Product Description

The HKS 15003-AN002 is a reinforced oil pump upgrade built for the Nissan Skyline GT-R's RB26DETT engine (BNR32/BCNR33/BNR34), featuring an enlarged rotor that boosts oil discharge to 65 L/min at 6,000 RPM - a 38% increase over the stock pump. This added flow supports the higher oil demands of built, high-boost RB26 engines.

Relief oil pressure can be adjusted without removing the oil pan (though the alternator must be removed for access), and an outer shim adjustment system makes the pressure setting easy to visually verify. This version specifically includes a pre-machined clearance notch for HKS's crank angle sensor conversion kit, allowing that upgrade to be installed without any additional modification to the pump.
