Japan is the only country to get this WRX S4 tS

Before the Impreza switches to a new platform, Subaru is wringing more limited editions out of the old one. The most recent, the Subaru WRX S4 tS, is a Japan-only special that is based off of the WRX S4 model released a few years ago. Underneath the hood, the WRX S4 tS gets the same modified 2.0-liter turbocharged flat-four from the WRX S4 that generates 296 horsepower and 295 pound-feet of torque. The modified engine produces 28 horsepower and 37 pound-feet of torque more than the standard WRX, and is only five horsepower off the turbocharged 2.5-liter Boxer engine in the WRX STI, while making more torque. The handling has been improved thanks to a similar setup to the one on the WRX STI S207, another Japan-only model released last year, that features adjustable DampMatic II front suspension from Bilstein, along with other goodies. The exterior gets 19-inch BBS forged aluminum wheels, red pinstripes on the front grille and rear bumper, and a large front spoiler. On the inside, the WRX S4 tS benefits from Recaro bucket seats and a luminescent speedometer. The sedan is also equipped with Subaru's advanced safety features in the form of EyeSight. Japanese enthusiasts can also choose a more hardcore option with the NBR Challenge Package that commemorates the automaker's victories in the SP3T class of the Nurbrugring 24 Hours in 2015 and 2016. The sportier model gets 19-inch wheels from BBS, a carbon-fiber rear wing, special badging, and a suede-lined steering wheel on the inside. We reached out to Subaru to see if the vehicle would be sold in the US, but the spokesperson refused to comment. With the WRX S4 and the S207 being Japan-only models, we doubt the new limited edition WRX S4 tS would be offered outside of Japan. Related Video:

Subaru uses a mime and a toy car to explain why it loves the boxer engine

I will freely admit to struggling with why Subaru continues to stubbornly employ a boxer engine design while so few other automakers do the same. After all, with twice the number of cylinder heads and cams as a traditional inline four-cylinder engine, a boxer four is more complex, more expensive to manufacture and more cumbersome to service with few tangible benefits. Until recently, the company's engines struggled to meet the fuel economy numbers of its competitors while offering no real boon in horsepower or torque. Subaru seems to recognize I'm not the only one scratching my head.
In order to help us non-believers understand what's what, the company has employed a pair of mimes, a toy car and a few clay engines to demonstrate the folly of every other automaker on the planet. Subaru says the boxer offers up a lower center of gravity than either an inline four-cylinder engine or a V6, which I will gladly concede. The company also says the design offers up smoother operation.
I'll offer just two counterpoints here. First, an engine with a low center of gravity is excellent, but when vehicles like the Forester, XV Crosstrek and Outback boast more ground clearance than most mainstream SUVs, that argument flies out the window. Second, anyone who's spent any amount of time behind the wheel of a vehicle equipped with an inline four and then proceeded to move into one propelled by a boxer can tell you the latter has all of the idling manners of a small tractor.

Cosworth announces Power Packages for Subaru BRZ, Scion FR-S with up to 380 hp [w/video]

Cosworth stands on the list of the most famous engine tuners in the world with its DFV engine engine dominating Formula One for a time in the '70s. So when it teases plans to take on the FA20 engine from Subaru and Toyota found in the BRZ, Scion FR-S and Toyota GT86 abroad, our interest is indeed piqued. Cosworth is promising to take the 2.0-liter, four-cylinder boxer engine from its current 200 horsepower all the way to 325 hp and even 380 hp in a future track version through a series of staged Power Packages. At the moment, only the first stage is available that takes the mill to a potent 230 hp.
Cosworth says that its new strategy is to offer its upgrades in kits rather than individually so that it can be sure that everything works and fits when owners receive it. The Stage 1 Power Package emphasizes helping the FA20 breathe better and includes a nearly complete replacement for the stock exhaust system. There is a sports exhaust with four-inch, diagonally cut, polished tips and Y-shaped muffler, an overpipe front pipe with a spherical resonator and a new manifold header that is 22 percent lighter the standard unit. In addition to that, the kit comes with a software reflash, low temperature thermostat, Cosworth badge and plaque.
The stage one kit is available now, and stages two and three go on sale later this summer, according to its website. Autoblog contacted Cosworth for pricing information for the kits. We will update this story, if we hear back. The company also released a video showing off the exhaust upgrades. Scroll down to watch it and read the full release, below.
