JE Pistons Toyota 1FZ-FE 101mm Bore + 1.00 Size 8.5:1 CR Pistons

JE Pistons is known for making well-built forged racing pistons, with over 75 years of experience. They've applied that knowledge to this specific piston set for the Toyota 1FZ-FE engine. If you're rebuilding the top end of your 1FZ-FE and need pistons that can handle serious work, this set is built for that purpose.

These pistons are forged in the USA from 2618 aluminum, which gives them the strong tensile strength needed for high-demand performance applications. They feature JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight with a shorter wrist pin. Depending on the specific application, they may also include an accumulator groove to help reduce combustion gas pressure, improving ring seal and preventing ring flutter. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This set is designed specifically for the 1FZ-FE engine and includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings. They are machined to a 101mm bore size, which is 1.00mm over the stock size, and have a compression ratio of 8.5:1. Remember that these pistons are not CARB approved and cannot be shipped to California.
