My 260Z, with what I think is a stock rear end and 4spd, runs about 3900 at 70 mph. The stock 260 rear end is 3.364:1, the lowest of any Z made. For you to be going 90 at 4000 RPM, you would have to have even a LOWER!! rear end than that. Maybe it is a non-z rear end? By the way, your accelleration off the line must suck, does it?

pretty much ....maybe 0 - 60 in 9 seconds....i haven't tried timing it accurately but that's about what it is...it's till goods enough to beat a lot of otehr cars though.
