Crawford Built Short Block STI EJ257 S3L-X | S0114

All components engineered and manufactured by Crawford Performance have been tested for ultimate performance and maximum dependability on and off the race track. For over 2 decades they have tested all combinations of upgrades for the turbo-charged EJ20, EJ25, and more recently the new FA20 Subaru engines. Crawford has pushed these engines to there breaking points to determine which components fail at what level. From that research they have come up with forged internals to keep your engine strong enough to withstand your desired power level.
