wondering if i need to replace my oil pump on my Neo Rb25i know they fixed the problem and i'll only be running 10lbs max on stock turbo...

...should i replace it for piece of mind or hold off until bigger turbo, upgrades, i.e. more stress on the motor

thx

No need to replace it. Might want to take the pump off to verify that you have a good crank snout/pump drive. I think Carl was saying that some early model R34's even had the bad crank snout?? I might be remembering that wrong though.

I have a neo crank in my garage out of a buddy's neo that he blew. It has the bad oil pump drive.
