If I were you I'd just even the playing field and throw in a 5.8L...you can exceed 400hp no prob and with the weight of your car and the right gear you'll have no worries...any way you go is still cheaper than what he spent on the gto

PM FullAuto. He sells nitrous and is a site sponsor. He should tell you what the best kit is for your setup.

Your toast bro.....a 400 hp GTO is going to eat you alive....better go with that 150 shot.....and get drag radials......just my 2 cents
