| As I mentioned mine are twin injector throttle bodies that came with the engine courtesy of Steve Caffyn owner of CSC Racing.
I asked John Hackett about fitting the 54mm shower injectors off my 748RS (also found on a 748R I believe) but he suggested I would be better off sticking with the twin injector setup, maybe because he had already set the the whole package up and done a chip for it |
