why not drop in a supercharger? or just the engine from the gtp if it has low mils? should make a nice difference. my favorite gp’s are the 97-03 style, only because i think they look better stock then the stock newer style, but when modded, its totally different.yours is by far the nicest new style i have ever seen. looks real nice and real clean. i love the rims, sometimes rims look like they were made for a certain car, and your car/rim combo does just that.
