another AC question:)

I have an 82 320is, but it has a m20 stroker engine. 87 bottom end 88 top.
I have the e21 console, with the e21 evaporator.
So can I just get the e30 engine bay parts and it will work, or is this going to
be a major problem putting a e30 compressor/condenser/and hoses in this car?
thanks,
jm

Since you have an m20, poke your head over to mye28 and get the brackets for a sandensen compressor. Cheaper, more efficient, and easier to replace than the e30 unit. I want to say most guys go with the 705(708?) compressor model. Then it's just two custom hoses from the compressor ports outward

thanks for the input. The bracket that fits on the m20 will not work?

It will as far as I know, but it's just older, less reliable and less efficient tech. You'll be able to run r-134a properly as opposed to straining the system. I'd personally replace the condenser up front as well with a parallel flow and make sure the aux fan is working. Toss in a hi/low pressure switch and you'll keep your investment from going boom.

I think the adaptors sold there are just adaptor arms from the m20 bracket to the compressor
