What does '+1.0mm oversized bore' mean for my engine rebuild?

This means the piston's diameter is 1.0 millimeter larger than the original factory specification. This is commonly used when an engine's cylinders have been worn beyond their original size or when a builder wants to achieve a slightly larger displacement for increased power.

What is the advantage of 2618 alloy forgings?

2618 alloy is chosen for its excellent strength and toughness, especially at higher temperatures. This makes it a popular choice for performance pistons that need to withstand the stresses of high-horsepower, turbocharged engines.

Are these pistons compatible with all 2JZGTE engines?

These pistons are designed for the 2JZGTE engine, but the +1.0mm oversized bore means your engine's cylinders must be machined to this specific size to ensure a proper fit. Always consult with your engine builder or machinist to confirm fitment and necessary machining.

About this part

Product Details

Manley uses domestic 2618 alloy forgings for these pistons, a strong material chosen for its ability to handle the demands of high-performance engines like the Toyota Supra's 2JZGTE. These are a +1.0mm oversized set, meaning they are 1 millimeter larger in bore diameter than the stock pistons, which is useful when rebuilding an engine with some wear or when you need to achieve a specific displacement. The 9:1 compression dish helps manage combustion pressure and heat in turbocharged applications.

The design includes proven cam and barrel skirt profiles that help the piston move smoothly in the cylinder, reducing wear on the cylinder walls while still allowing the engine to make good power. Manley also pays close attention to the ring lands and grooves, ensuring a tight seal with the piston rings. This precise fit is crucial for proper compression and oil control, ultimately contributing to more power and better engine longevity. Each set comes with tool steel wrist pins for added durability.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are intended for performance engine builds where precise fitment and robust materials are key.
