So I know this probably been asked befor but I want to get a complet list of what I'll need and some questions I'm confused about with interchangeability of parts.

I plan to start getting parts to build a 12a based 4 rotor motor. I know there's a huge cost involed and I plan to buy parts here and there and the buddy I own a car with is pitching in.

I know I need I have a running 12a in my 1980 rx7 with great compression. I know I'll have to buy at least one more good motor and a 3rd middle plate plus two stationary gears to be moded
