So I’m trying to dig up info on the new ac/heat system. I have a 73 911E LHD. With the RS plastic tank.
I’ve read the CR forum instruction and have a rough idea of the layout, components and needed changes.
So far:
- new alternator. And new wiring in a couple places. Engine is current out and I just finished some harness upgrades so now is the time for that.
- cut off drivers side batt box and cap, OR create attachment structure/fastening points and shields in drivers quarter for fan and hoses and heat excngr.
- figure out interior ducting and outlets. Dash is non AC. Acckk.

I’m currently planning on new carpets and doorcards and while I’m there it’s time to redo the audio. The existing set up has Alpine and Nakamichi amps in the smugglers box. The Nak amp stays, a classic a/d/s amp will replace 2 Alpines.


With the CR compressor going in the smugglers box all the audio gear needs a new home.

So… the big question is: what changes in terms of physical space needed will the addition of heat require? I assume that in a heat pump system such as this, that making heat is essentially reversing the normal flow of the core components so I’d anticipate changes to the components but no large item additions? Perhaps a reversing valve but there’s space in the smugglers box it seems.

Does anyone have any intel?

Other considerations: what have people done with the interior controls? It would be cool if it looks vintage.
Also. My dash is pretty new. In good condition. How to handle AC venting?I have decent fab skills.
