You can do it, but you'll need both the 86-88 front and rear counterweights. You'll have to be careful with the tuning.

I wouldn't do it without a standalone ECU.

well at least it has been tried. does anyone know of a link to some info about trying it. or at least info on putting different rotors in different housings.
about the tuning i have heard of a very reputable shop around hear somewhere. i guess i'll have to go and find it.

N/A has 9.0:1 compression vs. 8.5:1 for the Turbo.
Doesn't the Turbo have larger 3mm Apex Seals vs. 2mm (Not sure about that).
I'd stick a J&S Knock Sensor on there as a SAFETY MEASURE.

All 86+ rotaries have 2 mm seals. The 86-88 NA motors are 9.4:1. 89-91 TII rotors are 9:1.
You sure about that? I read that the 89+ are 9.4:1 and the 86-88 are 9:1 which is part of the reason for their increase in power. The 89+ also has slightly lighter rotors and the intake has been changed.
