If you're rebuilding a Toyota 3S-GE engine for performance, JE Pistons offers a set of four forged pistons designed to handle the demands of high-output applications. These pistons are 86.5mm in bore size and are 1.00mm oversize, meaning they are intended for a cylinder bore that has been machined to accommodate this larger size. With a compression ratio of 9.5:1 and a -15cc inverted dome, they are specifically crafted to optimize performance and durability for your engine build.

JE Pistons uses a proprietary forged side relief (FSR) design, which helps reduce friction and skirt wear while also saving weight. They are forged from 2618 aluminum, a material known for its high tensile strength, making these pistons well-suited for high-demand performance uses. Each piston is designed specifically for the 3S-GE engine to ensure optimized performance and longevity. This kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, all manufactured 100% in the USA.

This set is intended for engines that have been bored out to 86.5mm. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
