Product Description
This 4-stage dry sump system is designed for the Subaru EJ20, EJ22 and EJ25 engine range. It fully scavenges the crankcase to reduce residual oil and help maintain more consistent oil pressure, with additional ports allowing the cylinder heads to be scavenged.
The system uses 3 scavenge stages and 1 pressure stage in a layout designed for the EJ engine range, and can be installed without removing the engine from the car.
The kit includes an RCM Black Series 2-port water pump kit, featuring a satin black finish, a cast impeller, and a billet aluminium thermostat housing. Also included are the water pump gasket, thermostat seal, thermostat housing bolts and pump housing bolts.
This system is designed for use together with RCM Dry Sump Under Bonnet Installation Kits.
