Just wandering if FD rotors would work in an FC, and why or why not?? What are the pros/cons of using FD rotors in a FC block if they do work?

Thanks,

Theyre the same as s5 turbo rotors, 9.0:1 compression, 9.5lb. They're good for a turbo/boosted application, useless for nonturbo.

 

Ah, I knew that too... just got caught up thinking about all the complicated stuff, and not looking at the simple stuff. Thanks,

they are same as S5 TII rotors, but i think they have better stationary gears and 3 window bearing already?

 

Yes, they work. Same rotors as turbo Ser 5 rotors.

They are the same weight as the Kouki turbo rotors, but the rotor face and "tub" is machined; only the Kouki tub is machnined, I think. This just makes for better quality control.

If you're going to use them in a non-Kouki engine, you need the counterweights/flywheels for them.

The 3-window rear stat gear being is actually stock for the Mazda Cosmo engines. The FD uses a better 9-hole rear stat gear bearing.
