Is there a differences between euro and U.S. cvh oilpumps? Would U.S. oilpump have more capacity?

I'm building a 1,3 litre cvh with turbo, ic, megasquirt etc. and i put bmw oiljets on the block to cool pistons (i will be running at beyond 2bar :twisted: ) and i just wonder if my oilpump doesn't have enough capacity to pump enough oil presure anymore, where i can get more powerfull oilpump..
Many dealers sells high presure pumps, but they are just stock pumps with stiffer spring in bleeder valve.. no use in my case.

I will at least try on stock oilpump, i'm just wondering do i have any other options..

I just measure the euro oilpump inside gearings. It was 100mm or abaut 4" in diameter and 8mm or abaut 1/3" thick.

If someone, sometime, unscramble U.S. oilpump and can put measurements in here, i'll be gratefull
:wink:

Our cvh's have a quite poor oil presure when idling, 10 to 16 psi when hot, and cam wear proplems are quite usual..
