Problems you'll run into with a different compressor manufacturer is going to be mounting it to the car, and keeping all the bits and pieces out of the way. If you decide to use a mounting plate, you'll need to make sure that there is a belt long enough to suit the extra length you would need. Also make sure wiring and air con hoses can run where you need them to without interference.
Is the car sr20? if so you could look at a pulsar compressor and then get it rebuilt before its put in.
I was going to private pm you soon so you answered my prayers haha. Thanks Kranzy. It's an SR20 so I thought about a pulsar air compressor. Realise about the longer belt etc. I just want to get a new compressor but that is able to be sourced easily and I was concerned about mounting. I was going to weld together a bracket but it may be easier (for a straight belt also) to stick with a pulsar compressor.
Do you know if the pulsar compressor fit the inlet and outlet fittings for our U12 pintara's. Or is my better option to go to the wreckers and get the inlet and outlet hoses for a pulsar and then my hoses from the condensor to the evaporator and dryer I can still use.
I am aiming to get this done for under $500. I picked up a good condensor and pipes for $50.
Also, is it possible to clean the pipes and condensor yourself or do I need to take it to a air con specialist
