There's been a lot of
There's been a lot of attention to detail...just not attention to performance detail. Subaru as a company is really not on the performance game (and I can't blame them) - it's simply not as profitable as other segments. Now why didn't Subaru take the relatively simple steps with the EJ of: A) strengthening the pistons, and B) advocating an oil with better shear stability for superior bearing protection? - two things that would have probably saved them a small fortune in warranty claims. That I'll never understand.
The FA20 is newer, much more efficient, has a lower boost threshold and a powerband that is more usable for a street driven car, but no one has provided hard data on long-term reliability as far as I know. For that matter, Subaru's most capable cars (including their track cars) are still powered by the old 2.0 liter EJ20...NOT the FA, so there's not even a lot that can be said with race applications.
