Carburetor question

I have an odd application for a rotary, a 1967 Renault r10, a small care that has little to no power and little to no aftermarket support. Like anyone else I want to make it fast but almost no engine will fit. I figuer a 2 rotor will work with a custom bell housing but I would like to make it carbureted, is that a hard task, if not what is needed.
