I'm thinking I'm going to add a/c to my swap. All the wiring is there, and it's just cluttered up in the corner of the engine bay, I could either get a new harness without any a/c stuff, or put a/c on the car. I'm thinking putting a/c on the car would be more enjoyable. It's not a full out race car, and the sucky thing with having a harness without any a/c wiring is that you can't just add it in whenever you want.

So my question(s) pertain to what parts you suggest using. Obviously the 4th gen a/c compressor is going to be the first thing on the list. I have all the original a/c parts from my car, including the condenser, box, and all the lines and relays. Is it even possible to use all this stuff? I'm assuming many of you used 4th gen lines because they're going to be shaped to route straight to the stock location of the a/c compressor, correct?

I'm trying to get this done as cheaply as possible. If you've got any spare parts from when you may have removed a/c from your car and you could throw my way, it would be greatly appreciated. My wife would love it too, she probably wouldn't mind riding in the car as much as without a/c.

One of the variables that is making me hesitate on doing a/c though, is that I'm afraid that the a/c box and lines will be in the way later down the road when I want to do a turbo. I've got a relative of mine looking for a hair dryer and I'm pretty sure I could sell my exhaust setup rather quickly if I wanted to get the new turbo headers. So it's definitely something I am considering, and if I put a/c on the car, it might have to come back out if I do that...I don't know...

 

i thought that there was a bracket to use all the older a/c stuff.

 

I would think the 4th gen compressor grafted to the 3rd gen receiver/dryer could be done to keep it out of the way of a front mounted turbo.

 

Excuse my ignorance, but is the reciever/dryer the aluminum canister that mounts right in front of the a/c box?

I thought about getting that custom mount, but it's hard to find and expensive. I've already got a tubular k-member so running a 4th gen compressor is a non-issue.

 

Yes. The 4th gen system puts that up by the radiator.

 

Cool beans, maybe it will work out after all. Really the only turbo LSx swap I've seen is that guy with the black '92 Z28 with red heritage stripes and he had some wicked turbo piping that went under the front of the oil pan over to the passenger side, and I thought it might not work that way with a/c. I know his car was a/c delete.

 

I can't really be much help but I'm interested to know the same thing. My car doesn't have the a/c hooked up right now but I would like to reinstall with the lsx.

Mmmm 11 second street car with nice cold a/c haha

 

I got this idea from cam. I used the 4th gen compressor, 3rd gen condensor,evap,and drier/accumalator. when it came to lines i used the 4th gen compressor line its one piece, with a notched stock k-member there was slight bending to get it to work but i looks great. I cut both ends off (the one that went to the drier and the one to the condensor) I got ends from a 97 s-10 and had a local weld shop weld them together. 4th gens use a high side sensor and 3rds use a low someone might correct me on that one maybe. I wired the low side sensor on the drier to the computor using the sensor signal and sensor ground. i sucked it down and it held 30in so no worries there. I have yet to charge it and try it yet but in theory it should work. I will try to get some pictures of this tomorrow at work, i have been doing this swap for a customer. it clutters things up on that side so a turbo might be interesting but until then it should work.

 

AC will NOT work with a turbo set up unless you use one of them cheap ebay kits. On a truck mani build the pass side mani goes right where the compressor mounts, and even with the sw turbo headers i highly doubt it will fit

 

Here is a kit from Hawks that lets you use the 4th gen compressor and everything else form the thirdgen.....

My take is use the 3rd gen evaporator, a 4th gen compressor (I have one for cheap, if you need) a new drier and a modern (hi-flow) condenser. Of course, a pressure switch, too.
Vintage Air has an info article for their hot rodder customers and they stated most any evaporator would work with a new style compressor and condenser. That's good for us as new 3rd gen evaporators can be had and the other stuff is easy to get.
BTW, the F body compressor would not fit on my C5 engine, so I have an extra lying around.

 

Anyone ever get a/c and turbo to co-exist on a lsx third gen?
