AC from newer vehicle swap

I have read that several people have swaped out entire AC systems in their conversions for a smaller lighter, less power robbing 134 swap. My question. if I replace all, drier, condenser, evaporator compressor etc. what other mods do I need to make? Do newer compressors operate /switch on the same voltage? in other words can I use all my interior controls and wire to the compressor just switcing the connector if needed to wire the compressor?

Any tips from someone who has knowledge or has done this would be great

 

that's what i had done to mine...everything inside the car is stock.

So no problems with clutch amps/voltage for the compressor? I would assume the same but that's the kind of thing that always jumps up and bites me.

 

I've looked at classic auto air before but figured I could spend a lot less at the local salvage yard.. Running out of money working on this thing and need it running soon as my son has turned around and is working on it again. So this will be his first car.

 

Voltage is the same. Most Compressors use a diode somewhere between the hot and ground wires on the compressor to limit the AC current that the clutch produces. If you are not using any computer stuff in your car it's not entirely needed. I still recommend it.

 

Little off topic, but something I have been wondering about for a while is can you install all the newer style stuff under the hood and have it look totally stock inside the car? At some point, I'm going to put A/C in my '69.5. I want to get one of the factory package trays with the little round vents, and have that be all that you see of it. I'm not much of a fan of the aftermarket type units that hang down under the dash.

 

Other then adding an AC inclusive heater switch and the box under the dash I don't see why not.

Yea, I saw. I just wasn't sure how you had done yours. I don't want a vent in the center of the dash like the factory A/C cars had. I just want vents on either side of the package tray.

 

If you got all the in-dash A/C (box, vents, etc), I don't see why that wouldn't work. The only problem you might have is mounting the evaporator in the factory location if you're not using a Mav evap. Remember that the problem with most converted systems is the condenser is too small and doesn't dissapate heat well. So if you're yanking parts for a conversion - a 134A system is probably the best bet. This is also a great chance to use a rotary style compressor.

 

Put an evaporator in place of the heater core. To hell with the heater!! It don't get cold in the south.

 

It's gets down into the low 20's/teens for a few months. I need heat.
