i got a 07 gt mustang with a hp 67 mm turbo, spec stage 3 clutch, and a rod threw out of my stock engine on only seven pounds of boost. My car made 440hp and 500 fptq. From what i have read other turbos of equal size and boost as the hp dont pull as good numbers as mine did why is that. My car had 18000 miles when it blew and only 8000 with the turbo. That seems a little too soon to me. I am pretty hard on stuff, but i do keep everything maintained. So now i ordered a new block and rotating assembly rated up to 1000hp from livernois. I heard there stuff was pretty good anyone else heard. They are the most reasonably priced and they charge a thousand dollars to assembly the shortblock or you can order it in pieces and do it yourself. Has anyone done something like this project and how did it turn out. I should be pulling around 700hp on16psi.
