bah, you don't need power steering on such a light car.
If i'm not mistaken, the 91 crx Si comes with power steering, or at least some did. A swap should be pretty straight forward, with hopefully not much modification

^this site says that all jdm crx's have power steering
oddly i wasn't able to find much on this...looks like this might be custom fabrication job...we all know how well jdm parts "bolt on"...
