except for the cage, the paint, and the engine mapping was done by Clive himself, who is an Aircraft Engineer by trade, so everything you see below, was done by him in his spare time at home.
I was checking out what was going on over at http://www.timeattackforums.com and I came across someone who saw this build-up thread over on a european Mitsu Evo forum. I mistakenly clicked this link and proceeded to lose around 2 hours of my life that I'll never get back, but it was sure worth it. The quality of work this guy has put into his Evo working in a really quite small shop in his home is nothing short of fabulous.
The car started out as just any track day Evo probably would have, but it got much more serious from there on in, with a lot of trick one off parts. First off is the engine build:
The engine was stripped down to the bare block and was fitted with a Tomei crank fully balanced, Arrow conrods and JE pistons which were all balanced within 0.1 grams of eachother.
Clive took an old busted out head and cut into bits to examine where material could be removed and where it needed to stay. Using this as a guide did some pretty extensive intake and exhaust porting. Here you can see the nicely ported exhaust outlets.
Ported intake manifold.
Along with a Norris/Shearer T04Z turbo kit, this motor pumps out more than 800hp in race tune. Wow.
Un-satisfied with the quality of the stock drivetrain components, Clive rebuilt the transfer case and front diff installing a Cusco RS unit.
Here is the real meat of the project. After analyzing how the stock diff worked and where its weaknesses were, Clive designed a new diff, this one more stout than the factory unit and able to accept a Cusco RS rebuilt diff out back where most of the power get channelled to the ground. The amount of machine time into just this one part is intense, really nicely designed and built peice!
Next up is the chassis and suspension:
Clive had the cage farmed out, but its a pretty intense cage so I don't blame him. Lots of bracing going to the a-pillars and b-pillars. The Evo chassis is pretty stiff from the factory apparently so he opted to not have the car seam welded, but c'mon, just look at that cage, its probably stiffer than.. ok lets not go there.
Pretty nice welds..
Check out the flocked dash, I definitely need to get that done for my car, first to cover up the old grey crappy plastic, second to cut down all the glare plastic dashes give off. Definitely rally-inspired here.
Sparco wheel and Recaro SPG keep this office business like. An inline fan was mounted for driver cooling, drawing air from near the a-pillar instead of the hot air leaving the engine bay.
Lightweight aluminum inner door skins, but check out that door handle, hardware store special, made out of wood and weighs near nothing.
Some serious stoppage power here. 6 piston monoblock calipers made for a Porsche GT2 weighing a good 1000-1500lbs heavier than this car. These aren't off a GT2 though, they are brand new from the dealer. Combined with some seriously massive 14" AP 2 peice discs, slowing the Evo down should be a breeze at any track, at any time, with ease. You can see the adaptor he fabbed up to fit the big brakes onto the Evo spindles.
Clive called up ze Germans at KW suspension and ordered up a set of KW's 2-way racing coilovers. Not being happy to leave well enough alone, he fabricated up some new USM's to get more caster out of the setup. The extra caster helps dial out some of the inherent understeer seen in Evo's apparently.
