i wouldnt use that turbo, its a waste of time and money especially considering you wont be able to find a manifold that is flanged for that turbo.....
Those cams will actually make you lose power on a turbo app... turbos need a shorter lift and longer duration to make their full potential and those all motor cams you have would not do any turbo justice....
and I think that even on stock fuel you would be ok to run about 6-7 psi on like a 50 trim t3t4 but that turbo will also give you plenty of room to upgrade later and it works beautifully on the LS....
Hope that helps
