93 Rx7 and Cosmo 2 rotor

Hi,

Surely I am new to the Rx7, I am however a accomplished Drive-ability specialist concentrating on General Motors engine packages. I have a 93 Rx7 and am needing advice as I am going to install a Twin turbo 13b from Japan which was originally in a Cosmo. I don't have the engine as yet but will in a day or so. I would really appreciate some guidance .
