Default Who kept A/C in their WRX swap?

Doing a swap, and I'm looking for ideas on how to keep the a/c.

I see two major problems; the hose hardline that runs across the firewall just above the pitch stop mount and the canister in the area of the turbo/downpipe. Both look like they will interfere with the WRX drivetrain. (this is going into a '99 RS BTW)

Right now, the stock engine is out, but we still have the original compressor connected to the lines in the hope that we wouldn't have to vent the system.

It doesnít interfere, just a tight fit. I was able to keep my original AC intact with a full WRX drivetrain swap. Only thing is youíll probably have to keep all the hardlines and the AC pump as the WRX wiring and line size/mounting is different.

Good to see you didnít vent the system either (unlike me who now has to pay $$$ for a full low/high pressure recharge) but how the heck did you work around the in-cabin AC core/vent/box thing to do the wiring?

Easiest thing to do is go to a local shop that has an A/C service machine and drain the system. At least you can get some form of credit for charging it back up afterwards. Then you can remove the heater/ac box. It makes life/wiring alot easier.

One of the things I have done with the hard line that goes along the firewall is to cut off the mounting ear, where it mounts to on top of the pitch rod goes. Then run the line under the pitch rod(a little bending required). That should give enough clearance for the intercooler.

Canister should not be in the way at all.

Ok, thanks for the good news. I figured we would have to vent, but I thought I'd wait till it was a certainty.

Currently in the process of this swap, and i didn't do a damn thing with the a/c.

It bolted up fine, yes the clearance between the firewall and evaporator is a bitch, but you can get around it..

My car was an oddball and the A/C compressor wouldn't fit with the newer intake manifold. The newer cars swap right over.

I'm in the process of refitting an STi system into my car.
