well you could put a turbo but that's alot of money.... how bout a cold air intake, exhaust maybe. a chip set. with the cold air intake and average chip set your looking at about 400. that's bout 30 - 40 for the intake and 200 - 300 for the chips and when you put chips on you have to get your computer reset and that's about, depending on where you go, 60 - 100. the intake might give you 5 - 10 more horsepower. the chips any where from 30 - 60. but getting our computer reset can also add power. doin all this you might want to get a new tachometer cause your redline might change.
