Anyone know if this tranny will work on the 89' turbo version of this motor?

yes it works

So it's not to weak?

nope, not to weak.

I have been using a non-turbo 1989 5 speed transmission on my 1986 turbo Z car with good results for 5 years. The '88 and '89 transmissions were also used in nissan trucks of those years. So I do not believe they will wear out any time sooner than a turbo transmission. pdfflyer@adelphia.net
