【OIL PUMP UPGRADE】
for RB26DETT
Newly designed case shape improves durability and oil flow amount. HKS Oil Pump Upgrade provides reliable oil supply for tuned engines.
FEATURES
- Larger rotor increases oil flow amount compared to the existing pump.
- New improved design now includes adjustable oil relief pressure (the alternator must be removed.). Utilizing outer shim enables adjustment to be visible.
- Thickness of driving rotor's contact portion is increased, and contact surface shape is optimized.
Thickness increase and material upgrade retain twice as much of rotor strength as the stock pump. - HKS Oil Pumps have reviewed the case design to retain sufficient rotor strength and to reduce oil flow resistance after applying pressure.
