PBMS Oil Gallery Modification

Having experience with Subaru EJ engines since production began in 1989, PBMS know all there is to know about them. An inherent weakness is the big-end bearing and lubrication design.

We have developed an engine building process that greatly improves EJ engine reliability, based on hundreds of motorsport engines built over two decades.

A key part in building a reliable EJ engine comes from the PBMS Oil Gallery Modification. Using insider knowledge, we modify a number of oil passages in an engines block to provide optimal oiling to the big end bearings.

PBMS Oil Gallery Modification – $599

CNC Closed Decking – Subaru EJ

Another weak point of Subaru engines can be the deck design. PBMS have developed and refined a solution with a CNC Closed Deck 2.5 and CNC Closed Deck 2.0.
