FRANKFURT, Germany — In 2012, Subaru will introduce two turbocharged variants of its latest-generation direct-injection four-cylinder boxer engine, including a 300-horsepower STI version.
The new FB engine architecture, first launched in the U.S. in normally aspirated guise in the 2011 Forester, will add boosted 1.6- and 2.0-liter variants next year.
Yet to be determined is whether the boosted version will find its way eventually into the new Subaru BRZ sport coupe. So far, Subaru is only talking about a normally aspirated version of the new 2.0-liter boxer engine for the BRZ, a variant of the FB architecture known as FA. The FA engine in the BRZ is understood to produce 200 hp and employ Toyota's D-4S direct- and port fuel-injection layout, though company officials would not confirm these widely held notions.
On the force-fed FB variants, the turbo is mounted beneath the engine, in contrast to the high-mount location typical of the turbo EJ-series engine still used in the U.S. The intercooler remains mounted directly above the engine.
In STI guise, the new 2.0-liter FB turbo is targeting the same 300-hp peak output as the existing engine, but will return 10 percent better fuel economy.
Inside Line says: Look for more details to emerge when the production version of the 2013 BRZ is formally unveiled in December at the Tokyo auto show.

I don't care about the BRZ. Put a de-boosted version of the FB engine in the 2012 Forester XT with this new 6 speed and upgrade the interior. 4 Speakers!? Are they even trying? The 2011 does not count as a refresh.

Subaru has already confirmed that it will be a 6 speed Manual and 6 Speed Auto. If there is a turbo, it goes against anything Subaru has said to this point, but I have to think that there has to be something that seperates the Scion from the Subie

The 4 speed is history and most NA engines will get either CVT or Manual. Not sure if they will make a auto for the turbo, but I would love to see a standardized 6spd man.

So the FA engine is making 200 hp from 2.0 liters, so adding a turbo to get the FB for the STI brings it up to 300 hp. I don't think Subie will want to do this as it might out perform the STI. So, any guesses as to how much hp is available from the 1.6 liter FB turbo? This might be a better fit for the BRZ with two wheel drive anyway.
And any news on curb weight for the finished car? I seem to remember around 3000 lbs, but that would mean they missed their weight target, wouldn't it?

What Subaru needs to do is axe its ridiculous *4* speed auto.

I agree with hotrodw - Subaru better not saddle this new motor with the 4-speed automatic. How hard can it be to put a modern transmission in a Turbo Forester?
