actually i think there is 2 defferent set because if you go to mazda they will give 2 rebuild set option turbo and n/a
Rebuild kits are different from n/a to t2 based on the gasket set.
I have an s4 n/a gasket set for my 91' t2 motor. The only difference is you don't get the metal turbo gasket and ofcourse wrong engine to lim gasket and lim/uim gsaket.
So you have a hyrbid to4B. That would make sense. I use to have one also. to4b housing/60-1 wheel bolted to an s5 t2 turbine housing bored to accept a bigger exhaust wheel. But you said .96 turbine a/r?? How does that make sense if you are using the stock turbine housing?
Sorry I didn't mean to come off as a ********

oh yeah what i meant is that when i bought the the turbo it originally came with the 96 a/r with the housing , then i took the t2 turbine housing to get bored to accept a bigger exhaust wheel ....but yeah it has the bigger blade

I could swear there were different materials for the two, but I could easily be wrong.
As long as you have the fuel and correct ecu for timing and such, it should work in theory. I imagine you have to keep the boost lower to blanance out the higher comp rotors though.

Where did you get that idea? Higher compression actually raises the VE, which in turn increases the amount of air/fuel entering the chamber at any given time. Boost is entirely relative to how much air the engine is flowing. But thats still beside the point, because boost and compression ratio are completely independent of each other.
Aurosting, how about a complete run-down of your setup?

So why did you switch to a t2 motor? And why were you using a t3 turbine footprint before?
Reason why I went to a turboII motor was because after a year boosting the n/a motor I did blow it up. Installed a T4 T70 .96a/r p-trim wheel clipped 11deg. The n/a motor could not move the volume of air/fuel this turbo could move. I tried anyway. Well at 25psi of boost my sds hit fuel cut, so at 25spi the motor was treing to run of only 2 550cc sub injectors.
Found another motor and it happened to be a turboII motor. rebuilt it and bought a new T66 .96 p-trim.

before you go buying bigger injectors find out your injector pulse width/duty cycle at your desired boost level at 7000rpm. This will let you know if you need bigger injectors or maybe you can get by with increasing you base fuel pressure a few psi to compensate.
Just a thought.
