Will the SR swap cause losing the A/C ?
if yes…is there any way that can get a A/C for SR??
i’ve got the A/C compressor for the SR in my garage if yours dosen’t come with one!
You can do one of two things get your stock KA pump and make a bracket to mount on the SR.
Or you can take the SR pump and get new lines and refill it. (Costly)
I say forget it alltogether.
since the S14, the ECU controls A/C i dont think anyone has been able to figure out how to get the A/C to work with S14 models. S13 models do work, however.
so swaping a S14 will b no A/C …? oh crap… 
a/c is a useless waste of gas, horsepower, and weight
we live in canada, roll your windows down… its not that bad.
Only time i Use is A/C is with girls or to defrost my windows, it would suck not having it, but it wont suck having an sr lol…
that was one of my concern 2… for girl…and in the summer time… if the window get foggy… u need A/C …~~ well…~~ if there is a A/C it is a bonus …
uhm for the foggy windows why not just keep a towel in the car? the reason why i think ac is cool for when you have girls in the car is if they are part of the palazzo/plastique herd (my normal hunting ground) their makeup starts to melt in the summer heat and then that super hot chick you picked up last weekend looks like a swamp monster, thats about the only reason why i would bother with a/c. 
AMEN!
If you really want A/C you can have it. Worst case scenario you might have to run an aftermarket a/c system.
