UPDATE: With just minor tuning this LS1 power GTO with stock ported heads & mild cam made 645hp & 651 ft/lbs of torque at the rear wheels at only 5lbs of boost! We still retained it's streetability with reaching full boost below 3500rpms. Thanks to everyone that helped with this project.


This '04 GTO is getting a custom turbo kit featuring the Precision 76GTS turbo.  We are looking for HP numbers in the 600's at the rear tires and 1/4 ET's in the 10's!  This is quite an accomplishment in the 4,000# Daily Driver!
