It seems to be less of an issue on the STi, not as sure about the wrx. I believe it is the 2.0L engine that runs into the problem more so than the 2.5L boxer. Very rarely do I ever see anything about this topic, I had to go look it up. Quote from somewhere:
"Cylinder number three - the one nearest the turbo - is almost invariably the cylinder that gives trouble in GC8s. There are numerous theories, but it seems the problems are linked to lean mixtures and/or detonation in that cylinder. Number three is the last cylinder to receive fuel from the rail and we've heard any drop in fuel pressure means it starves."
