there's a couple you can do to get some extra zip for pretty cheap. exhaust, intake, underdrive pulley, headers, then they start getting more expensive. cams, turbo or supercharger. also, you can mod the suspension for better handling aka. springs, shocks. get better tires and wider rims (of course light as you can) for traction. if your a psycho you can get a nitrous oxide system ( i don't suggest ) the list really goes on, but there's also a ton of asthetic stuff you can do too, but that's not what you asked about so...i won't go there.
