Pontiac Grand Prix Forum : “how do i make it fatser, what performance parts would be the best”
You can gain up to 60HP by tuning the computer, getting a cold air intake, and a higher-flowing bolt-on exhaust. Try talking to GM parts department about any factory performance parts first.
www.clubgp.com is possibly the best resource for you to find information about modding. Sign up for an account
and go over to the l32 engine section.
first off, fuck factory performance.
its twice as expensive, and it'll be the same stuff as other brand name stuff.
start with an intake, full exhaust, or at least a catback, lighter wheels, if you really want to make power, get a turbo, or if you can, bolt on a supercharger from the SC models....
