What specific parts are different between the 20B and 13B?
I know the e-shaft but what else ( eg. tension bolts, intermediate housings)?

Are all of the parts specific to a 20B available new from Mazdatrix or some other supplier?

I'm no expert but I know the tension bolts and intermediate housings are different.
There may be some others. Bruce Turrentine has built several three rotors out
of two rotor parts. Tracy may know as his three rotor was built that
way by Bruce. Bruce does not respond to my email for some strange reason.
If you have a connection with Mazda factory racing one can buy three rotor parts.
