Ricksta from personal experience don't invest a dime on your stock gts motor. Thats a 5sfe peice of shit. No offense ofcoarse. I use to have 2 of those motors. By the time u turbo that motor you will probably spend about 2k if you do it right. I can offer you everything that you need to swap your car with a 3sgte to make it fast and reliable. 5sfte which is code for your motor turbo could probably only handle about 6 psi before it gets dangerous. stock 3sgte can handle 12psi safely and you will be making about 200hp to the wheels. I got a clip for sale 2300 already shipped here. I know a shop that will swap it in for a reasonable price. Reason why I'm selling my clip instead of swapping is because I need the money for some shit i got into.
