    you can just convert the fittings and run r134a in the stock system, its not ideal. refill with r12 and leave it alone is ideal, or if you want to run R134a the right way use all the factory r134a AC pieces from a late model e30 with r134a from the factory.

      Whats the most common type of reman a/c compressor for the M20? I cannot find a seiko unit at all so I'm forced to just use a denso unit and change my lines. But which denso unit?


        Here is a link to ebay you will find every reman compressor that was installed as new equipment. There are Bosch/Behr,Nippon Densoand and Seiko Seiki. I got lucky a friend has a Euro. boneyard and he had a '92-'93 vert with a Seiko-Seiki compressor that says R134a the BMW part # is 64 52 8 39
