I did away with my ac compressor and ac unit from under dash as well, was a royal pain in the butt. A/C unit under dash is huge and not as weighty as i thought but still counts, power steerubg pump gone as well, i must say i do get a better feel for the car without p/s i feel EXACTLTY what the car is doin. i recently got my car weighed, 2660 with me in it 2460 without

 

I did this mod months ago and when i also did my exhaust and intake everything felt that it was now working together perfectly. your RPM's climb so much quicker. but dont get the ebay generic brands, those start to shake after awhile

 

just put it on today and its a piece of cake!!
all u need is air air tools
took me about 20 mins!!
