The a/c in my 73 2.0 does not work. It needs several things including a compressor. Are there more efficient new ones out there that are bolt on or have new mounts? I plan to convert to R134. I was thinking of taking the old lines and getting new ones made locally.
I know most of you will say you don't need a/c, take the top off. But my better half who helped me buy the car likes a/c so that is not an option. So any advise and suggestions would be greatly appreciated.
There is a kit out there that converts the system to R134A using a Sandon SD508 compressor. I forgot who sell the kit but if you do a search of 914 A/C kits you will
find it.
This is the site you have to call them for a 914

Hope this helps you.

Hey I got a new compressor for sale, just P.M. me...
I thought about putting A/C in my 73 restoration, but changed my mind at the last minute...I had already purchased the compressor...
2-OH!
There is an outfit in San Antonio I believe that does A/C for AC VW cars, should be able to hook you up.
Betty's car has a DPD system that was converted to R134a. It was easy. I bought the compressor kit from http://www.iceac.com. It is literally a bolt on setup. I then took the hoses off and had them remade with barrier hose at a local AC shop. Bought a new dryer and o-rings, and hooked it all up. This was 5 years ago. I had to do a top off of the refrigerant for the first time this spring. It will cool you down with no problem on a 100 degree Texas day.
Good luck on the AC. It makes a 914 a true daily driver.
Just a few comments as I have redone the AC in my 911 and I will be adding AC to my 914. First off the Sanden 507 or 508 are excellent compressors but are not rotary they are wobble plate piston type. They are very quiet,small,efficient and use very little horsepower. You do want to replace the old porous rubber lines with new barrier hose. If you can find a local shop to work with you all the better that's what I did. I used the old fittings and had new hose crimped on just make sure for any angled fittings you have the clocking position correct. The normal downfall for Porsche AC is not enough condensor space and poor effiencecy evaporators. The two condensor setup from what I can tell works very well but I wouldn't rule out a 964/993 OEM setup from the 1990-1998 Porsches. This condensor is efficient and has a powerful fan and I think it will fit in the rear wheelwell of a 914. Also in place of the standard receiver/drier there is a product called a Procooler which will help with additional cooling. I don't know what's available for a evaporator, I know Rennaire and others offer a upgrade for 911's but I have to learn about 914's. And last I like useing HC12 for refrigerant instead of R134A. HC12 is flammable but it cools better than R134A and runs at lower pressures. This is mostly for the DIYer as most shops don't want the liability of flammable refrigerants. Good luck with your AC project.
Barrier lines and R12...
It's doable. I've seen 914s with a huge dual-pass condensor under the car (not in the front trunk). Just got to be careful with speed bumps! That car blew 50ยบ out of the vents...
