Import Tuner Article – The Truth Behind The Subaru EJ-Series Engines

Subtitled, “Are they as weak as tuners claim?”

Subaru engines have always been known to be well engineered that are both powerful and torquey, but Subaru engineers left a lot to be desired when it came to the EJ205 (’02 to’05 USDM WRX), EJ255 (USDM WRX ’06 to present) and EJ257 (’04 to’07 USDM WRX STi) turbocharged models. This month, we get in-depth with three of the top Subaru tuners in the world, as they help dispel myths and speak their minds about the infamous EJ-series engine.


Mod Notes – this is a great read.  It’s not too technical but technical enough to give you an appreciation of the Boxer engine layout.  I found the article posted at http://www.iwsti.com/forums/3816681-post405.html (titled, “defend against ringland failure”)…this is a Subaru owner must-read, IMO.
