ok, i have some experience with the 1g coupes...if you have a V6, the engine is a 6g72. if you have a 4 cylinder, you have a 420A. the 420A is the same engine that is found in the dodge neon, and there is alot of aftermarket support for those...a friend of mine has a 95 sebring, which is basically the same as your car, and he is making around 400hp with a built 420A.

if you have the V6, there are companies that cater to performance for them...its the same engine that is in my stratus, and that came in the stealths and mitsubishi 3000GTs.

for wheels, check around online, you can get a set of low priced wheels that will still look good.
