the factory engine torque is 270lbft but the rear wheel torque (as was measured by the fx50 dyno or a 370z dyno) would be less in a Z ~230 ish.... remember a stock engine torque rating for the fx50 is 369lbft.... or about 100lbft more at the engine then a Z.... Even if this translates to only 70lbft at rear wheels (as evident by the dyno) that is a substantial built in margin. Thats why I posted an actual dyno sheet of the rw torque rather then the official values, but even so the engineerd cussion would be above the fx50's value...380-390lbft at the engine would be a very conservative guess ie about 320rwtq... ok last post for a very long time.

EDIT: Interestingly that Greddy turbo kit looked to be about 330-340rwtq at about 450rwhp and 6.4psi.... so just dial back to 4.5 to 5 psi and you theoreticly should have a 400rwhp/310rwtq car. Still would be very very quick at 3200-3300lbs.
