What is the compression ratio with these pistons?

These pistons feature a dish design that results in a compression ratio of 8.5:1. This is often chosen for forced induction applications or when a specific tuning goal requires a lower compression.

What material are the wrist pins made of?

This set includes premium Chrome Moly wrist pins, which are known for their durability. Manley also offers upgrades to higher-end alloys on select part numbers.

Are these pistons suitable for a turbo or supercharged engine?

Yes, the 8.5:1 compression ratio and the strong 2618 alloy construction make these pistons well-suited for boosted applications. The dish design helps to lower the static compression, which is beneficial for forced induction.

About this part

Product Details

Manley Performance is well-known for building serious engine components, and their forged pistons are a popular choice for anyone looking to push their engine's limits. This specific set is designed for 2003-2009 Nissan 350Z, 2003-2007 Altima, Maxima, and other compatible vehicles like the Infiniti G35 and FX35. If you're rebuilding or modifying your VQ35 engine, these pistons are a solid foundation for improved performance and reliability.

These pistons are forged from domestic 2618 alloy, which is chosen for its strength and ability to handle the stresses of a high-performance engine. They feature proven cam and barrel skirt profiles that help reduce friction and wear on the cylinder walls, while also contributing to power gains. The ring lands and grooves are machined to strict standards to ensure a good seal, which is crucial for making consistent power. Manley's unique manufacturing process allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other for optimal performance.

This set includes tool steel wrist pins for added durability, and the dish design results in an 8.5:1 compression ratio, making it suitable for boosted applications or engines that require a lower compression for specific tuning goals. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct piston rings and potentially new connecting rod bearings to go along with them.
