AC update
I have an 82 911SC and am thinking about updating my AC. I've been told I need a new compressor and AC lines and some other parts.
could someone give me some specifics on what exactly I need and the best place to find them?
Thank you.

Chris,
Are you going to stick with R12 (still available but no longer produced, expensive to recharge) or upgrade your system to accept R134 (currently in widespread industry usage)? I investigated this on my SC, and it was recommended I replace most of the components (compressor, drier), along with installing barrier hoses. At the time, total bill would have been around $1K. If you're going to replace major components anyhow, you may want to consider the upgrade to handle R134. There are several vendors who advertise in Pano and Excellence. Griffiths is one that comes to mind.

It's easy to improve on the early compressors, (<a href="http://www.griffiths.com/porsche/ac/porsac911.htm" target="_blank">Griffiths </a>sells the Sanden model, for example), and the old non-barrier hoses should definitely be replaced (a local hydraulic hose shop is probably the most cost-effective way to do this). Also, consider increasing the condenser area. I added the <a href="http://www.scottsind.com/Permanent/911.htm" target="_blank">Performance Aire</a> under-belly static condenser, and eliminated the rear one. I get 37-degree output in 85-degree ambient with R134a.

You might want to check out Vertex in Miami,they have very competitive pricing on new rotary compressors,you also want to change out the rubber lines with barrier type hose which does not weep,you also want to change the receiver/dryer,if you do all this you will get acceptable AC performance,to get really good performance adding a under belly condensor seems to be the ticket.
