The RACE SPEC (R in SR3L-i) version of the now world-acclaimed S3L – Street Block has received even more improvements to increase the power and torque over the entire power band and is designed for race fuels only (or E85 if you so choose). One of the first items of change was to strengthen the crank and use a 79mm BILLET crank (that is lighter than stock but far stronger) to handle even more power in cases where a Ken Block wants to do some Gymkhana practicing... 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.

When Ken asked "Is it ok for me to bounce it off the rev limiter?" we said YES it was, even though the rev limit for this package was set to 8500 RPM's.

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 superior products within reach of all our clients at a fraction of the cost of the competition.

The Crawford Performance long block has been designed to handle even the worse of Ken Block and it has proven itself in Ken's Gymkhana 1 vehicle over 5 million times on YouTube alone. This is only the first installment of Race Spec's engines being offered by Crawford Performance. Just wait till Gymkhana 2 is released early this summer...
