RCM Roger Clark Motorsport

Cylinder 4 cooling has long been a known issue on the EJ Family of Subaru engines. The nature of the water passageways around this area means a lack of cooling can lead to an increase in the temperatures around this cylinder.

RCM's simple solution to this problem lies in our easy to fit complete kit. Billet fittings are banded in place on our custom 90 degree Samco silicon hose, which you simply fit into the unused port at the back of the block at cylinder 4's location. This is then tee'd into the water matrix pipe directly above using the supplied HiGrip stainless steel fittings. The billet barb fitting is of the correct diameter to allow the right flow rate around cylinder 4 to cool without over cooling, and the 90 degree pre-formed Samco hose ensures that this flow is maintained without disturbance from potential kinks in the pipework.

Suits all EJ Engines

The RCM 340 uprated fuel pump kit should be one of the first things you consider installing when modifying your Impreza above stock power levels, as the ability to provide your engine with enough fuel is crucial to performance.

The RCM340 is a high output, in tank, electric fuel pump that directly replaces the standard fuel pump assembly within the fuel tank. With the ability to supply an impressive 340 litres per hour of flow, this kit comfortably out performs other Impreza pumps on the market and is a huge improvement on the standard fuel pumps. 

Ideal for Imprezas developing up to 500bhp and with straight forward fitment via the inspection cover on the cars floor pan, the RCM340 offers superior flow throughout a wide pressure range. With unmatched durability and reliability thanks to its turbine pump mechanism and 30% better performance when compared to its rivals, RCM recommends this pump as a great upgrade for the standard unit or even other popular fuel pump kits on the market.

This pump has also been designed to cope with the New Age Imprezas oscillating voltage supply. Feed to the pump varies from 8v to 12v depending on how the car is being driven.
