The Oct. issue of ‘Import Tuner’ magazine talks about the Subaru boxer engine at how we get the growl of a V8 but the sound of a 3 cylinder engine. They directed it toward the WRX, but I’m sure the EJ25 works the same way. They said that our engine fires @ 1-3-2-4, but our engine is set up with cylinders 1&3 on one side and 2&4 on the other side. With that said, it doesn’t work like it’s a full engine, but two separate two cylinder engines in one block. Although that may sound interesting, I don’t know for sure if our engines work like that. What’s the difference if the EJ25 fired at 1-2-3-4 (making it work like a whole 4 cylinder engine)? I’ve seen a video of an EJ20 sti engine internally working and it doesn’t look like it’s pumping the way ‘Import Tuner’ wrote.
