    The $500 compressor are typically rebuilt OE units which are still r12 units. I don't see the point when you can get one designed for r134 for a fraction of the price..assuming you can mount it. FYI virtually ALL e30 compressors came with seals that were r134 compatible. I have a service bulletin somewhere spelling them out and it's probably posted earlier in this thread. Point being the seals are not the main issue but rather the pressure rating. Beyond that you need a new expansion valve and should upgrade the hoses since they will leak more and more over time.

    I'd jump the resistor and everything else is optional

      Regarding the LC Wylie bracket conversion, don't forget that you also have to modify the lines to/from the compressor.

      I had Discount Auto AC in Daytona, FL, rebuild the compressor from my Touring. Great result. Great customer service. The cost was about $250, so if you have a rebuildable core and don't want the hassle of upgrading to a modern compressor, that's much cheaper than the options others have posted.

        Quick little update: I checked again and asked ECS Tuning what was up with the two condensers - also noticed that one of them went from ~$100 to ~$175! Sounds like Nissens may have updated/superceded a design with a new one, or something weird like that. I wouldn't be surprised if one of them gets listed as discontinued in the near future and it's back to just a single Nissens parallel flow option for the e30.

        Anyways, bought the condenser and associated mounting hardware. Also ordered the LC Wylie bracket. Next step for me will be figuring out how to fit an IC and aux fan somewhere in there.

          Re: the LC Wylie conversion..... went a different route... made a tie-in piece for the suction side and the factory hose fits without modification on the discharge.

          The A/C belt from the M30 engine'd 5 series fits this conversion perfectly.

          Seeing 53 degree temps at the vents while doing highway speeds.

            Great info and nice hack on the suction hose! So much cleaner installation without oil cooler lines in the way. I'm still addressing that on my '92 cabrio conversion and will post a final summary when everything's put back together and pumping cold air.
