What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its strength and performance characteristics, making it suitable for high-output engine builds.

What is the compression ratio of these pistons?

This specific piston set features a 9.0:1 compression ratio. This is a common target for many performance RB26DETT builds, offering a good balance between power and pump gas compatibility.

Are these pistons compatible with all RB26DETT engines?

These pistons are designed for the Nissan RB26DETT engine with an 86.25mm bore. It's crucial to ensure this bore size matches your engine's requirements, as it is an overbore from the stock dimension. They are not CARB approved and cannot be shipped to California.

About this part

Product Details

If you're building a high-performance Nissan RB26DETT engine, this set of Manley Performance pistons is a solid choice. These are forged pistons designed for the RB26DETT engine, with a bore size of 86.25mm and a compression ratio of 9.0:1. They are built using Manley's signature "Platinum Series" construction, which means they start with domestic 2618 alloy forgings. This material is known for its strength, making it ideal for demanding engine builds where reliability and performance are key.

Manley puts a lot of thought into the details that make these pistons work well. They use proven cam and barrel skirt profiles, which help the piston move smoothly in the cylinder while still creating good sealing. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings and making more power. You'll also find that these pistons come standard with premium Chrome Moly wrist pins, and for some part numbers, Manley offers upgrades to even stronger alloys like 9310 or Turbo Tuff/DLC for extra durability. The unique machining process Manley uses ensures the ring grooves are perfectly square to the piston skirt, contributing to overall engine health and performance.

This set is not CARB approved and cannot be shipped to California. It's important to note that these pistons are intended for performance engine builds and are not a direct replacement for stock components without other supporting modifications. Always consult with your engine builder or refer to Manley's installation guidelines for proper fitment and assembly procedures.
