EJ257 BILLET FSR
The first billet racing pistons made by JE Pistons for the Subaru EJ257 engine! 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 designed for high horsepower road and drag engines. The pistons feature internal and external bracing for improved durability and strength. A unique "donut dish" crown and application-specific undercrown profile properly redistributes heat and reduces stress concentrations experience 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!
They are 100% CNC machined from high quality 2618-T6 aluminium alloy and weight just 392 grams. The pistons are designed for applications of up to 1200hp thanks to the Internal and external strut braces.
9310 steel gudgeon pins are included with DLC (Diamond Like Coating) upgrade available. JE pro seal piston rings are also included as are the Tru Arc circlip locks.
