What sort of revs can i get out of the stock oil pump setup?

[Turbo4L]

Hey guys does anyone know the limit of the stock oil pump, with the amount of revs we can take the motor to.
I would like to rev the stock motor to 8, but would like to know if the stock pump is as good a a stock 2JZ pump?

Cheers

I don't know the limit of the pump - maybe Erol can comment on that, but the design of the 1UZ pump is nearly identical to the 2JZ pump. I've had them both apart and compared them.

I don't know the answer to that, I have my doubts though.
RB26 Nissan's do split the outer ring, but we have an RB25 turning 8000 every day, has done 60,000 Klm and no problems. (says he with fingers and toes crossed)

Thanks for that, the tomei gtr replacement pump uses 2jz gears in them.
