FD3S_wanted

Like I said in another thread I'm rebuilding my 13B-RE. This weekend I opened the engine and discovered that the rear rotor has been eaten by an apex seal. I have a s5 TII rotor. I want to know if I can use the good RE rotor with the s5 TII rotor.

Visually they look the same.



Also, I know there is supposed to be a letter on rotors to specify which can be use together. But where is this letter, there is a ton of letters on the rotor.



Another question about the RE. If I change rotor bearings and stationnary gears bearing, which one should I use ? 13BT or 13B-REW ?



Thanks!

Cheers!

they say you can interchange the rotors on a S5TII with a FD engine's rotor, they sare the same size and weight.



BUT! the FD rotor has their stationary gear hardened from the factory.



They also say that FD-REW engines and RE cosmo engines share the same rotors. So i think if you can somehow replace the stationary gear then yes you can use it?

It's basically the same thing.

i thought the cosmo and s5 t2 were even the same part number? did someone post that?

Thanks I will use the TII rotor.



And for the bearings, which one should I get for the RE: 13BREW or 13BT ?

funny question comming from the guy that always has the p/n for everything.

i dont have the cosmo parts book and mazdausa only has 1, its the early one too

REW has a slightly deeper (and wider?) oil channel in the rotor bearing.

It can be argued that that this is better.

the part thats not better is the part where its sized, because they dont list the original size anywhere! just +/- from the original
