So the FA20 @ 2L would be at 250 HP if Subaru went this way. Surely would be a pricey engine. Now if they took it to 2.5L, about the same cc per cylinder as the Porsche 4.0L, then we are talking 312 HP.
I agree that it should not be a turbo with weight penalty over the front end. Plus a NA engine has a better feel as it revs. Not that a torquey turbo engine is a bad thing, but I think it would be out of charactor for the BRZ.

That engine costs as much as an entire BRZ. I wouldn't say that is a good one to use when comparing engine stats to what is possible for this car.
If subaru creates a seperate trim line with more power and only finds 25 more hp, I would say that is a total waste. I wouldn't pay more than $1200 extra for that model which doesn't leave much room for suspension or brake upgrades. They need to add at least 50-70 hp along with the other upgrades to get real money out of me . Hell, they should pick up 20hp at the mid cycle refresh just through refining and tuning the engine as is.
