  • Welcome to Forever Pontiac

    We are a community of Pontiac enthusiasts. The purpose of our community is to keep alive the Pontiac spirit by sharing (or showing off) our cars, discussing Pontiac, helping each other work on our cars and find information, plus attend various meets/shows/etc... To aid discussion, sharing, event planning and selling of parts/cars/anything, we have various parts of the website to aid this from Forums to an online Garage to Classifieds to even a Document Download Repository. You can find links to these in our navigation above based on what each section helps with (discussion, local events, learning, etc...).

    We invite you to contribute, find help or just view some of our member's amazing cars! Don't forget, we also have great contests from time to time (like our Pontiac of the Month and yearly calendar contest) and our Pontiac This OR That, a fun game where you choose the best of two randomly selected Pontiacs from our online garage.

    We look forward to seeing you around!

I have a 2008 grand prix "base". even though its base, the performance made me a fan. its true what they say about grand prix's as being clutch in the heat of the moment. i really want to know how i can make my N/A 3.8 a car that will grow with me, by increasing the performance. i saw some one mention a top swap, to a super charger..............realistically improving on the guild work would be my first choice, headers and intake. but im not to shabby with stronger injectors or spark plugs. What are some things i can do as an in depth stage 1 step up.

The first question I ask anyone who wants to make performance modifications is how much can your afford to spend and how fast do you want to go? What is your budget?

Injector changes, a cold air kit and free flowing air filter, a bigger throttle body, headers, a PCM flash tuner, and catback exhaust systems will all help your 3800 gain some ponies on the relative cheap.

If money is not too big an object, you could ditch the 3.8L altoghether and install a suped-up LS4 like what was in the GXPs originally. Something tells me that is not in the cards. That would also require some tranny, suspension, PCM, and brake upgrades too. Still it would be an awesome sleeper! Especially for a base FWD car.

There are companies that offer stage kits, clearly catalogs like Summit Racing and Jegs carry performance parts for the 3800 Series I, II, and III engines. Supercharger, turbocharter and nitrous kits are also available.

3800performanceparts.com, zzperformance.com/3800 come to find for initial kits.

Abbott Racing has Stage I racing heads for the 3800.

Ray Barton makes performance/racing pistons for the 3800.

Again, how deep are your pockets? My recommendation is do your homework. Pour over YouTube videos and how-to / DIY performance articles for the 3800 and the GP. Get feedback on what parts work and don't work, how expensive they are, where to get them, and make your budget from there. It's a little more time consuming but I think you will find you will spend less money in the end.
