The 87/88 TII cars had lower compression rotors, thicker side seals
The 89-92 TII cars had lighter, higher compression rotors, thinner side seals

Does that mean the 87/88 since it runs LOWER COMPRESSION & has thicker side seals can handle more BOOST?

 

Really there is no such thing as "handling boost"
How much boost you can run is determined by a number of things, the main ones being the fuel octane you are using, the intake air temps you are getting and how much fuel available for delivery you have.

Detonation, caused by leanout is what kills apex seals, and depsite what a lot of so called experts will try to tell you, as long as you keep the A/F ratio in check rotary's are pretty much industructable in the factory spec as long as you dont go for over 600rwhp.

 

And re-inforce the frame & engine mounts so the engine doesnt' start spinning externally

 

HAH, that would kick ***!!!!! Well, as long as it wasn't MY engine.
