I already am aware that the TII rotors carry a slightly lower compression than NA rotors do. That is actually why I ask the question.

I am going to supercharge my NA this winter with a full rebuild and a streetport.

I am also debating on a small wet shot of NO2.

The lower compression will be easier on the entire system when I am really getting on it, so I am curious if the TurboII rotors will work in an NA. Of course, using the matching e-shaft and counterweights, but using the NA housings and intake system.

 

I believe so... anyone know for sure???

 

you are going to supercharge and get nos?

 

yes they will work, not sure if you haev to use turbo counter weights or not btu if you do youll either need a turbo flywheel + tranny becuase counter weight is in flywheel.

 

counterweights will be the same as long as its the same series RX-7.

 

I figured that I would need the TII flywheel and I was looking at getting a TII tranny anyways b/c my NA tranny has 191k miles on it and 2nd gear synchros are starting to crunch when I really get on it. Give it a half second before shifting into gear and it is fine.

I will make sure to find some S4 parts then. I thought they would fit, but wanted to confirm my thoughts with some others.

As for the supercharge and NO2.....it is a thought. The supercharger is a definite "go" this coming winter along with an entire tear down and rebuild with porting. I have a huge list to do.

I am going to try and use the existing intake system minus the black plastic flex pipe from MAF to throttle body. I am going to try and fabricate the piping to go from the MAF to supercharger to throttle body without removing the stock airbox and intake neck. Make it look as much like factory installations as possible on all my mods.
