Billet Oil Pump Gear set for the Nissan QR25DE engine
Factory oil pump gears are the weak point of Nissan VQ and QR engines.Poor design and material quality often leads to these gears failing, Thus resulting in total engine failure.
There is no comparison between billet steel and powdered steel used in OEM oil pumps. OEM oil pumps use a "cost efficient technique" called sintering because its cheap and produces tighter tolerances then casting. However powdered steel is even weaker then castings at only about 6000 PSI of strength. Good billet steels approach 110,000 PSI in yield strength or around 18 times stronger then OEM sintered steel.
Billet oil pump gears are a must have upgrade. Especially for high revving applications. Superior in design as well as material quality.
Billet gears are made of 4140 chromoly steel resulting in gears that are 15 times stronger than factory powdered steel gears. Another major improvement is the design. The symmetric design reduces stress by 30% when compared to the asymmetric design of OEM gears.
All billet gears are
are machined in matched sets, and shipped with blueprinting paperwork. These gears have been proven in applications of up to 1500 horsepower and red-lines exceeding 9000 RPM.
