ok so you wanna go faster than 110, easy go to over kill and get a tuned pcm. Second, performance mods on that type of car can be done but i would advise it the most you can really do are things like; cold air intake, down pipe, cat-back exhaust, hv3 intake just to name a few. Now, if you really wanna spend the money you can go for a l32 swap which would involve ripping apart the top end of the engine and installing different heads and a supercharger along with different injectors. I do now some guys that have way too much money to throw around and have done cam, heads, and a turbo install, but they are going thru transmissions like every other week. To some it all up, if your going to mod your car keep it simple.
