I have a 964 oil pump which is marked: 964.107.130.7R.
I believe that this a magnesium bodied high volume pump with an improved scavenge.
I am considering fitting ot to an early 2.0 magnsium crankcase on a motor we are preparing for a race car but I seem to remember some comments about high levels of expansion causing problems
with this pump but can't find the old thread.
I know that the case will need a small mod and we will do the By-Pass modification, I also know that I will need to change the coupling for a short 964 component.
Any other comments welcomed.
