Hey guys, I just found a local hook-up on a used Greddy manifold and downpipe for my D series (from the 15G kit I believe)... problem is the turbo is shot. Does anyone know if any other turbo will fit in there? He said the flange might be the same as a 300zx TT turbo... that just sounds strange. If not, I'll just stick with a 15G, I only want to run ~5 psi. 140k mi, and I need it to hold another 2 years at least.

As far as fuel management is concerned, should I be ok just running an FMU at 5 psi? If so, what ratio would be good? 12:1, 8:1?

Last thing about intercoolers: They say running without an I/C increases chance of detonation - is this an issue at 5 psi?
