I have been planning to buy a JDM 2-rotor from Nippon Motors, since their motors are only a little more expensive than a JDM turbo. I just called Nippon, and they said that all they have right now is the Cosmo two-rotor. Does anyone know if the Cosmo turbo will bolt on to an American FD motor? I've searched the forums, and a few people have mentioned it, but there's never a follow up.
