Wiseco Toyota 2JZGTE 3.0L 86.5mm +.5mm Oversize Bore Asymmetric Skirt Piston Set

These Wiseco pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the extreme pressures found in high-performance 2JZ-GTE engines. They are precisely machined to an 86.5mm bore size, which is a 0.5mm oversize, meaning they are intended for engines that have been bored out to this specific dimension. The asymmetric skirt design is a notable feature, helping to reduce friction and noise during operation while also improving piston-to-wall contact under varying temperatures.

Wiseco has incorporated several features to enhance durability and performance in severe duty applications. This includes precision ring grooves, an anti-detonation groove, and additional features designed to improve ring seal, all contributing to better combustion efficiency and power delivery. The crown of each piston is fully machined, and they feature forced pin oiling to ensure the wrist pins are adequately lubricated, which is vital for longevity under heavy loads. The pistons also come with an ArmorGlide skirt coating, which further reduces friction and resistance to seizure, making them well-suited for demanding race builds.

This set includes six pistons, designed to be a comprehensive solution for rebuilding or upgrading your 2JZ-GTE engine. 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, especially when dealing with oversize pistons and performance engine builds.
