Is it just me, or is there not alot of information about high performance oil pumps out there?
What are the top "tried and tested" brands? What should I avoid?, etc.
(for GSR B18C)

 

The purpose of an oil pump, obviously, is to provide lubrication to the various parts of the engine. The OEM pump is adequate to do the job.

If you are looking to replace a faulty pump. I'd suggest OEM. If you are looking to "upgrade" to a "high performance" pump. I'd ask why? More pressure could cause problems, not prevent them.

Maybe I'm all oil soaked here, so if I'm way off base, I welcome verifiable evidence to that effect.

 

Well I figure that since I'm boosting this motor, a higher flowing oil pump would be beneficial since the oil feed for the bearings is supplied by the engine.

Also, I heard that the OEM cast steel gears can shatter at high RPM's.

My oil pressure gauge read the same on my stock pump at 8000RPM as my Spoon pump did, so i'm not really sure if aftermarket pumps are really worth it.

Haven't heard about the OEM cast gear thing, so I can't comment.
However, a higher flowing pump without somewhere for the higher flow to exit would increase pressure to the point where oil would chose to exit throught the crank seals, etc.
