Why the EJ22T?
The semi-closed decks motors are arguably just as strong.
They are more supported (pistons, rings, cranks) because of the 'odd' bore size and the #3 thrust position.
Power potential is greater with an EJ25 sized bore, regardless of chosen stroke length.
2.0 bore fits 2.0 heads better than 2.2 bore. Same goes for 2.5 bore and heads. 2.2 only ever got SOHC heads (outside of the oddball 22B cars, which had EJ20K heads)
10 years ago, I could make an argument for an EJ22T build. But now, with the semi-closed decks available, the best argument is nostalgia.
Disclaimer...I am hoarding 4 EJ22T blocks ATM. I am a first gen Legacy guy, and for me IT IS nostalgia. Not all of my Legacies will use them, but at least one will "because that's where they belong". I have built, and love, an "old school EJ2.35" using the 2.2 block/bore and a 2.5 stroke/crank. If I was to build it again, it would be a "new school EJ23" using a 2.5 bore and a 2.0 stroke. I'm hoping that the perception that they are better than newer blocks holds until I can sell them for a complete STI/LGT (basically AVCS) conversion for one of my first gen Legacies.
