it might be 1mpg and 2hp, but the whole system line, evap, compressor and all must weight as much as I do... plus up here in Canada, I must turn it on on the mazda at least onces a month for the seals not to dry up... if I didn't have to do that, I'd flick the switch on maybe a week a year.... and it would be exactly time now... it's 35 celcius now and feels like 46 with the humidity in the air... (that's 95 and 115 for you guys that still use the Fahrenheit scale :P)  but like maxpow said, sweating is good for you!

With that said, on my rolla, the engine drives only the essentials... an alternator and a water pump... everything else is for pussies :P

Unless you weigh as much as a 6 year old boy, It doesn't weigh as much as you. On an S13, the compressor is the heaviest part in at 20lbs. There is absolutely zero way it all weighs more than 45 lbs. It's pretty negligible, at best, for a DD. As for my E30, It's ALL less than 1% of the total weight of my vehicle. I lost more weight in my E30 stripping out the trunk tar, AND then adding my Sub.

Yes. I installed my system. Lost a little weight. And maintained my weight distribution.

So I guess that means nobody has done it.  Guess I'll be the first pussy to try it.  I love it when I get an ass load of replies that don't even answer the f'ing question.  Thank you to all that get why a/c is important in different climates.  Besides, there's no way I'm letting my 2 year old sweat to death in a 100 degree car.   Again, if this was a track only car I wouldn't even be posting this shit.

I'm sure it's the same process as an s13 or s14. You'll need the stock s12 ac line and stock sr ac line on the driverside. An ac shop or welding specialty shop will have to cut off the two lines and weld the two lines together. Some bending of the hoses may be needed depending on your turbo setup.

I'll go through this same process once my s13 is tuned, I know ac isn't possible if I do plan to go top mount in the case that I don't like the power band of my current setup. Ac will be installed and working before next summer comes around if I decide to stick with my HKS GTRS turbo setup.

1 day timeout. He wasn't addressing anyone, or all of us in particular. His post was very thought out and nice, and not attacking in any way.
Your was attacking him, DIRECTLY.

Guys, any update on this? I'm done with my SR swap and I plan to make the AC work. I just need help on the wiring, to enable the idle up when the AC is on. Where in SR wiring harness to I need to tap the AC signal? I checked the SR wiring harness diagram and I see 1 AC signal wire and 1 AC relay wire. What could these be for? Thanks guys for the help. My car is nearing its completion.

I am an hvac tech for those with ac systems with the original r12 set up consider looking into refrigerant hc12a (google it) I mixes with r12 and doesn’t require any modifications to system nor oil or expansion valve change its legal to buy with no certification works very well cheaper look it up!  Long live the s12!!!

What is the legal status of hydrocarbon refrigerants such as HC-12a® and DURACOOL®?

It has been illegal since July 13, 1995 to replace CFC-12 with the HC-12a® formulation that was submitted for SNAP review in any refrigeration or A/C application other than industrial process refrigeration. The same prohibition for OZ-12® took effect on April 18, 1994. Because DURACOOL 12a® has the same chemical composition as the HC-12a® formulation that was submitted for SNAP review (i.e., Hydrocarbon Blend B ), DURACOOL 12a® is also subject to the same restrictions.
HC-12a®, as reformulated to meet DOT requirements, is not the same as Hydrocarbon Blend B and has not been submitted for SNAP review. OZ Technology is therefore prohibited from marketing this blend as a substitute for any ozone-depleting substance. [ like CFC-12 ] In addition, any use of this blend as a substitute for CFC-12 or any other ozone-depleting chemical, in industrial process refrigeration or any other refrigeration or A/C end use, is prohibited under the Clean Air Act.

Since HC-12a®, as submitted for SNAP review, is chemically different from HC-12a®, as reformulated to meet DOT requirements, and since it has a different legal status under the Clean Air Act, users of any substance marketed as HC-12a® should be aware of which HC-12a® they have purchased.

Note that the Clean Air Act does not regulate the use of any of these hydrocarbon refrigerants when they are used as replacements for non-ozone-depleting chemicals such as HFC-134a. However, many states prohibit using flammable refrigerants in motor vehicles, regardless of which original refrigerant was used in the vehicle.

May hydrocarbon refrigerants be used to replace CFC-12, commonly referred to as "Freon® ," in cars?

No. It is illegal to use hydrocarbon refrigerants like HC-12a® and DURACOOL 12a® as substitutes for CFC-12 in automobile or truck air conditioning under any circumstances.

Agreed it is not legal for anything other than stationary equipment.  But I use it.  Lobbyiest for r 134 a tried to describe it being dangerous due to flammability.  I say bs people forget they have tank of gas.  The epa is not checking cars for this excellent substitute.  I have put it in many cars with great success.  The refrigerant hc12a was shot down due to DuPont not wanting competition for 134a. Or for that matter r22 substitutes fuck dupont!!
