JE Pistons is proud to release the first billet racing pistons for Subaru EJ257 engines! Originally created for the Crawford Performance Unlimited AWD Time Attack Subaru and Ken Block's Gymkhana racecar, these pistons are now available to the public. The new pistons are 100% CNC machined from high quality 2618-T6 wrought aluminum bar stock and are specifically designed for high horsepower road and drag race engines. The pistons feature internal and external bracing for improved durability and strength. A unique "donut dish" crown and application-specific under crown profile properly redistributes heat and reduces stress concentrations experienced in high horsepower Subaru engines. Unlike forged pistons, the billet pistons are machined on every surface allowing for all unnecessary weight to be removed during manufacturing. The result of this new process is a weight reduction of up to 32 grams compared to other piston designs! High quality 9310 steel wrist pins and JE Pro Seal Rings are included. For severe racing applications, upgraded Diamond Like Carbon (DLC) coated wrist pins are available. 

  • 8.8:1 Compression Ratio
  • 99.5mm Piston Size
