Removing AC heat exchanger
For now, I just want to remove the heat exchanger. I need more cooling so it has to go. Until I see that it is successful I don't want to pull the whole system. Can I just pull the radiator out and get to the AC heat exchanger and disconnect it easily? (I have a friend that will siphon off the Freon)
Thanks!!
Thanks!!

Removal of the entire AC system, allofit, was less than an hour for my car. This was with Curly's help, though He's fast. He enters some sort of savant trance when you give him a wrench, a task, and a bottomless beer. Condenser, lines, compressor, and the ventilation box was replaced with the Mazda non-ac connector piece. We did not remove the radiator but the bumper was off. Absolutely take the bumper off.

Second that on the ease/speed of removing the entire A/C. Saves quite a bit of weight - 33 lbs as I recall on an NA.
Job was made easier by having OEM A/C installation instructions which I found online for a 90 NA - http://webpages.charter.net/a7037196/miata/90ACINST.pdf - (hopefully there are some for NBs). Do the instructions backwards.
Anyone with an NA should also Google "A/C delete bolt" - a bolt you have to buy to plug a hole in the block that would weep oil otherwise. Also on an NA, no need to remove the bumper.

Yes, all '90-'05 Miatas with AC have a longer bolt going through the compressor bracket, through the oil pump, and into the block. Removing the compressor bracket requires either a ~1" spacer, or a ~1" shorter bolt.
Unless you get the 1.75lb aluminum bracket, only available on the MSM I think.
Someone needs to put a cast iron one on a decent quality scale and take a picture. Just so I can charge more for the aluminum one

oooh spiders!
I got my condenser out and put 100% distilled water with water wetter in. Hopefully I can say goodbye to 220* temps and always watching my temp gauge instead of driving!!
