00 GTP perf questions

imtheoneandonlyD · 03-09-2006, 12:29 AM

My sister has a 2000 GTP with the 3.8 v6. She is looking to make it a little faster. I dont know much about these cars but since hers is supercharged i was thinkin maybe a pulley would help? Im not sure where to start here so any tips would be great.

www.pfyc.com has lots of performance mods for grand prix's. Great website. K&N cone filters and pullies are common gtp mods.

I'd start with a 3.4 supercharger pulley. It is the best street mod for the cost. Then a CAI or FWI. From there depending on how much money you are willing to spend a re-programmed PCM and exhaust mods.

The most popular PCM mod from DHP was reduced from $214 to $99.

Thanks for the replies guys, i know she isnt looking to have a rocket. Just get a little more power out of it. Ill look into the pulleys first, as i know just a pulley can do alot for a SC.

Amen to that! Be sure to drop down at least one range colder on the spark plugs for the 3.4 pulley. Autolite copper core 605 will do the trick. Good luck!
