probably 200k plus mileage with zero service
Eventually it will happen
yeah, you'd have to imagine pretty extreme scenarios before something critical could possibly happen...

As far as tuning potential... the FA is already pretty cheap to bring into decent power gains. Not sure where exactly is the limit before you have to drop serious $ on the FA; but I'm pretty sure it's later in the power game than the EJ.
The EJ is cheap to bring into a 'Stage 2' setup but that's about it... from there on it gets really expensive. Doesn't mean the EJ is terrible. I like the powerband and character of the EJ far more than the FA.

But anyways... I would assume if Subaru puts a FAXX on the STI it would have a similar powerband. My guess is for next gen Subaru will drop a FA24 DIT making ~325hp, but with lighter stock wheels to bring 0-60 closer ~4.5s.

Sticking to heavy-ass wheels on the 2019 and 2020 makes their lives easier for next gen but direct injection is the way to go. No doubt.
