Just wanted to know if anyone has had experience retrofitting an AC system back into an Rx7 that didn't come with one. I have the S model 85 Fb and often times complete AC systems come available on eBay from wrecked Fbs.

We all have to do our bit in light of global warming.

 

All of the 81-85 models are prewired for all accessories. Round up al the parts and install. The holes are already in the firewall for the evaporator core tubes to connect to the A/C hoses.
You need the following.
1). A/C compressor with clutch. Make sure has the adjusters on it to tighten the compressor
2). A/C condenser
3). Receiver drier (Buy new)
4). Evaporator core box with core and expansion valve
5). Duct between evap box and blower
6). A/C hoses
7). A/C mounting bracket and nuts and bolts to attach compressor to Engine
8). A/C belt
9). Freon
10)All new O'rings.
