Cosworth Dry Sump Setup Kit for Subaru EJ engines

ej-dry-sump-kitThe Dry Sump Setup Kit for the Subaru EJ series engine now available from Cosworth is a must for race and performance applications.

Dry sump oiling systems offer an unparalleled level of safety and reliability compared to factory Wet Sump systems. Complete crankcase oil scavenging reduces excessive and residual oil that can cause blow-by and power loss.

A dry sump also offers more consistent oil pressure to the engine, improved scavenging, and increased ring seal due to greater pan vacuum.

The Cosworth Dry Sump System for the Subaru EJ20/EJ25 replaces the original oil sump with a machined from solid, low profile alloy pan with twin scavenge ports, internal baffling and o-ring sealing. A two stage scavenge pump driven by a HTD belt, mounted to a heavy duty bracket evacuates the oil from the engine.
