I'm dealing with power steering parts sourcing right now. Sublime has the pressure reducing valves, but refer you to Turn 1 steering on their page for the flow control valve. Unfortunately it looks like they are out of stock. I had planned on getting the pressure reducing valve from pull a part, but there aren't any cars there right now that would have the valve I need. I guess I'll just get it from Sublime and call turn 1. From what I've found online, the steering rack wants 850 psi and 2-3gpm.
