Can I replace my stock ac with a smaller ac unit and what car should I get replacement ac from?

 

A/C unit???

What part, compressor, condenser, evaporator??? 94

 

The compressor

 

You can use any compressor you want.

There are three (3) issues you will run into...
1- Mounting, compressor needs to be mounted securely with pulley squarely lined up with crank pulley, [compressor also has to have the correct pulley].
2- Manifold fittings, either you have to find a compressor with the same fittings, [suction/discharge] as the stock fittings or you have to modify the lines.
3- Capacity, like just about anything a smaller compressor will not have the capacity of the stock compressor so "cooling" will be effected, how much will depend on a number of things.


So the question is, why? 94

 

My tensioner pulls broke and I'm trying to reduce engine drag

 

A smaller compressor will not help, the drag will be the same as head pressures, [A/C head pressure] will be about the same. 94
