mk3 jetta best "race car" vw has ever made, and the best motor to do anything to is a 12v vr6. turbo cars runnin 9.5's(brian k) and puttin down over 700whp (chris green) and all motor vr6's runnin 11.93 (anthony d) with only 200whp. you dont see any 24v doing that or any 1.8t comming close to a 9.5 1/4 mile. oh and all the real vw race cars are pretty much mk3 chasis.
