there are plenty of fast non turbo/supercharged cars available for cheap. take a pontiac fiero for instance. just the gt fastback models. most others were piles of crap. the 1988 was extremely good at handling corners. the car came stock from the factory with a 2.8L V6, holley intake, multi-port fuel injection, mini tunnel ram intake manifold, ram-air induction, dual exhaust, limited slip rear end, muncie five speed transmission (ask your dad about the muncie tranny. bullet proof. very strong) four wheel vented disc brakes. the list goes on. there are several others new and old that are great cars that get overlooked for some reason or another but they do exist.
hope this helps
