9. Power Steering pump
Since the BMW originally had a pump driven off the engine for this, an alternative is needed. This Toyota MR2 power steering pump is a likely candidate:
All other components from the original power steering system will be used.
This is a late model spyder MR2 pump
When I tested the fit in the planned location, to my delight it fit like it was made for it. Luck happens..
The plumbing of the high pressure output aligns directly with an opening just below the chassis structure where it has a short and straight path to the steering rack hydraulic input. The low pressure return to the fluid reservoir, pointing to the left in this photo, can be pointed any direction which should ensure a good route path.
This inner fender panel completely encloses the pump.
It's visibility and access to the filler cap makes for a great location. This corner is accessible when the battery pack and the contactor box are installed.
Jan 2010 update:
The mounted pump:
With brackety oriented in both horizontal axis, the pump mount is very solid and has rubber isolation to prevent vibration in chassis.
The return fluid hose goes into a small mouse hole on route to return resevoir
I will detail the electrical drive for this when I get some time...
