Trust33 ps means "power stroke" its approximately 400hp rated (thats what i have been told). The turbo come with all accessories you need to fit it to your gtst, gaskets, lines, elbow etc... I have the turbo and have standard bottom end, and so does my mate. He runs 1.3 bar all day every day, i will run around 1 bar (just to keep things safe). At 1 bar i am expecing around 240 rwkw. I think this turbo can run up to 300rwkw but u will need forged internals and a lot of boost, cams etc... Trust33 why rebuild the engine if you dont need to, just wait till it dies.
