Oil Pumps

[Weissach911]

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.

With all the oil mods you will be fine, we use them as well as the GT3 pumps. just be sure you have a large enough scavenge out system to take full advantage of the larger pump.

The only issue we see with the magnesium 964 pump is a propensity for cracking.
If you choose to reuse a 964, inspect it closely for cracks in the pump body.
