The Subaru Impreza 22B STI remains the absolute pinnacle of Japanese automotive engineering from the golden era of rallying. Released in 1998 to celebrate Subaru's 40th anniversary and their third consecutive World Rally Championship manufacturers' title, this two-door widebody icon is much more than a standard Impreza with a body kit. It's a street-legal racing machine built with a bespoke 2.2-liter closed-deck engine, aggressive WRC-derived styling, and mechanical components that collectors chase decades later.
With a notoriously restricted production run—reportedly just 400 units for the Japanese domestic market, alongside a handful of official prototypes and rare export models—the 22B occupies rare air. Understanding why this analog masterpiece commands multi-hundred-thousand-dollar price tags today requires diving past the mythology to examine the engineering, production realities, and ownership nuances.
Engineering the Legend: What Made the 22B Different
Most performance variants of the first-generation GC8 chassis relied on the standard 2.0-liter EJ20 turbo engine. The 22B tore up that playbook by utilizing a bored-out, closed-deck 2.2-liter EJ22 block, heavily influenced by Subaru's rally development programs.
While Japanese manufacturers adhered to a strict "gentlemen's agreement" capping advertised output at 280 PS (276 horsepower), real-world performance punched well above that paper figure. Torque delivery was the defining characteristic: instead of screaming high up the rev range, the 22B produced 363 Nm (265-268 lb-ft) of torque at a remarkably low 3,200 rpm.
- The Engine: An EJ22 closed-deck block paired with cylinder heads borrowed from the STI Version 4, featuring sodium-filled exhaust valves and low-friction molybdenum-coated pistons.
- The Drivetrain: A reinforced 5-speed manual transmission featuring shot-peened gears and a dual-mass ceramic/sintered twin-plate clutch, mated to a Driver Controlled Center Differential (DCCD).
- The Footwork: Bilstein inverted struts paired with Eibach springs, widening the track significantly to match the bulging WRC-inspired steel quarter panels.

Exterior Design and Interior Accents
Park a 22B next to a standard 1998 Impreza WRX STI coupe, and the differences are striking. The widened steel fenders added 80mm to the overall width, mirroring the stance of Colin McRae's WRC rally weapon. Finished exclusively in iconic Sonic Blue Mica and rolling on gold 17-inch BBS forged alloy wheels wrapped in Pirelli rubber, the visual formula defined an entire generation of street tuning.
A vented aluminum bonnet, unique front bumper, and an adjustable rear wing complete the aerodynamic package. Inside, the cabin favors driver engagement over luxury. Blue-grey suede bucket seats, a red-stitched Nardi leather steering wheel, and a serialized brass plaque on the center console remind occupants they're sitting in something extraordinary.
Authenticity Pitfalls: Spotting Real 22Bs vs. Replicas
Because genuine 22Bs command astronomical market values, the enthusiast community is plagued by conversions. Unscrupulous builders often take a standard GC8 coupe, weld aftermarket widebody quarters onto it, and attempt to pass it off as the real deal.
Inspecting a claimed 22B requires verifying specific factory markers:
- Chassis Number: Authentic Japanese-market models carry specific initial VIN sequencing (typically starting with GC8E2SD).
- Engine Stamp: Look for the genuine EJ22 block stamp rather than a modified EJ20.
- Quarter Panel Construction: Real 22Bs feature factory-stamped widebody rear quarters integrated seamlessly into the unibody, whereas cheap replicas often reveal cut seams or bondo filler upon closer inspection.

Frequently Asked Questions
How many Subaru Impreza 22B STIs were actually built?
Official production figures state that 400 units were built for the Japanese market, selling out in less than 48 hours. In addition to those 400, Subaru produced a small handful of prototypes (including serial number 000) and roughly 16 to 25 export units officially sent to the UK and Australia.
Is the 22B engine swap-compatible with a regular WRX?
Technically yes, but it's economically impractical. The EJ22 closed-deck block used in the 22B is distinct from standard production blocks, making genuine replacement parts exceptionally scarce and expensive.
Why is it called the "22B"?
The "22" refers to the 2.2-liter displacement of the upgraded engine. While debate lingers within the enthusiast community regarding the letter "B", it is widely accepted to reference Bilstein suspension or internal Subaru code nomenclature.
Can you legally import a 22B into the United States?
Yes. Because the car was manufactured starting in 1998, it has crossed the 25-year age threshold under federal import laws, allowing enthusiasts to legally bring them into the U.S. under the historic import exemption rules, provided all customs and EPA/DOT documentation is clean.
