Short Block: CP S3L-H WRX (2002 - 2014)
All components engineered & manufactured by Crawford Performance have been tested for ultimate performance and maximum dependability on and off the race track. Our rigorous testing and numerous accolades assure our clientele that we at Crawford Performance demand the best of ourselves and the products we create. Our clients deserve nothing less.
Where as the S3L-X is more of a brute, the Crawford S3L-H can be described as the more refined and happy little brother. It is designed around a brand new EJ257 semi closed deck block that incorporates a counterweighted 79mm forged STI crankshaft, longer Crawford Billet H-beam rods and Crawford’s 99.5mm offset forged pistons. We use the High performance STI main and rod bearings in this block along with the STI piston rings. These Genuine STI components allow for maximum safety and reliability, because why fix what's not broken? No cheap knock off parts here. To keep with our high quality standards, we use Crawford offset wristpins to decrease the piston noise associated with forged pistons. Like its big brother, the Crawford Billet H-beam rods serve two purposes; 1) to increase the rod ratio which allows for smoother and efficient power delivery and 2) most importantly… the H-beam rods are engineered to be 90grams lighter per rod than the X-Beam rods. Light rods equate to a lighter rotating assembly, which means, a happier and faster revving motor. The S3L-H is best suited for a pump gas motor.
There are too many factors in a performance build to put an exact number to this motors horsepower and torque potential, so we give each of our motors a "Rated Output" number. We have seen the S2 withstand up to 550bhp. But no worries, if this isn't enough to satisfy that itch for more power, than check out our other Short Blocks built to last with numbers as high as 800bhp.
