The internals for the 240A 964/993 alternator are physically too large to fit in the 911 housing. TBH, our systems work fine with the 175A and the 240A is only recommended if you have an exceptional electrical requirements. It also requires changing to a polyrib belt.

I'll check in with a general update on heat pump system in a couple of days.
Thanks for the reply and I appreciate the work you’ve all put into this effort. I will be in the market for this soon as I am deleting what’s left of the HVAC in my car.
