The big outstanding question i have is the AC. Heating doesnt appear to be an issue as the radiator will be front mount. now that the engine is in the rear, what about ac components. pain to run tubing from rear to front.
Will have a standalone ecu and harness for the new motor. Electric compressor could be an option, but pricey.
I'd just make custom hoses or tubing and run them right along the same path as the radiator and heater hoses. Looks like plenty of room down the tunnel for everything looking at a previous pic of the donor
