The NITTO high volume oil pump is a high quality performance aftermarket oil pump that will suit Nissan SR20 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.
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 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.
