Aside from the living hell that would be swapping the engine,I doubt it.It is hard enough to find parts for the si but that little carbed creature really has no friends.You could swap in a si engine and upgrade that but the thing is aside from the mounts you have the same amount of wiring going from the carb to fuel injection anyway.I'm not sure of the specs from the other carb models but maybe you could swap out parts from say the civic 4 doors or something to that affect.
