RCM 11mm Modified Oil Pump
At the heart of all Roger Clark Motorsport engine’s is the renowned RCMS Modified oil pump.
This clever, effective modification has been designed to assist the Impreza with it’s oil supply and is now regarded as a must have modification with any Impreza engine build. Each pump is carefully checked, given a serial number and then modified to incorporate a different pressure relief valve ensuring greater reliability and peace of mind to your Impreza engine.
This variant of oil pump is fitted with the larger 11mm Rotor meaning a higher oil pressure is produced, perfect for modified engines where components require superior lubrication.
These oil pumps are supplied with a replacement front crank oil seal and oil gallery, black sealing o-ring. It is also recommended that you use 3 bond sealer to seal the oil pump to the block assembly.
