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
