Supposedly I read they were testing a 3.0 and breaking their 6speed tranny a few months ago now.. but yea we'll prob never see something that big. This news probably got mixed with the legacy line..
Correct, that's a legacy drivetrain you're talking about. A 3.0 liter turbo will not be for the WRX or the STi cuz the 2.5 liter had R&D money thrown at it, so the company needs to recoup that money. Second, as as mentioned before, a 3.0 liter would make the STi nose heavy and just kill the handling traits.
