What is the significance of the +.25mm oversize bore dimension?

The +.25mm oversize means these pistons are intended for an engine block where the cylinders have been bored out by 0.25mm from their original factory size. This is often done to clean up cylinder walls or to achieve a specific final bore size for performance builds.

What is included with this piston set?

This set includes the Manley Turbo Tuff pistons and the necessary piston rings. It is designed to be a complete piston and ring package for your engine build.

Are these pistons suitable for naturally aspirated engines?

While these pistons are designed with a -1cc dome and 10:1 compression ratio specifically for turbo applications, they are built with strong 2618 alloy forgings. However, for optimal performance and tuning, they are best utilized in a turbocharged setup as intended.

About this part

Product Details

If you're building a high-performance Toyota 2JZGTE engine, a solid set of pistons is crucial. This set from Manley Performance is designed for the 2JZGTE engine, featuring an 86.25mm bore and a +.25mm oversize dimension, meaning they are meant for a cylinder bore that's been slightly enlarged from stock. The -1cc dome and 10:1 compression ratio are specifically tuned for turbo applications, aiming for a balance of power and responsiveness.

Manley uses their signature 2618 alloy forgings for these pistons, which are known for being strong and reliable under demanding conditions. They also come with premium chrome moly wrist pins, and the skirt profiles are carefully shaped to reduce friction and wear on the cylinder walls while still helping to generate power. The ring lands and grooves are machined to very tight tolerances, which is important for getting a good seal with the piston rings, ultimately leading to better engine performance.

This set includes the pistons and rings, ready for installation. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a serious 2JZGTE build, these Manley Turbo Tuff pistons offer a well-built foundation.
