Subaru readying special-edition BRZ

Another week coming to a close brings another rumor of a potential hotted-up version of the Subaru everyone wants to turbocharge, the BRZ.
A fresh rumor out of the Car and Driver offices makes the claim that a new, special-edition BRZ model will be offered up within the next few months. Word is that the new model will not get similar upgrades to the recent BRZ tS (seen above) for the Japanese market, meaning we're likely in for a cosmetic update instead of a functional one.
The looks of the tS could still be in the cards, however, meaning swapped-out lip spoiler, wheels and even STI badging might be on the way.

Is the Subaru BRZ STI being teased really only a tS version?

Teaser images of a purported Subaru BRZ STI were uncovered last night and sent the internet into a collective state of hysterics. That's not hugely surprising, though, considering the reverence that the BRZ, along with its fraternal twins, the Scion FR-S and Toyota GT86, have garnered from the automotive media. The sole sticking point, really, has been its mere 200 horsepower. People have been chomping at the bit over a higher output version of the sublime rear driver.
Those same people may be in for a disappointment, though. See, the BRZ STI that was teased last night might not be a real STI. Instead, it's looking like it might be a BRZ tS. According to 7Tune.com, the timing of the photos posted on Subaru's website lined up with Subaru's 86 Festival at Fuji Speedway, where the Subaru BRZ tS debuted. Despite wearing STI badges, the tS isn't the full-tilt STI model we've been hoping for. Instead, you can think of the relationship between tS models and STI models as sort of like the difference between a BMW 3 Series M Sport and a BMW M3.
Certainly, the speccing of the tS supports that idea. The engine of the BRZ remains untouched in both tS models, which is one of the primary things we expect a full-bore STI to address. A number of interior and exterior styling items have been added, along with Bilstein suspension pieces and six-pot Brembo brakes. The tS sports two different trim levels, with the higher end using Recaro seats, black alloy wheels, and a carbon-fiber rear spoiler. The base tS features silver wheels, standard seats, and all the same suspension and brake upgrades. Adding fuel to the fire that these are not the true STI models is the limited production run - Subaru will only build 750 tS cars.

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.
