I have tried searching but having no luck. I am trying to find out which years of 300zx and 350z's had the factory turbo option?

Turbo was available on all years of 300ZX's (84-88 for the Z31 body style and 89-96 for Z32 body style, 89 was a gap year for the 300ZX in some markets I believe).

Don't believe there is such a beast as a factory 350Z turbo. Only things I've seen have been aftermarket mod's and for whatever reason, I've seen 350Z's sporting aftermarket superchargers much more often than turbos.

Cheers,

Thankyou so much for the info.
