Delivery Information


At the heart of all Roger Clark Motorsport engine builds is the now world renowned RCM Modified oil pump.

This clever, effective modification has been designed to assist the Impreza with its oil supply issues 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.

Please note that flow rate remains unchanged.

Our 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 (SGA35) to seal the oil pump to the block assembly.

• Modified with a billet, super finish, nitrided replacement plunger.

• 10mm Internal drive rotor.

• Serial numbered.

• Primed with oil prior to dispatch.

• Improved reliability.

• Carefully Inspected and primed with oil prior to dispatch.


All Impreza Turbo's 1992-2015.
