About 6 hours.
It depends on the year. The 1990-99 NA has 222HP, the TT has 280HP on an automatic while the manuel gets 300HP. The previous years are a lot weaker. The 300ZX Turbo made before 1990 has less horsepower than a Naturally Aspirated 300ZX 1990+
the only thing different would the internals of the trans the turbo trans is a heavy duty trans.
