Why do you want to get rid of it? It's not heavy like a hydraulic PS system is. You'd definitely need PCM work as I'm sure it's controlled through it.

It actually is quite heavy. Crawl under your car and look at that thing. It's huge. It's very similar in total weight compared with a complete typical fluid system. It's a much cleaner setup, and I'd sure love to have it on mine, but lighter it's not by much. If really trying to save weight, a manual rack is the way to go. I don't know what problems that may create on the new cars though.
