anyone know how much it will cost me to get a/c running after the installation of an rb25det?

I see you have thoroughly researched this....And you obviosly know that the digital climate control takes the signal from the pressure switch and triggers the conpressor on the Skyline setup and the 240SX controls it with the engine ECU....Plus the disscant pellets inside the drier are shot after 24 hours of exposure to the air....
I cant believe that you think you are the first to think of this....
You cant really use the Skyline digital climate control because the Skyline controls the AC/heater boxes under the dash electrically and the S13 uses cables...
So back to the issue....if you can create some kind of setup that takes the signal from the triple pressure switch, interprets it, and triggers the compressor. Where are my electrical engineers!?

Why not use the skyline compresser and the S13 ECU to control everything?
If you can get the wiring done, then I don't see why it wouldn't work.
The only problem I see with that is the inability for the S13 ECU to increase the idle to compensate for the load from the compressor.
I think I asked you(Jon) that about 4 months ago. :rotflmao

goto your local AC specialist.. they can do it for you.. there are seperate control units they can put in to stop the "exploding" compressor.. they put custom AC sysems in all kinds of cars that didnt come with them..

Well if you get the wiring right you really think it would be a problem?JonPowell said:
Yeah but the point is to make it cheap for us, plus it would be something we could do ourselvles.spoolinrb25det said:
Also, will the A/C lines from the S13 bolt onto the RB compressor?(I don't think there is enough clearance anyway, even with the KA in the bay its kinda tight in that spot)

Well the way i look at it, id pay extra money to have a clean setup that is safe and works (custom) than a jerry rigged setup that works but isn't exactly safe or reliable. If i can get a pressure switched installed along with the custom lines and its not "rediculously" expensive i would do that. Guess i need to go to an ac shop and see.

if your looking for cheap.. your way over your head with an Rb swap..

it all comes down to..
1. wait till someone comes up with a DIY method and fry your ass off all summer while you wait.
or
2. find a trust worthy A/C shop, break bread, then snap off some mustangs with the A/C on.

Well if the voltage varies...a few things need to be determined. First we need to know what voltage constitutes the shut off voltage (voltage at which the pressure is too high). Knowing this you could make a simple switch that you could feed into a relay to supply power to the compressor. It would not be anything fancy, but it would turn the compressor off if the pressure was too high. The best part is that it would only require a couple dollars, a trip to radishack, and some knowledge on how to build simple circuits.
