Yeah, pretty strange they went that way. I thought I read initially that the rods and pistons were forged.
Kind of makes me want this less now.

It's a bummer that there won't be forged pistons. I wonder if this means that it's the same internals as the RA/19+ STI?

Subaru had to quash its ambitious plans for forged pistons and connecting rods, due to potential durability concerns that the company now suspects was a non-issue. Nevertheless, Subaru ultimately decided to take no chances with this special, high-profile car, and went with cast components instead, with no resulting loss in horsepower.
New upper "rear draw stiffener" with a cherry blossom cover?



The top handling priority was to reduce the WRX’s “hysteresis,” a fancy engineering term for the time lag between turning the steering wheel and the car’s attendant reaction. Subaru says the S209’s steering yaw response is 15% better than even the Type RA, itself a veritable waterbug of a sedan. So-called “draw stiffeners,” developed on the brand’s Nürburgring racers, connect the lower front suspension arms to the body crossmember. A sophisticated, flexible front tower bar improves cornering and straight-line stability. Another damped draw stiffener again preloads the rear suspension for faster steering response and improved cornering force. There’s a new rear subframe brace, and spherical suspension joints that increase the tire contact patch by as much as 20 percent under duress. Bilstein dampers, stiffer in compression but softer in rebound vs. the Type RA, mate with 10-mm lowering springs.


There's a second flexible draw stiffener in the trunk, too, protected by a pink bar so that owners don't accidentally smack the thing when loading up the trunk.

The pink bar itself doesn't do anything other than protect the actual draw stiffener behind it. Better safe than sorry.
Lots of bracing. Hopefully some of these "JDM" Subaru Japan parts will be cheaper now they'll be available via local dealers in the US.

The forged pistons were a huge selling point.

I just went to re-read Subaru's press release from back in January and the link is dead now. It worked a couple weeks ago.. Even the link from Subaru's website is bad. I wonder if this is one of the reasons they pulled it.

Hmmm that's strange. No special pistons and balance rotating assembly like the usual S model eh...

I noted they pulled the forged internals and pretty much checked out afterwards. There's no doubt this will be a special STi, without a doubt, but I definitely am disheartened to hear they elected to do so.

To me, this is clearly an attempt to keep the cost of the car down and I genuinely expect the S209 to check in around $60k and the markups will most like start between $5-10k - easy.

All 209 will be gone faster than I even want to try and comprehend.

There's an RA in SC, about 3 hours from me. 3 miles on it.
I told my local dealer to call me immediately after the truck gets there with their S209.
Now I'm kinda doubting myself from getting it. I remember all the people that spent big money on the RA only to find out the regular STi was extremely similar.

I'd love to see that odometer, here I thought I was on it with 7.1 xD

There was someone that recently purchased a used Type RA with 5k miles for ~$42k. I'd definitely go that route to save some money.. especially if you have any intention of modifying. You can always buy the S209's chassis bracing if you really want it. Throw on some better tires and you probably won't notice much of a difference.

The S209 will still sell out quickly because of its name and rarity.

I'm SatinWhitePearl from Nasioc, was just replying to you over there. :lol:


I wonder what mine would fetch in factory plastic and 7.1 miles - hmm? :lol:

The RA and 19+ STI have the same internals.. at least the short block. Subaru specified that the RA has sodium filled exhaust valves, but didn't mention that for the 19+ STI engine.

The valve set part #s are different for 2019.. both from the '18 STI & '18 Type RA.

2019 STI
11018AA930

Nope, but they're strengthened. :tup:
I've seen a few tuners comment that the strengthened internals are much more "reliable" at the 400 whp level.

What does that even mean? They thought forged pistons would be a problem, now they don't, but they went with cast anyway? I assume the rods are still forged... WTF is Subaru doing? This car needs to have forged internals.
