I have a 500hp r34 gtr and I guess its time to upgrade the oil pump gears to something stronger that can handle rev limiter and shock.
I've been looking for billet gears and came over the plazmaman gears for about $380, but then I saw Reimax had some Chromoly steel gears for about $250 parts number: 15110-AAR11-81. How is the strenght on these? Anyone heard about these shattering? Is chromoly steel as strong as billet?
I have the oem 05u oil pump so the 81mm should fit?
