Recent news about Subaru stated that Subaru is currently developing a 1.6 liter turbo engine & 2.0 liter turbo engine. I think there is a great possibility of one of both of these engines ending up in the BRZ at some point. Maybe not now, but most likely with a revised BRZ model.

What do you guys think? Don't forget to vote on the poll above before leaving a comment below!

Here's a couple articles about the 1.6L & 2.0L turbo engines from Subaru currently in development:

Subaru Working on 1.6- and 2.0-L Turbo Fours and Own Hybrid, Seeks 30 Percent Fuel-Economy Gain by 2015



At the Frankfurt auto show, we chatted with Subaru about its plans to drastically increase the fuel efficiency of its cars while maintaining their current levels of dynamics. The Japanese company says it wants to improve fuel economy across its lineup by 30 percent by 2015. New engines and revised transmissions will contribute to two-thirds of the increase, while lightweight body and chassis technology will provide the rest.



1.6- and 2.0-Liter Direct-Injected Turbos

Turbocharged, lower-displacement engines are today’s new hotness for achieving improved efficiency—Ford’s EcoBoost technology is the most marketed example—but for most companies, widespread turbocharging is new. Subaru, on the other hand, has extensive forced-induction experience and intends to put that knowledge to work. The new-for-2012 Impreza sedan’s new, naturally aspirated 2.0-liter flat-four is part of a new FB engine family (click here for a dive into the new engine), as is the Forester’s current 2.5-liter flat-four. While the 2.0-liter has boosted the new Impreza’s fuel-economy numbers significantly—the Forester saw only minor gains—Subaru plans to add direct injection (which we’re told nets a two-percent reduction in fuel consumption on its own) and turbocharging to the FB mix in the near future, both to the 2.0-liter and a new 1.6-liter variant.

Turbo BRZ? Maybe, but Not Yet

Ah, you’re thinking, this means a turbo version of Subaru’s sports car, the BRZ! While that hasn’t been explicitly ruled out—and we believe one is in the works—this isn’t a confirmation either. The engine in Subaru’s forthcoming coupe actually is codenamed FA, and exactly how it differs from the FB—likely only in its use of Toyota’s port- and direct-injection heads—isn’t known at this point.



Hybrid Coming in 2013

Furthermore, we learned that the FB will form the basis for a new, Subaru-developed hybrid system that will be introduced in Japan by 2013. It’s unclear if direct-injection, turbocharging, and hybridization will be utilized simultaneously, but for those with a long memory, Subaru’s Hybrid Tourer concept from the 2009 Tokyo auto show featured a 2.0-liter boxer-four with both direct-injection and turbocharging, a front-mounted motor/generator, and a second electric motor on the rear axle. Whatever form its hybrid system takes, Subaru plans on quickly spreading it to the rest of the world.

CVT Proliferation—Yippee

Subaru is extensively revising its Lineartronic continuously variable transmission, too, and will produce different variants tailored to engine torque levels—and that means more CVTs as a general rule. One variant will be bolted to Subaru’s diesel-burning boxer engine, which tells us at least one version will be on high-output duty. Even if the diesel never appears here, this is a strong signal that automatics in torquier mainstream Subies—our recently departed long-term Legacy 3.6R, which had 247 lb-ft of torque, used a five-speed slushbox—are likely to get replaced by CVTs. (The BRZ is one definite exception, as it will offer six-speed manual and traditional automatic gearboxes.) Beyond that, Subaru also is working to reduce friction and operating losses in its CVTs and all-wheel-drive systems to help achieve its efficiency goals.



Diets, High Strength Steel, and Lower Drag

Another critical part of Subaru’s aggressive plan involves lightening bodies and chassis components across the board. Saving weight is critical for Subaru and its AWD-focused lineup (the new BRZ will be rear-drive only), and so a new, lightweight platform that makes liberal use of high-strength and ultra-high-strength steels will be adopted. In addition to shedding weight, Subaru hopes to cut fuel economy’s other mortal enemy: drag. Subaru will be focusing more attention on aerodynamics than ever before.

What about those who cringe at the thought of CVTs? Besides provoking the response “just buy a stick-shift Subaru” from us, models like the WRX, STI, and BRZ still will exist and be geared towards enthusiasts, while cutting weight and refining their drivelines should ostensibly make them even better. If those cars’ survival—and Subaru’s, too—requires more CVTs to satisfy ever-tightening fuel-economy regulations, we can live with that—so long as a three-pedal setup is offered, too.
Edmunds Inside Line:

New Subaru Turbos Coming in 2012

Just the Facts:

- In 2012, Subaru will introduce two turbocharged variants of its latest-generation direct-injection four-cylinder boxer engine.
- One of the new versions of the FB engine architecture will be a 300-horsepower STI variant.
- The Subaru BRZ sports car will likely receive the turbo boxer engine, though not at launch.

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.

This is why I'm afraid of buying this car as soon as it comes out.
I'm sure they will have a stronger better handling version in a few years.

Its like that for all cars though. The new models are always better then the old models. Even a n/a BRZ should sell well. A turbo BRZ will just sell even better.

eventually a turbo BRZ model will be released, then Subaru will revise the whole model with new a new aero package, a better boxer engine, etc etc typical things like this might happen or something similar.

Yea, I'll probably hold off from by the first model in hopes that they make a turbo model. Unless a turbo engine can be easily swapped in, you might as well wait for Sti version or something while they work the kinks out of the first model.

Despite the reports of Subaru working on a turbocharged FA, I think it's far more likely that those boosted engines are destined for the 2014 WRX/STIs. If you look at the Inside Line article, and go on the speculated difference between the FA and FB (different head for DI), then it's easy to see that there's no room for a turbo since it's mounted below the engine.

what about on top with the pics of the motor it looks to have 4 to 5 inches of clearance and what about front lower right or left and i think in term would be less piping.

If they are developing a 1.6l that is a good sign that they will be getting back into the WRC. I too am in love with the BRZ but will probably wait for an sti version before making a purchase.
It took the US 3 years before the WRX STi came, I dont want to wait that long but I might have too. :(
