If that $650 includes labor, hell yeah it's a good deal. You need the entire interior portions, including the control box, the actual cooling unit, door control, any wiring and ducting- some of which may be there. The HA section of the FSM lists the components.

Then you need the entire hose/pipe assys in the engine bay, AC relay, condensor, fan, receiver/dryer, compressor, and a special mount for the USDM compressor to mount to the SR block.

Then you have to modify the SR wiring and adapt to the 240SX wiring, (ECU) and man, that is a big job. I doubt the local AC shop down the road would be able to complete this job unless they specialize in SR/240 cars.

Yeah, 650 would be a good deal in my opinion if you are starting from zero.

You mentioned ecu, will I have any issues because I'm running a PowerFC?

No idea. The SR ECU provides a ground signal to just about everything in the engine compartment that has to do with AC. (Pin 106 iirc)

If I were contemplating a job as big as the one you are looking at, I would consider running a toggle switch to provide that ground for the AC relay instead of using the OEM setup. Then I'd consider an aftermarket underdash unit from one of the "classic car" parts suppliers.

The first thing you need to do is check out the 240SX FSM, and the well-published SR ECU pinouts. Using the SR computer allows the high idle to kick in as well.

Respectfully, if I lived in NY, I wouldn't even consider this, unless the original chassis came with the system, or I had total and complete access to a car with all of the AC parts in it. "Then" you'd only have about a week of swapping and wiring to do.

Recommend you run this by Cody Ace on here, as he has some very good knowledge of these systems and sells compressor adapters.

Hey, i sent a email to codyace and posted a thread on nico about trying to do a setup similar to your setup, could you post pics of how much you cut off the lines so they would bolt onto the compressor? You are the only one so far i have found that has any good info on sohc to dohc. I also have a wiring specialties harness so my evaporator/ dryer dp switch plugs in to the harness, so the only thing i need to do is get those two plugs you put part numbers for from dorman and everything should hook up and run right? i know i have my plug for my fan on the condenser that wont plug up but i have dual electric fans and a thermostatic switch that cuts those on, and it has a wire for the ac so that it will cut on when i turn on the AC. Which wire would i tap that into? Heres a link to my thread and if you could email me too i thank you a bunch, getting hot as hell and would really like ac.
Sorry to thread jack.

other then that little can, it doesn't matter where you cut them. Just make sure they fit the compressoryou are using. and the other end matches up with the firewall

thats not what i mean by cutting it, he said that he cut the actual end so that it had just one bolt hole, bc the sohc lines have to bolt holes, thats what im trying to figure out, is all that around the hole just aluminum to bolt down or does it open up inbetween those two bolt holes? or is that cut already? the hose i have to get from the firewall to the compressor wont have that little can on it.

SSonic92

And for the plug that is on the compressor, i can just cut that connector off, and the one on the plug for the sohc line and just get blade connectors right? Reason im talking like this is bc i dont have the line yet coming off the firewall and the compressor yet. picturing everything in my head.

Hi guys, I have a question regarding my AC system. I have a sr20det redtop and I bought my car with the AC lines not yet connected. I managed to have a local AC shop connect the lines and make the AC system work. It works fine now. They wired it without any connection to my ecu.

So now here's what's bugging me, running the car while AC is on when I hit the brakes my rpm drops to 500-600 for 1-2 seconds almost close to stalling but never does. In neutral, my rpm is at 850-900(warm engine) and when I turn the AC on it drops to 600 for 1-2 seconds the goes back to 850-900. With the AC off my car runs fine without the rpm drop when I hit the brakes.

What seems to be the problem? Is it the IACV? I've read that there's supposed to be a wire connection from my AC system to the IACV for idle up is that right? Coz mine doesn't have any. Or is there anything else I should check? Thanks in advance!
