2008 Subaru EJ257B Component Development
Posted by Eric Hsu on Thursday, June 19, 2008We are working on the new EJ257B from the 2008 Subaru Impreza STi and have one on the engine dyno at the moment. Some components we are planning on testing and developing are the dry sump oil system, CNC ported cylinder heads, valve train, camshafts, intake manifold, and a couple other goodies.
It is a long hard road to design components that work. This engine dyno installation took us nearly 200 hours to design, manufacture, install. The test engine is using a Garrett GT35R turbocharger, TiAL 44mm wastegate, and Cosworth/Pi ECU. Our engine dyno cells are complete with 18" thick walls, climate control (temp, humidity), barometric control, and are complete with many, many channels of data acquisition. I'll post a tour of a dyno cell in the near future. For now, the next time you purchase a Cosworth product, you can be confident that your Cosworth component has been tested thoroughly for reliability and horsepower.
