What is the dish volume of these pistons and how does it affect compression?

These pistons have a dish volume of -24.00cc. The dish volume, along with your engine's cylinder head volume and gasket thickness, will determine the final compression ratio. A larger dish volume generally lowers the compression ratio.

What material are the wrist pins made from?

The wrist pins included with these pistons are made from tool steel, which offers good durability for performance applications.

Are these pistons suitable for a stock engine rebuild?

These pistons are forged from 2618 alloy and are designed for performance applications, often used in high-compression or boosted engines. While they can be used in a rebuild, they are typically chosen when seeking increased power and durability beyond stock specifications.

About this part

Product Details

If you're rebuilding the top end of your Toyota 5.7L 3UR-FE engine, especially for a performance application, a solid set of pistons is crucial. These Manley Performance pistons are forged from 2618 alloy, a material known for its strength and ability to handle the stresses of increased compression or boost. They are designed with proven cam and barrel skirt profiles, which help them run smoothly against the cylinder walls while still generating power. The wrist pins are made from tool steel for added durability, and the ring lands and grooves are machined to very precise standards to ensure a good seal.

Manley's manufacturing process is quite unique. They use special fixturing that allows them to machine the piston skirt and cut the ring grooves in one operation. This ensures that the ring grooves are perfectly square to the piston skirt, which is important for optimal ring seal and consistent performance. The dish volume on these pistons is -24.00cc, which will affect your final compression ratio depending on your cylinder head volume. These are a popular choice among professional engine builders for their reliability and performance.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. When installing these, remember to follow the manufacturer's recommended clearances and lubrication procedures to ensure they perform as expected and last for the long haul.
