As stated above I'm after the pump pressure.
Short version.
I need shoulder surgery, to young to get rebuild so told to wait till I'm older.
Manual steering hurts shoulder bad.
Have purchased power steering for e21.
Have m52 with PS complete.
What are the pump pressures between the two pumps.
From what I can find the e21 is 1000 and the e36 is 1200. This will make my steering very light and I don't want that
