Beat the heck out of the thing. I think I started flooring mine at 200 miles and haven't had problem now with 7k on it. The more you baby it, the slower it will be down the road. :-D

But as far as the races go, 350z > Crossfire = Prelude > Jetta.

Assuming all are stock. If the Jetta just has a chip and is a 1.8t, he will be pushing 210-220 whp depending on the tune and year. So he will win, and the H22 (Prelude) responds to mods quite nicely. Just some food for thought.
