I haven't played with the CW R4 enough to know if the shaft is different, but I expect it to interchange with the original assembly. You'll never know until you pull them off and try to interchange them.

Randy, I can't recall if someone is making a kit so you can mount a Sanden or not. I know that someone was supplying brackets and the like to replace the A6 compressors, but due to the tolerances for fitment in place of an R4, I think it would be a stretch since the compressor location(s) normally won't allow for a compressor with longer body. The locations I've seen, the body of a larger compressor would interfere with the intake, and or valve covers.

However, anything can be done.

As far as a vendor that has a decent unit, we've blocked purchasing from all but two vendors, Global Parts Dist. and Ranshu.

Tim, I'd say that might be his best bet if replacing the clutch assembly is out of the picture, but there is one problem. A R4 needs to be firmly attached or things will break, I'd use plate steel to acquire the additional space needed to make it line up. R4's can rattle like hell and break mounts, thru bolts, hose assemblies, etc... Seen it many times.

Glen, you most likely don't need a new compressor for the 911 as the 10P15E rarely fails internally, but rather the shaft seal goes. I just sealed and sent one off last week to someone on the 944 board. I'd hold on to the OE compressor at all costs, new Denso stuff is junk now.
