Hi guys and gals, Need to know if a s1 upper plenum will fit on an s2 engine and lower plenum. I found some info but mainly regarding the s2 lower plenum not fitting the s1 heads well.. Cheers, Joel
Yes some grinding required to clear injectors but not tooooo hard. IIRC it's only the injector for number one that had issues with getting the plug on and off unless you grind the lower mount for the throttle cable doflicky.
