Japanese Subaru fans are getting quite a treat in time for Halloween. The brand is unveiling the WRX STIS207 edition at the Tokyo Motor Show. Unfortunately for brand devotees elsewhere, the market-exclusive, high-performance model is limited to just 400 units there.

For such a small run of cars, the folks at Subaru Tecnica International are adding quite a bit to take the STI’s performance to new heights. Among the upgrades, the 2.0-liter, turbocharged boxer now makes 323 horsepower and318 pound-feet of torque – a healthy jump compared to 305 hp and 290 lb-ft from the 2.5-liter engine in the US-market version. Beyond the extra power, the sedan also wears a load of parts to improve chassis stiffness and a DampMatic II adjustable front suspension from Bilstein. Styling sees some slight tweaks with a red-outlined mesh grille, chin spoiler, 19-inch BBS wheels, and a redesigned rear bumper. Inside, the front passengers are held tight in leather-trimmed Recaro seats.

If the 400 units aren’t exclusive enough, Subaru technically breaks the S207 into three special editions. A planned run of 200 units will feature the NBR Challenge Package that’s inspired by the company’s class victory in the 2015 Nürburgring 24 Hours. It adds a carbon fiber rear spoiler, black wheels, red seatbelts, and an Ultrasuede-covered steering wheel. A hundred of those are the NBR Challenge Package Yellow Edition that come exclusively in Sunrise Yellow with black-painted door mirrors and side sills. Depending on the version, prices before Japan’s consumption tax would be between $46,050 and $48,950 at current exchange rates.
