Hello Paul,
What RPM and pressure does the oil injection pump run at on the 13B
series 5 engine.
I have a nice little pump that I may be able mount to the injector
pump flange that I will use to lubricate the PRSU.
This pump weights in at 1 lb

I think it is half speed Don. We figured it out once.
I will have to search the CD to be sure.

BTW it is easy to make your own gear oil pump using pinion gear stock.

Comes in different sizes.

Here is one I made. Worked like a charm.

Check the MAZDA OMP test procedure, and you may find out that you have to
use nano-technology to build a gear pump for that low flow rate. The MAZDA
spec  calls for 4.5 to 5.5cc on NA, and 5.2 to 6.6cc for turbo with the
engine running at 2000RPM for 5 minutes.

Hi Paul and Richard,
I am looking to use this pump for lubrication and cooling of the PRSU
only and not use the engine oil system.
