Yea it should work both ways if u cant take it dont dish it out. U shouldnt down somebodys ride and say theyre stupid an such an then expect them to respond back nicely an respectfully an say thanks for the help. The LS4 conversion was just an idea i heard of i figured if i can find a LS4 motor, tranny, an so on for a real good deal it would be worth trying but the gtp motor and trannys i know are a hell of alot cheaper. I like being different i like power but im not strictly trying the conversion just for power. It can make it faster i know but it is also very different compared to everything else out there that ppl have done to their gps an from the car shows ive been too i noticed being different stands out alot an can help u at car shows. If I did the LS4 conversion with no additional mods could i hit 13's in the 1/4?? I know the gxps an ss run low 14's in the 1/4 but i heard the older model gps are a lil lighter.
