Been awhile since Ive put one of these together. I need to replace both rotor bearings as I believe they are mushroomed. Both rotors were slightly rubbing the plates. Im replacing the eshaft as well. So my questions are:

1. Which bearings do I use for the rotors, the s4 or the FD?

2. Stat gear bearings both look great, do I reuse or not risk them being mushroomed as well and replace?

The eshaft is FD, rotors are s4 turbo.

Any reason you want to use those? Or do you just have them laying around. The lower compression will make less low end torque.

high boost motor. I made 475hp / 425tq @ 19psi with them last year. Not really worried about it.

I would use these bearings at that power level 74-92 Rx7 Race Rotor Bearing (4801-11-111)

Switched out the turbo to a borg warner s400sx4-75... thatll be less than low boost on the new one

Still, the 93+ bearings have a deeper oil groove so I would go with the race bearings. You might also want to side clearance the rotors or at least find out why the rotors contacted the irons.
