The race-ready version of the now world-acclaimed S3L – Street Block has received more improvements to allow for additional power and torque over the entire power band. One of the first items of change was to strengthen the long rods to handle even more power in cases where a GT35R turbocharger is just not big enough. Other improvements include improving the efficiency and responsiveness of the valves and springs in order to run higher RPMs at higher power levels without sacrificing low end torque.

These professional techniques have put Crawford Performance at the forefront of Subaru performance. With over 30 years of professional racing experience, CP has brought the racing world’s goods within reach of all our clients at a fraction of the cost.

This block has become the ultimate sleeper, created to win at the track under any condition while improving the overall powerband of the S3L – Street package. The S3L – Race was purpose-built for endurance at the track and daily driving needs.

The Street-Prepped heads have been daily driven to and from the race track and then proven on the race track for ultimate performance. Designed to give you the potential from various short block options without sacrificing driveability around town and in traffic.
