Its cool bro, I get my share of critism from the GP community for looking the way she does. I cant wait til our national drag days to blow people away.
Currently Im running ~18 lbs of boost through an Eaton M90. Im at a bottleneck until I get heads or cam to flow the exhaust. Same Supercharger as whats on Lightnings and australian Holdens. There are many enthusiasts out there, some of the larger groups are at clubgp.com (19,000 users) and 3800tech.com. The GP is a 3.8 V6 240HP stock, and wider is better ;) There are some/few GP's in the 10's sponsored vehicles by zzperformance.com or intense-racing.com. Now you have all the info on GPs :cool:

Personally, Ive stayed with the GP because my second car was a 90 GP. She died, great car. Then I bought a 97 GTP, has 130,000 miles and still strong. And I wanted a newer GP, so I got the silver 98 GTP with 56,000 miles. The GP is a versitile sedan, Id even say sleeper in the right hands.
I will say tho, it is expensive to work on a car that has a lower demand/supply of aftermarket dealers/suppliers. headers+ full exhaust=1g, hood 1g, koni struts & springs= 1g, rims and skins=1g, trans 2g, intercooler =1g, damn its rough being a gangsta

OK, Im done with my hijack
