Description

The newly designed case shape on the HKS oil pump upgrade for skylines improves not only durability but also oil flow amount. The new HKS oil pump upgrade for skylines provides reliable oil supply for tuned engines. Meaning, some tuned RB owners may need an upgraded oil pump as an essential upgrade. When increasing the amount of boost on your vehicle, don’t forget about the oil pressure. The HKS Oil Pump Upgrade will increase output by nearly 50% on average. We’ve included some metrics below.

• 600RPM – Stock 3.7 L/min – HKS +5 L/min
• 2000RPM – Stock 12.9 L/min – HKS 17.3 L/min
• 6000RPM – Stock 39.9 L/min – HKS 53.1 L/min

• Fitment:
• 1989 – 2002 SKYLINE GT-R

Larger rotor increases oil flow amount compared to the existing OEM pump. A new improved design now includes adjustable oil relief pressure (although, 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.
