Brian Crower BC0622 Stage 3 Street/Race Spec Camshafts for Subaru STi / EJ257

If your looking for the Brian Crower Spring and Retainer kit needed for use with these cams, use kit # BC-0600

BC uses small diameter grinding wheels during the finishing phase when applicable to generate a more aggressive ramp rate for a faster cylinder fill rate. More air + more fuel = more power. Although it takes longer to grind the cams, research and development has proven that the inverted radius created by the small grinding wheel on the opening side delivers more horsepower on radius and roller rocker applications than the conventional, large diameter grinding wheels.

All BC cams are checked on a high speed, sub-micron accuracy measuring gauge. The Adcole Camshaft Measuring System uses individual measuring heads for each cam journal and cam lobe, with .01 micron resolution, taking one datum point each 1/10th of a degree or 3,600 data points per revolution. Measuring camshafts for rise error and chattermark detection, the model at Brian Crower can measure 200 parts per hour.

Brian Crower WRX / STi Street/Race Specification Cams

Longer duration profile, which yeilds a much higer added rpm potential. Intended for a fully built engine either maximizing RPM potential or greater than stock stroked motors. Tuning and ECU mods recommended. Use of these cams requires Brian Crower Spring and Retainer kit # BC-0600.

Designed with a Bucket Diameter: 1.220"

The above cams work with AVCS.

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.
