Can anyone confirm the engine in a 2015 Subaru WRX? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

This is from Subaru official website:

NEW 268-HORSEPOWER 2.0-LITER DIRECT-INJECTION TURBOCHARGED SUBARU BOXER ENGINE

Sounds like a turbo vision FA20 with plastic cover.

So anyone can confirm this?

Another engine pic

Yep, looks like an FA20 to me, based on what I can see. The oil filter is pretty much a dead giveaway, combined with the DI.

I am about 70% sure but not 100% that it is a modified FA20. You might see the detail in the image below.

Just cannot imagine that Subaru would waste money to design another 2.0 boxer engine.

It the FA20DIT. No port injection, and probably with lower compression pistons.

Spoke to the Subaru rep at the LA Auto Show and they said the direct injection was from subaru and not toyota..

hmong337 · 11-27-2013, 03:11 PM

waiting to learn more on this...

so no port injection? i wonder if anything pertaining the block and heads is actually different.

Yup. What we've got in the 86's is Toyota's hybrid DI/PI system, not a pure DI system like the non-collaboration Subarus.

That is correct. Toyota also filed Patent about using that together with Integrated Turbo multi-port.

I hear that WRX will use that FA20 with lower compression ratio and use their own DI, not the Hybrid one that Toyota have.

Subaru wanted Toyota DI system because how friendly they are with FI system, as Subaru already have Hybrid Turbo patented.

Regardless, you can still buy the whole setup and bolt it on to the BRZ....LOL. I am sure with how much the after market is doing to the BRZ nowadays. They will have no problem tuning it to 300 HP.

Though, don't expect the OEM set to be cheap. I am guessing in the range of 4-5k without labor

SirBrass · 11-27-2013, 03:33 PM

And it may not fit. The OEM configuration is set up for a TMIC, which is something that the BRZ's bay simply has NO room for. That also means it's a rear-mounted turbo, so there's NO space in the BRZ bay for that. You'd have to relocate everything and then retune as well as sacrificing the benefit of the collaboration FA20's high CR.

Better, I think, to spend about $5k-$6k with labor to go with a turbo or SC kit made for stock CRs.

Hazzard · 11-27-2013, 03:58 PM

Don't the Legacy and Forester have a 2.0 DIT with a turbo in front and a top mount intercooler?

ichitaka05 · 11-27-2013, 04:11 PM

Hazzard is correct.

This is FA20DIT. Same one as currently JDM Legacy 2.0DIT & totally different DI than our FRS/BRZ DI

I don't think Subaru would blatantly say its an FA20 because Toyota might demand royalties from the sales. However, FA20DIT might get Toyota away. I must say its not a pretty as our engine is.

Why would Toyota demand royalties? The only part of the engine design that is Toyota-based is the injection system, and this engine doesn't use the Toyota direct/port injection setup.
