Make, more about the engine and transmission combination. Better pictures of the car, dash, interior, etc. Also, since it is not titled, you did get a MCO (Manufacturers Certificate of Origin) right? That will have the manufacturers name on it.
As for the picture, with the exposed rollbar, I do not believe it is a FFR. Perhaps a Classic Roadster? Tough to tell just based on one generic side shot.
