Having my Gs turbo'd at the minute in fact nearly finished, couple of people have ? on having Rs's fitted now i'm told the fella building it is bang on with his builds and knows his stuff?? engine is 1216
The only issue you may find is the slides hanging up if you try to close the throttle with high boost on. Mikuni's do rattle a bit due to the fit and can stick with pressure on the slide - Keihin FCR's have rollers so are a lot smoother and less likely to suffer from 'sticksion'
