You want to remove the air conditioning compressor? On all the 6cyl cars I've seen that have AC, it drives the alternator via a short belt around just the alt and AC compressor. It could be challenging to delete the AC compressor.
If its the smog pump "compressor" you want to take out, then that's a different story that I just don't recall info about.
We need more info about what your car has and what "compressor" it is you want to remove.
Also, if you are not using the AC, it just serves as an idler pulley, sucking negligible amounts of power.
You want to free up some power, get an electric radiator fan to replace the mechanical one.
