My SBF is NOT producing that kind of power, but I can tell you that the SBF WILL fit easily. If he has lots of aluminum on the motor (heads, intake, water pump, flywheel, etc) the actual weight on the front axle will be less than with the OEM Datsun L6. The 5 speed he has will fit (T-5 or T-56), and the R200 Datsun differential with the ZX turbos halfshafts should hold up depending on what he is doing with the car, and the tires. Typical Z weights go from 2300-2700 depending on powerplant and model of Z (the earlier ones where on the lighter end of this range).
