Modding a 2002 GP SE
Modding a Pontiac Grand Prix
Hi everybody, my name is Pat and I'm a 17 year old driving a 2002 Pontiac Grand Prix SE. I have about $2500 saved up, and I want to get to work on improving my car's performance. It has a 3.1L V-6 in it, with an automatic tranny, and everything is stock. I'd really like to boost my performance without resorted to N2O or anything like that. I've done a decent amount of car work, and my Dad's done a lot,so I can probably do most of the standard modifications to my car that I want to. I plan to: 1. Buy and install either a supercharger or turbocharger. I'm not sure which I'd rather have, because I have to pay for gas myself. 2. Stiffen the chassis 3. Bore the cylinders and install some larger piston heads. 4. Replace litttle things like air filters and stuff like that. 5. Eventually (way in the future), replace the auto transmission with a manual. It probably would be cheaper and less of a hassle to just leave it, but I like driving a stick and my dad says it would be good for my to get comfortable doing some major work. My main question is, which should I start on first to improve my horspower, and if anybody else could recommend some other modifications. Thanks a lot, Pat

Re: Modding a 2002 GP SE
Instead of installing a supercgarger in your car it would be alot easier to sell it and buy a GTP....The intake,exhaust,transmission,ecu and more is different.Assuming you sell your car and get book value for it,. you can take that money plus $1000 or so more you can get the same year GTP..That car stock is pretty quick. With another $1500 it will become a rocket...Probobly alot faster than if you mod your SE

P.S...also my car with the superchager gets 1MPG less, local and HWY, than a non supercharged motor, if i drive it like a Grandma. It does have the potential to get very poor milage if i step on it.

Re: Modding a 2002 GP SE
Even a GT should do you well if you can't find a GTP for the right price. The NA 3800 is no sloutch and I get about 20-22 with mainly city miles.
Not bad at all.
