I have no experience, but just out of curiousity, are you looking to do the electric motor driven hydraulic like the Subaru/Mr2 or the direct electric motor driven rack like the Hondas?
And IIRC vehicles as far back as the 80's(Fiero's maybe?) had such systems, you may be able to get your hands on those systems easier/cheaper than the newer systems.
