Homologation rules are the best. How do we know? Just look at the Volkswagen Rallye Golf.
Built to homologate the Golf for Group A rally, the Rallye model features VW’s Syncro four-wheel-drive system, wide box flares and, for good measure, a supercharged engine.
In total, only 5000 were ever made, all configured with left-hand drive and only available to those …
Oh yes.
These are awesome. For awhile they weren't even all that expensive. Wouldn't want one as a real car here, none of them came with A/C...
Super cool, but those wheels would come off that car immediately if I bought it. Yuck.
And is that an 8V head I see?
In reply to CyberEric :
Supercharged VWs were 8 valve engines, mostly seen in the States in Corrado G60s.
I had a G60 engine kicking around for a while. They had a bottom end like an Audi turbo 10v, with small crankpins and 136mm rods vs. the larger pins and 144mm rods of the naturally aspirated engines. (Someone told me it was basically a forged 1.7 crank) The pistons were necessarily heavy, but they also had a TON of space between the top ring and the top of the piston. VW shortened the rods so they could move the ring pack really, really far down for piston strength.
I don't know why they used the smaller rod journals. The rod bearings would be wiped down to the copper after 60k miles.
The real neat/interesting thing was that the G-lader was a blowthrough setup. The throttle body had a bypass built in to it that was linked to the throttle plate. Closed throttle meant the bypass was wide open and the bypass was closed at full throttle. That's what all that extra plumbing is for going back from the throttle body to the air inlet.
What I want to know is... is that an 020 or 02A transmission? Corrado G60s had the 02A. Golf Syncros had a rare all wheel drive version of the 020. The 02A was a lot stronger than the 020, but as long as the Tinkertoy and Lincoln Logs linkage was in good shape the 020 shifted a lot better IMO. Probably because it had little watch gears in it 
One of my unicorns. So hawt with birthing hips despite not being terribly rowdy in thw modern sense. In my dream garage on is parked right next to a Celica ST205. Yum.
Tim O'Neil wheeled the real thing back in the day and I think still has at least one tucked away at the rally school.
In reply to Pete. (l33t FS) :
Can't say that I've ever seen a g60 motor wipe out its rod bearings. I put well over 60k miles on mine without a single engine issue.
Other issues, but not a single engine issue
