Which would be more bang for the buck to replace? The evaporator or the condensors? I have already replace the compressor with a Sanden unit, added a Pro Cooler and rebuilt the hoses with barrier hose. Now looking to go the next step.

Thanks,

Have you considered ADDING a condenser/fan assembly in the front left fender? That will give you the most improvement, and bang for the buck!

One of the big deficiencies in Porsche AC systems is lack of condenser capacity. So anything that improves condensor efficiency will help. You've already added a procooler, either adding another condensor or upgrading an existing one will help as well.

I would think the condenser would make more of a difference than the evaporator. It's also a little less work to remove/replace one of the condensers than the evaporator.

I used a griffiths additional condenser with a fan. It's mounted inside the back left fender
but, I also changed out the evaporator, hoses and compressor. Works gar better than any stock system for a 1973 model 911.

Biggest bang...fan for the condenser! Do this before you get another condenser. Do a search.
