i just got full ownership of the grand prix, since my parents bought a GMC, so i installed a system, but now i despretly need more power. Does any1 know what kind of supercharger i can put on a 99 Grand Prix GT?? or maybe i was thinking about a turo kit, which is better anyway? Ive been duin some reserch and i found that turbo's are more expensive, are they better, and are they worth the money? What other cheap mods can i perform to find some power while i save up for a turbo/supercharger???

If any one is looking for some subs and does not kno which one to buy i really recomend Kicker!!! They are really worth the money, i have 2 12inch solo barics and they set of car alarms!!! I found a good site that gives u one free when u buy one soo thats a great deal!!! if it wasnt for that i wouldnt be able to afford it since im only 17.

add an exahust to the car try flowmaster 40 series it will really set off the car and its fairly cheap compared to a supercharger or turbo. remember when you do it delete the u-bend and resenator! it will give you a deep sound. :D

will it pass the emissions test???? do you think its actually goana help?? ima consider it, i do want my car to sound a little more agessive and mean! i think i will defonitly get it with time, this week im going to get a large cheak so i plan on spending it on my car. any idea of the price ranges??

don't Supercharge it....Turbo it, the L36s take to turbos VERY well....and turbo>SC

i was actually considering it, i cam across it online. Do you kno which one is better (supercharger vs turbo), and is it possible to have twin turbo??

Do you kno which one is better (supercharger vs turbo),

I personally think that turbos have more potential but there are the L67 guys who think that the supercharger is the best thing on the planet....I really think that GM would sell more cars if they would go turbo instead of SC...
