could get either a 2.5 light/moderate-pressure (would be my guess) turbo, or an H-6, depending on what Subaru thinks would be most appealing to that market. My guess would be the H-6, as to I think that would appeal most to that type of customer. In any case, I would guess somewhere around 230-240 HP.
I think the Baja will get whatever turbo engine the Forester gets.
There is also that persistant rumor of a new "flagship." My guess is that will have (at least) 6 cylinders, and probably a turbo, at that.
