Turbo FA in the new JDM Legacy, next WRX

Turbo Version of Subaru BRZ’s FA-Series Engine Debuts in Japanese Legacy, Will Power Next WRX

May 8, 2012 at 12:35pm by Alexander Stoklosa
We recently confirmed that we won’t be seeing a turbocharged Subaru BRZ anytime soon; however, we now have a fairly good idea of what kind of power such a model will eventually bring. Subaru has dropped the first turbocharged variant of its 2.0-liter, FA-series flat-four engine—the naturally aspirated version of which powers the BRZ and its Toyota/Scion brethren—into the refreshed Japanese-market Legacy sedan and wagon.
The turbo FA20′s output numbers are impressive: 296 hp and 295 lb-ft of torque. In the JDM Legacy, the engine is bolted to Subaru’s CVT, likely for fuel-economy reasons; we’d expect a turbo BRZ to offer a proper manual transmission and an auto similar or identical to the one it uses now.

The new turbo FA features Subaru’s own direct-injection setup, as opposed (boxer-engine pun intended) to the BRZ’s Toyota-derived direct- and port-injection heads. We think the 2013 BRZ is pretty fun already, even with only 200 hp powering the rear wheels—close to 300 hp sounds like it would be silly fun.

• Instrumented Test: 2011 Subaru Impreza WRX STI Limited Sedan

Turbo BRZ uncertainty aside, we’ll likely see this engine appear on our shores within the next year or two under the hood of the next-generation WRX and STI. We previously confirmed that the sporty models will be powered by a turbocharged iteration of the 2.0-liter FA motor, and that the STI’s engine will produce north of 300 hp. The new 2.0-liter turbo four will replace the 2.5-liter turbo in the current 265-hp WRX and 305-hp STI. Although the thought of a 296-hp WRX and an even-more-powerful STI sounds pretty good, chances are the WRX will make something less than that, while the STI will make a little more. A big motivator for Subaru moving the WRX and STI to the smaller 2.0-liter turbo is, of course, fuel economy—the current 2.5-liter is thirsty. It goes without saying that more power and better efficiency for the next WRX and STI are good things. Now all we have to do is wait for the duo to arrive.

Sounding good to me

Interesting that they are using their own DI and not D4S. So a BRZ with a turbo in theory could make even more power by utilizing the dual injectors.

Engine & Transmission
- 2.0 liter Horizontally-Opposed four-cylinder DOHC direct injection turbo engine
Subaru’s own direct injection technology was adopted for the new generation Boxer engine. By injecting fuel
directly into cylinders, combustion efficiency was heightened, resulting in both high engine output and fuel
efficiency.
To maximize the effect of the direct injection turbo, the engine bore/stroke was made square (86mm x 86mm).
By employing the newly developed twin scroll type turbo charger with superior response at low engine speed,
high performance with high engine output*6 and torque*7 was achieved. This twin scroll turbo charger was
specially developed to meet the downsized engine capacity.

296 hp for the WRX is fine and more for the STi will be even better, but I want to see the new WRX soon.

Hopefully the engine will be a easy swap for those that want it and a Hella lot cheaper than a turbo kit me thinks

I think the turbo would be scraping on the ground. But it proves that the engine can handle the turbo, and with the BRZ's FA having D4S I think it will get even more power out of an FI kit.

Not for a few years it won't be.

[bimmerboy]

nice find!

However 296hp out of the 2.0 in japan sounds more like ~270hp by the time they de-tune the crap out of the engine to meet US octane and emission requirements....

Still would be absolute beastly in the BRZ though.. We all know its coming, just a matter of when...

Not Necessarily, look at the Turbo 1.6 DIT engine subaru makes, packaging looks like it would work with the BRZ. It is much different packaging than the old EJ series turbo motors:



"Though there are no claims this will go in the 86, it doens't take much imagination to see it being done, either by them or by us. This turbo packaging is very friendly for the 86's FR layout, since there will be tons of room in front for a bigger turbo. This packaging makes a twin-scroll a no-brainer, since you could essentially have the same manifold as the non-turbo engine, but with a turbo flange right after the 4-2 collectors. It would also be much easier to simply put the intercooler in front, where it belongs, and connect to the already forward-facing throttle body. It's not clear how Subaru is dealing with oil drainage, since the turbo's oil drain is down below the oil line in the pan, but the fact that Subaru already worked it out for us makes it much easier when we turbocharge one of these ourselves.
The dual direct/port injection system now makes perfect sense. It's easier for tuners to leave the direct injectors alone and add bigger port injectors for boosted fueling. "

Even with vehement denials of a boosted Subaru BRZ, Subaru has still managed to debut a turbocharged version of the 2.0L Boxer engine. And just because the BRZ won’t get it doesn’t mean other products won’t.

Set to debut first in the Legacy, the new engine makes 296 horsepower and 295 lb-ft but comes mated to a joyless CVT gearbox. Womp womp!

The FA20 Turbo motor does away with the Toyota D4-S system and gets a true DI system instead. Expect this engine to appear, with a manual gearbox, in the next generation WRX, and perhaps in a higher state of tune for the WRX STI. And who knows…maybe it will end up in a turbocharged BRZ, or Scion FR-S.

There you go, even though it's CVT and looks like the bottom end sits too low for the BRZ.

[Subaruwrxfan]

Interrrrresting...296 hp too, wow.

[Chenslee]

Mash, wait, BOOST, ditch. I'm holding out for a supercharger.

[Dark]

Awesome. Can't wait to see what the next gen WRX/STI will be like.

[ZetaVI]

This intensifies my anticipation of seeing a new WRX/STI. I want it revealed real soon.

Makes me wonder what the hell they're going to do with this motor...

Either a Sport Impreza (since we hear the WRX will not be Impreza based anymore...) or a BRZ STI?

I wouldn't mind a smaller AWD 3 or 5 door hatch from FHI with that motor either... (You know, one with short overhangs and wheelbase, lots of suspension travel, strong chassis, WRC suitable...)

Say ~235hp/200tq...

[ichitaka05]

It's cool & all but it's not FA engine... I think, they just tuned FB engine into turbo w their own DI.

Ah~ whatever
