TOMEI POWERED SUBARU STI EJ20/EJ25

Tomei Powered has begun research and development operations for the Impreza EJ20 engine beginning in 2003 and has been continuing until this day. In April of 2007, the full detailed specifications were determined for the EJ series complete engine. The ultimate objective of our research and development for these engine components is the assemblage of the complete engine.

Many hours are dedicated to engineering these products which make up the vital components of the complete engine kit. Features such as longevity and endurance are the major benefits brought to the end user of the automobile tuning industry.

In order to answer to the demands of the Subaru enthusiasts all over the world, we have decided to research the EJ25 engine, and proceed with the development of parts for this application. We have completed the first part of this R&D process, which is included in this report.
