Here you go mate!
RSi inlet & rocker cover running MFI.
Use the RST injector rail bit between the inlet and the head as theres the thermo sensor you will need. Also need a new fuel line to the cold start valve as thats in a different place and the XR one wont fit.
Throttle body just bolted on with no problems but you will need to change where the throttle cable clips onto from the XR throttle body to the RS one as they pull in the opposite direction.
Theres probably a few other bits but its straight forward when you look at it!
