Origins & Early Years

The WRC Ambition

Subaru’s rally ambitions began in 1988 when Fuji Heavy Industries (FHI) created Subaru Tecnica International (STI) as its motorsport division. The goal was to develop and compete in the FIA World Rally Championship, following the homologation rules that required production-based cars.

At the time, Subaru had the Legacy sedan competing in Group A, but it was too large and heavy to be truly competitive. The company needed a smaller, more agile platform that could better handle the tight forest stages of the WRC.

The solution was the Impreza, introduced in November 1992. This compact car provided the perfect foundation for a rally weapon. Its lighter weight and more compact dimensions made it ideal for the demanding stages of the World Rally Championship.

The WRX version, launched in Japan in 1992, was the first step. It featured a turbocharged 2.0-liter boxer engine producing 237 horsepower, already making it a performance contender. But the STI version would take this formula to an entirely new level.

Boxer Engine Foundation

The heart of the WRX STI was its boxer engine, a Subaru signature since the 1960s. The horizontally-opposed cylinder layout provided a low center of gravity, reducing body roll and improving handling balance.

The initial STI engine was the EJ20, a 2.0-liter turbocharged boxer with DOHC, 16 valves, and advanced fuel injection. It produced 250 horsepower in early versions, with later evolutions reaching 300+ horsepower.

What made the boxer engine special for rallying was its compact size and smooth power delivery. The low mounting position improved weight distribution, while the inherent balance reduced vibration and allowed higher rev limits.

The turbocharger provided the boost necessary for competitive power levels. The IHI turbo units used in early STIs were reliable and responsive, providing strong low-end torque while maintaining high-rpm power.

Symmetrical All-Wheel Drive

Subaru’s symmetrical all-wheel-drive system was what truly set the WRX STI apart. Unlike front-biased systems from competitors, Subaru’s layout was balanced and centered, with equal-length driveshafts to front and rear.

This system provided exceptional traction on all surfaces. On loose gravel, snow, or tarmac, the STI could put power down effectively where competitors struggled with wheelspin.

The center differential used a viscous coupling that could vary torque distribution based on traction needs. In normal conditions, power split was 50/50 front to rear, but it could send up to 80% to either axle when slip was detected.

This all-wheel-drive advantage was immediately apparent in rally competition. While front-wheel-drive competitors struggled for traction, the Subarus could launch harder and maintain speed through corners that would leave others spinning.

Generational Breakdown

The Subaru WRX STI has evolved through six generations over 33 years, each building on the rally-bred formula while adapting to changing regulations and market demands.

Generation 1: GC8 (1992-2000)

The first-generation STI was built on the Impreza GC8 chassis and represented the purest expression of Subaru’s rally philosophy. These cars were essentially road-legal rally cars, with minimal concessions to comfort.

The original STI Version I produced 250 horsepower from its 2.0-liter EJ20 engine. It featured a close-ratio 5-speed manual transmission, upgraded brakes, and distinctive gold wheels that became a signature STI feature.

Each subsequent version brought improvements. Version II (1994) increased power to 275 hp. Version III (1995) added a driver-controlled center differential. Version IV (1996) introduced VVT and increased power to 280 hp.

The 1998 22B STI was the ultimate expression of this generation. Built to commemorate Subaru’s 40th anniversary and third consecutive WRC title, it featured a 2.2-liter engine producing 280 hp, wide-body styling, and extreme rarity—only 400 were built for Japan and sold out within days.

Generation 2: GD/GG (2000-2007)

The second-generation “blobeye” STI arrived in 2000 with a completely revised design. The engine grew to 2.5 liters for most markets, producing 300 horsepower in the EJ257 version.

This generation saw the first official US-market STI in 2004, creating enormous excitement among American enthusiasts. The US model used the 2.5-liter engine and featured larger brakes and wheels than the Japanese version.

The EJ20, used in Japanese and European markets, featured DOHC, 16 valves, and variable valve timing. It produced up to 320 horsepower in special editions while maintaining reliability.

The EJ257, used in US-market STIs, displaced 2.5 liters and produced 300-310 horsepower in standard form. Its larger displacement improved low-end torque, making the car more drivable in daily conditions.

Both engines used IHI turbochargers, with the VF39 being the most common in US models. These turbos provided quick spool-up and strong mid-range power, essential for rally stage performance.

Weak points included head gaskets in early EJ25 engines and connecting rod bearings in high-mileage examples. However, the aftermarket developed robust solutions, and properly maintained engines could exceed 200,000 miles.

All-Wheel-Drive System

Subaru’s symmetrical all-wheel-drive system was the STI’s defining technology. Unlike competitors who adapted front-wheel-drive platforms, Subaru designed the STI around a longitudinal layout with equal-length driveshafts.

The DCCD (Driver Controlled Center Differential) system allowed manual adjustment of torque split between front and rear axles. This was invaluable in rally conditions, where drivers could dial in more rear bias for loose surfaces.

The front and rear limited-slip differentials worked seamlessly with the center differential. The Suretrac LSD in front and Torsen or mechanical LSD in the rear ensured power was delivered to the wheels with grip.

This mechanical system provided immediate response without the delay of electronic systems. Drivers could feel the system working through the steering wheel and pedals, creating a connected driving experience.

Transmission and Drivetrain

The 6-speed manual transmission in the STI was a robust unit designed to handle the engine’s torque. It featured close ratios for acceleration and a direct, mechanical feel that enthusiasts prized.
