A series of low-volume versions with even greater power and grip were built by Subaru's in-house modifier, Subaru Tecnica International (STi). STi versions of the Impreza, which produced 280 PS (206 kW) from new, are often raced, largely unmodified, in the Group N class in various rally championships to great success. Introduced in 1994, the STi has proven to be a very popular high-performance machine in the Japanese domestic market. Introduced to the United States in 2004, the US model STi features the larger displacement 2.5L (EJ257) that features AVCS.
The Brian Crower Stage 2 Race Specification Cams are a longer duration profile, added rpm potential. Intended for fully built engine. Tuning and ECU mods recommended. Requires kit BC0600.
