I am planning to upgrade my 2002 RSVR to 57 mm injector bodies. Problem is that the 57 mm bodies have the black plastic injectors with different connectors from the metal injectors fitted to my 51 mm bodies. Does anybody know whether it is possible to switch the injectors from 51 mm bodies to the 57mm's so that connectors from are will be a direct fit? If so does this have any negative impact on performance?
