Uh, where or when was theere ever a single turbo 300zx?

As for the location of the turbo. A new braket to hold a larger radiator will have to be fabricated to move the radiator and AC condensor core foward by about 2-3 inches. Other than that a single turbo could either be set directly up front, behind the radiator or up top like a conventional setup, however in that case, the exhaust manifold would have to be quite lengthy...resulting in more torque.

If i do it, it will be hand made by me and a little outsourced labor by a engine building company a used to manage. And you are right, 5psi would yeild a good 40-50wtq with the correct selection of compressor wheel and exhaust housing. What are you guys thinking about tuning it with. (Wondering if CROME will work to cut costs...?)
