Note: Nitto RB oil pump NIT-OIL-RB26 is the same pump as the one here NIT-OIL-RB26SINE but with one difference that the inner cog is different and that it also includes the SINE Cog (NIT-OIL-COLSINE).

Suitable for on off on off application reffering to 800+1000+ HP Circut/Drift cars, why because the gear will handle alot more abuse than a flat drive gear will. I could try to explain it more in words but your better off watching the video below to understand the difference between the normal flat drive and the new sine drive gears.
 

The NITTO RB series high volume oil pump is a high quality performance aftermarket oil pump that will suit Nissan RB20, RB25, RB26 and RB30 engines.

Oil flow and pressure is dramatically increased over that of the factory oil pump which is critical in modified engines for reliability of the lubrication system. Failure of this system is the “Achilles heel” of the Nissan RB series engine even on mildly tuned examples and accounts for a high percentage of ”RB” engine failures.

Factory based oil pumps are highly prone to oil pump gear failure in modified engines due mostly to the quality of the cheaper mass produced material used in the manufacturing of the OEM style gears. Oil pump gear failure will result with inevitable engine damage. For this reason EN Series billet steel material is utilised for the manufacture of NITTO RB series high volume oil pump gears which are far superior in strength and durability to that of both factory and its competitor’s oil pump gears.

NITTO utilizes their precision CNC machined cast alloy outer housing and along with their already proven oil pump design NITTO has now released a new billet alloy backing plate allowing further stability to oil pressure and flow at high rpm levels by minimizing any possible flexing of the housing.
