Looks to be a face lift with some suspension and center differential changes. STI still rocking the EJ257, new motor never.

A few of the changes:

- Revised suspension tuning
- Driver Controlled Center Differential (STI only)
- Brembo monoblock calipers (6 pistons in the front and 2 in the rear, STI
only)
- Larger-diameter rotors are cross-drilled for better heat management (STI
only)
- 19-inch alloy wheels wrapped in 245/35R 19 tires (STI only)
- Recaro® performance seats (Available on WRX Premium, WRX STI and
WRX STI Limited)
- 6.3-inch multifunction display with turbo boost gauge
- LED Steering Responsive Headlights (WRX Limited and STI Only)

JDM STI even gets a better 2.0L EJ engine that pretty much makes the same power as the 2.5L they give us.

Why they haven't come out with a bigger displacement of the FA20 engine till now is maybe it's not a good engine and they would have to seriously rework it to be on par with all the other crazy 4 cylinder cars RS/CTR/AMG and even Golf R which is conservatively factory tuned but is a simple flash away from HUGE gains surpassing what the EJ25 is capable of from stock before blowing up.

Even Porsche "downgrading" from a Flat 6 is showing Subaru up with a more potent 2.0 and 2.5 boosted flat 4.

"The same flat-four cylinder engine that powers the roadster can also be found in the 718 Cayman. In the standard configuration you get a 2.0-liter engine that delivers 300 horsepower, and 280 lb-ft. of torque over 1,950 and 4,500 rpm. The Cayman S naturally gets a 2.5-liter engine with 350 horsepower, and 309 lb-ft. of torque. In both cases, these 2017 models get 25 more horsepower than their respective predecessors. Is it any wonder, then, than Porsche decided to name them after legendary 718 race cars? The 718 Cayman, can go from 0 to 60 mph in 4.5 seconds while the S model does it in just 4."

They released the new facelift news on these a few months ago, so this isn't technically new news...however I agree with the other commenters and OP about the engine upgrade. I literally know a few Subie fans who are leaning towards RS right now instead of the STI because of how ****** behind they are with the motor. Like seriously? They are making 0 attempts (that they've made public) to try and update it. An aggressively tuned (maybe bored out?) version of the motor in the WRX currently would be WAY better than the ancient motor it has now. With a tune the new WRX spanks the STI and if you look at Dyno numbers it actually beats it until they hit 4k rpm and the STI's turbo finally picks up the pace. At this rate they might as well discontinue the STI as it's own model and just improve the WRX

I don't even think they need bigger displacement for the FA20. Just give the STI a bigger turbo with it!

That would be a sure way to advance it's abilities, but it would cause too much stress on the car for it to reliably last as long as the current car does stock. Hence why Ford and other companies doesn't just throw a bigger turbo into the ST/RS/etc vs putting bigger motors. They have to also maintain fuel efficiency, each MPG lost could mean someone's business.

I could be mistaken but wasn't that the way they did it with the older wrx's and sti's though? Before 2015?
