In the build up to get my car as close to perfect for me I can manage, I'm trying to source a new compressor. RockAuto has complete replacement kits for both the CA18DE Pulsar and the CA20 200SX for the US. Which of these would I use?

The Pulsar one MIGHT work, but I think the pulley is wrong. If you have a stock A/C compressor, maybe you could swap the pulley over. I don't think that picture for the CA20 is accurate, as I'm pretty sure they used a V-Belt for the accessories.

Yeah, that's the rub. I've got two compressors, both with obvious damage from being stored outside (my ex is a..well...anyway), one of which MIGHT be a CA compressor, I just don't know. I'll get some pics tomorrow evening and post them to see if anyone has a clue which might work (pulley anyway, I can always get the KA24E compressor, as I'm going to have new lines made up.)
