JE Pistons Toyota 3SGE 87mm Bore +1.00mm Oversize 9.5:1 CR -15cc Dome - Single

Forged from 2618 aluminum, these JE Pistons are built for high tensile strength, making them a solid choice for performance builds on your Toyota 3S-GE BEAMS engine. This specific piston is designed for an 87mm bore and is +1.00mm oversize, intended to help restore compression and power in engines that have been bored out. The 9.5:1 compression ratio and -15cc inverted dome are engineered to work with specific cylinder head configurations for optimized combustion. Each piston is made 100% in the USA, reflecting JE Pistons' extensive experience in creating durable and high-performing engine components.

JE Pistons utilizes a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also contributes to saving weight. Depending on the specific application, a skirt coating may be applied to further reduce friction and wear on the piston skirts and cylinder walls, which also helps to quiet down engine noise. An accumulator groove is also included in some applications to help manage combustion gas pressure, reducing ring flutter and improving the piston ring seal for consistent power delivery.

This listing is for a single piston. It includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings. Please note that this part is not CARB approved and cannot be shipped to California.
