Don't forget there is a difference in turbos between the 5-spd and autpmatic Z32s as well. The auto came with a .54 A/R housing and the 5-spd models came with a .63 A/R. So the turbos on the auto would spool sooner but also run out of breath sooner too. The turbos are only running on 1.5L of displacement too, where as on a SR20 it'd be 2.0L. that's a pretty substancial differnce for a turbo. I had thought about it too, as my dad has a 300zxtt, and we upgraded the turbos (well, the dealership did, HAHA) so there were two just sitting there (but they were also pretty much dead too). His new bll bearing turbos spool up SOOOO fast, it's sick! Hope this helps.
Oh yeah, pointless tidbit of info... The automatic 300zxtt can beat the 5-spd to 100mph. Even though it only has 280hp vs. 300 in the 5-spd.
