I know of one The NA 20v I5 in Alex Erisoty's 90q 20v rally car sports 275hp. Very trick Audi Sport piece though. 12.5:1 cr means race fuel only. Revs to 8500rpm, no low end. Many parts made from unobtanium. Practical? No. Rip your head off quick? Yes with slicks and a 4.86 gearset the ride I got was a blinder. Alex has been doing really well this year for a novice season Neil
