Wiseco Toyota 2JZ -16cc Dish 86.25mm Piston Set Shelf Stock

This is a set of Wiseco forged pistons specifically made for the Toyota 2JZ engine. These pistons feature an 86.25mm bore size and a -16cc dish, which is a common configuration for naturally aspirated or mild forced induction builds where you want to control compression ratio. Wiseco is well-known for making strong internal engine components, and these pistons are built to handle the demands of a performance 2JZ build.

Forged pistons like these are a significant upgrade over cast pistons. They start as a solid block of aluminum that's heated and hammered into shape, creating a much denser and stronger grain structure. This makes them far more resistant to detonation, heat, and the stresses of high cylinder pressures that you'll encounter in a performance engine. The -16cc dish is designed to work with specific head volumes and deck heights to achieve a target compression ratio, often around 8.5:1 to 9.5:1 depending on the rest of your engine combination. This range is ideal for many street/strip applications using turbochargers or superchargers.

This set includes all the pistons you'll need for a 6-cylinder engine, and they are designed as a shelf-stock part, meaning they are readily available. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a successful build, ensure you pair these pistons with appropriate connecting rods, rings, and bearings. Always consult your engine builder or a trusted professional for specific recommendations tailored to your build goals.
