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.
NITTO RB series oil pumps are supplied pre-inspected, blue
printed, assembled and cleaned to enable direct installation
straight onto your engine and assure total confidence.
