Subaru Model: MY98 Subaru Impreza 22B STi – #300/400
ISDC Forum Name: naill1

Original Model Information:


In 1998, Subaru of Japan produced a widebody, 2-door, Impreza called the 22B STi. The 22B had the EJ22 engine as opposed to the regular EJ20 engine. This means the displacement was increased from 1994 cc to 2212cc. The block was a closed-deck borrowed from the Legacy’s EJ22. The heads (valves, valvetrain and such) were lifted from the STi Version 4 engine. It produce 280 PS (206 kW) and 363 N/m (37.0 kgf/m) of torque at a lower engine speed of 3200 rpm. The redline was lowered from 8000 rpm to 7000 rpm.

The 22B was used to commemorate the 3rd consecutive manufacturer’s title for Subaru in the FIA World Rally Championship. This car was given a unique color of blue and had fender flared widebody taken from the Peter Stevens designed WRC car. It sported a Bilstein suspension, a triple-plate clutch, cryo-treated gears, a unique spoiler, a unique bumper and custom BBS gold wheels.

The origin of the name 22B has often been debated. Many assume 22 referred to the 2.2 liter displacement and the B was for the Bilstein suspension. This would correlate with the idea that Subaru sells a Legacy Spec B, where the B represents the Bilstein suspension. Others believe that 22B was meant to represent the much recognized 555 decal on the WRC car as 22B is a hexadecimal representation of the decimal number, 555.

It is interesting to note that the 22B STi that is suppose to be #13 was never given the plaque. Subaru of America imported #13 to be used as a press car.

2.2 litre engine restricted to 280 PS (276 bhp) for the Japanese domestic market
