I got the sr20det on my 89 240sx. Does anybody know how I can connect to my sr20 ac compressor??

 

the only guys ive seen with a/c on an sr have converted to r134a.

 

I believe some A/C Compressors bolt up with out any modification but that is a very rare occurance.

Most of the time, hardlines need to be fabricated to connect the A/C system. I remember seeing pix of this at Phase2motortrend.com

 

im pretty sure sr compressor bracket and you use the ka compressor and it bolts right up.

 

Use the Ka compressor. I can't remember it has been forever, but I think only three bolts line-up which is enough.
