Is your AC system all stock from the 4Runner or is it from the 3.4 donor? Are any of the components, like the compressor and/or condenser new? Interested to see how well it cools for you with that 100+ deg temps. I live in S. FL and my AC (converted to r134 by me) is not very good. Works ok in the morning as long as I'm moving down the highway. In the afternoon when it's 90 deg and super humid it really doesn't matter if I'm moving or not, it's just not great. I'm thinking of tearing it all down and rebuilding the compressor, getting new expansion valve and drier, and just flushing everything really well, but I'd love to know how yours performs.
