If this car weren't a bargain basement swap, i.e. basic 350, I'd pick it up and turbocharge the damn thing. Throw a serious rear end in the back, some aftermarket heads, forged internals, big clutch and a sturdy manual box behind it. Rotaries are not my cup of tea...prefer a reciprocating assembly and a nice, aluminum small block would make that car interesting as Hell. I'd throw a Scoob motor in there, but the STi hardware is way expensive and fitting an H4 in that engine bay would not be fun. Would be a fun project though.
