That I do not know. I'd suspect if so you'd need custom hoses at a minimum. By the time you're in that far, you'd be better off to build a parallel flow setup to compensate for the weaker performance of the Gen I A/C setup (and it goes without saying, convert to a Sanden compressor to get rid of the unpolished poo that the R4 is). The Gen II's have a vastly improved system all around.
