It really doesn't help to much, I was wandering down that path a while back and just took off the ps belt. The result was not that impressive at all, the z didn't really rev faster and definitely didn't seem to accelerate much faster. Not to mention other cars with say electric assist steering had lighter engines sitting on top of the tires that requires less assist to turn said tires. Just my humble opinion, but if you must, I've read a few places about using part of the setup off the mr2 in conjuction with our rack. That's all I'm gonna say, if you realy want to do this you can find the writeups :)
