HKS OIL PUMP UPGRADE RB26

The HKS oil pump upgrade for the RB26 engine features a larger internal rotor and housing, increasing oil flow capacity by approximately 10% over the stock unit. This is a critical component for any RB26 build pushing beyond factory power levels, ensuring adequate lubrication under demanding conditions. Maintaining proper oil pressure and flow is essential for engine longevity, especially when dealing with increased RPMs and higher operating temperatures common in modified engines.

This well-built unit is designed to be a direct replacement for the factory oil pump, simplifying installation. The increased flow rate helps to combat oil starvation issues that can arise from increased engine load or modifications like oil coolers. By providing a more robust oil supply, this HKS pump helps protect vital engine components like bearings and camshafts from premature wear. It’s a solid choice for builders who understand the importance of a reliable lubrication system when aiming for significant power gains.

When installing this oil pump, it's recommended to inspect the oil pickup tube and screen for any debris or damage. Ensure all sealing surfaces are clean and use a quality RTV sealant or gasket as specified by HKS installation instructions. This upgrade is a key part of a comprehensive engine build, working in conjunction with other components to create a powerful and reliable powerplant.
