I'm putting an ej22 in an '84 GL wagon and I'd like to keep the AC. I've read through the pdf that Numbchux made but was wondering if anyone has done this recently and has any advice/ideas about any aspects of the operation. Thanks.

I have not heard of anyone doing it. or even trying. but it has been discussed....and I don't think it would be terribly difficult.

 

 

 

mounting an EA compressor to an EJ engine would be quite difficult. between bracket fabricating, and pulley issues, etc.

 

so you'll want to run an EJ compressor. as far as anyone has found here (keeping in mind, I don't think anyone has actually tried), EA lines won't mount to the EJ compressor.

 

you may be able to grab the engine bay lines from the EJ donor, and plug them into the EA expander, drier, etc.

 

worst case scenario, custom lines of some sort.

 

wiring won't be difficult. just a couple wires to the ECU controlling the compressor relay.

 

then a recharge.

I don't know on an EA 81 vehicle but I just did a EJ EA82 swap and have my ac online (the car first moved itself today and is leaving tomorrow for a 1000 mile trip) I got lucky, with the EA82 body the condenser and radiator from the legacy fit real easy, the EJ radiator hoses just needed shortened and the discharge line from the A/C compressor to the condenser works and is just bent a bit more than the way it was born. For the suction hose I spliced the rubber parts (EA from the evaporator which was smaller to the EJ section from the compressor that was an 1/8 in larger. I also spliced the liquid line from the condenser to the receiver / dryer which was the same size. I've got two 10 inch pusher fans in front of the condenser (which couldn't happen with the car's original condenser due to the discharge and liquid lines being in front of the coil) and I'm pretty sure I have sufficient airflow. Something similar should be able to be done on an EA81 (aftermarket condenser? Red Dot etc) When I get back near my EA81 cars I will measure things and see if I can be more specific. Which White Pass are you located at?

kingbobdole kept the AC on his EZ30 Cheese wedge.

i did a EJ to EJ turbo swap, and kept the A/C. the only differance is about 4 wires that have to be connected...

 

tge bigest problem will be getting the compressor to connect to the engine...

I figured I'd have to do some custom hose work for sure.

 

Capn_r: I'm at White Pass Ski Area in WA. I'm thinking that the ea81 and 82 should be pretty similar ac swaps other than the engine compartment shape/size factor. Could you give me a condensed list of what parts you used from each car?

 

Chux: On the ea81....from what you said and from your pdf, I'm gathering that the best route for condenser mounting is gonna be to do away with my hood latch and open that space up for the condenser/fans?

I thought that might be where you were located (I'm pretty sure there is a White Pass in AK also) anyway, I'm about 50 miles west of you. I will be home tomorrow and will do some measuring to see EA81 / EA82 differences. I have the EJ compressor, discharge line, condenser and about 1/3 of the liquid line (from the condenser to the dryer) and about 1/2 the suction line. (compressor end) The rest of the liquid line (from the dryer to the expansion valve on the evaporator) and about 1/2 of the suction line (evaporator end)are from the EA. With the legacy condensor the two aftermarket pusher fans clear everything and work fine. I just got back from a trip to north western Montana and am real happy with the car and the functionality of the AC. I was comfortable in plenty of upper 90s (f)temps and the old car averaged 30 mpg with zero issues. Didn't make me mad at all.

what kinda of swap is that? ej to ej hmmm, did that even affect the AC

keep the ac lines from the 84 and lines from the donor.. at work we have ac line compression fittings that you can connect the lines with.. ill take a picture of one tomorrow at work and post it for you.. only problem i see is if the lines from each car are different diameters..
