Stage X 4 Stage Dry Sump System with Head Scavenge EJ20/22/25

A reliable oil supply is a key concern for any Subaru EJ engine tuned for performance or race use. A dry sump system offers a level of safety and reliability that cannot be matched by a standard or even baffled wet sump.

This system completely scavenges the crankcase, which greatly reduces the residual oil left in it and ensures the maximum amount of oil is returned to the tank at all times. The kit also has additional ports so the cylinder heads can be scavenged.

It delivers a far more consistent oil pressure to the engine, eliminating the oil starvation associated with the flat-4 boxer layout. The stronger scavenge effect in the crankcase also improves ring-to-bore sealing.

The system has 3 scavenge stages and 1 pressure stage in a compact layout specific to the EJ engine range, and it can be installed without removing the engine from the car.

Fits EJ20/22/25 engines. Separate kits are available for the Subaru Impreza GC8 & GF8 and for the New Age Impreza 2001-2007.

Water pump kit included

The kit includes the Stage X Black Series 2 port water pump kit. Its corrosion-resistant satin black finish is designed to absorb excess heat, which is then circulated into the cooling system. Water is pumped around the engine by a cavitation-friendly cast impeller, maximising flow without unwanted aeration.

The pump also has a corrosion-resistant billet aluminium thermostat housing for smooth and efficient coolant movement.

• Water pump gasket
• Thermostat seal
• Thermostat housing and bolts
• Pump housing bolts

For the best performance and reliability, use it together with the Stage X dry sump under-bonnet installation kits.
