I've found bits and pieces of info regarding swapping rotors in different motors, but would like a comprehensive list of which rotors work in what motors, weights/counterweights, and compression ratios. I guess stationary gear info would be important too. Anyone out there done the research?

Just FYI, what I'm most interested in is finding out if/how I can make the FD rotors work in my six-port out of a GSL-SE and what counterweights I could use..or what lower compression rotors would work with that motor. I figured since I hadn't run across a comprehensive list in my searches, that I'd go for the whole thing and maybe make a good sticky thread.

Mazdatrix has a page with compression ratios and weights.

I was hunting around on their site just yesterday...not sure how I missed that!

So am I to assume then that rotors are interchangeable between any 13B, so long as you have the right counterwieghts and stationary gears?

i've seen debates on this issue. however, i think the accepted practice is to use newer rotors with older rotor housings, but not older rotors in newer housings. did that make sense?

Best to match rotors with the right rotor housings , as high compression rotors have the plugs spaced closer on housings.
