Might have some oil leaking from the CPS O-ring (where it fits in the head) down to the manifold....those get dried out and crack. Where you described is about the right place.
I used an OEM pump and shimmed it with 2 washers (~3mm)...engine warm w/ 5W-30, that gives me 15 psi at idle and 40 psi at 3000+ rpm.
My thought on a "hi-volume" pump is that there is two ways to get additional oil flow...volume or psi (or rate). With volume, you are still going to be...

A friend of mine got one...he said it was basically an OEM pump.
No offense taken...it's funny though cause I've personally seen two with the equipment that can do it and the RA meter to prove it. Both were in the 20-30 range.
Not too sure where you got this statistic, but there are several machine shops in my general area (dozens in the Phoenix Metro area) with modern machines...getting to the RA spec is no problem at all. And if you want it really smooth, a machinist with a lapping table can make it like a mirror.
Yeah...I agree. A 3000 rpm stall would be just about right.
The ones I've seen fail were past the 350 crank HP point. Doing burnouts with it will hasten the demise ;)
Yep...and you'll vent gas fumes out next to a hot turbo. Can you say "flame on"? If you block the vent line from the tank, pressure builds up...not good either...you would have to drill a vent hole in the gas cap.
The charcoal cannister has no effect on gas milage...it's actually part of...
