you aren't going to make your teg really fast by just bolt ons. if you want to be fast, you're gonna have to go forced induction, or some hardcore n/a engine work. if you want to be somewhat faster and have the money, i'd recommend intake, header, high flow cat, catback exhaust, and ITR headwork (cams, pistons, ect). however, may i suggest you do [quality] suspension work first. im more satisfied with my suspension mods than the bolt ons i have.

please read about your car first though. if you are unable to do all of these things yourself (read: NOT pay someone to do it), then you shouldnt do it.
