What is the benefit of the nickel plating on these pistons?

The nickel plating on the piston skirts is designed to reduce friction and wear. This is particularly beneficial during engine break-in and under high-load conditions, contributing to improved durability and a longer lifespan for the engine.

What other parts are typically needed when installing this piston kit?

This kit includes the pistons themselves. You will also need to source matching piston rings, wrist pins, and connecting rods for a complete engine build. Always consult the manufacturer's instructions for a full list of required components.

Does this piston kit come with piston rings and wrist pins?

No, this HKS Ni Piston Kit includes the forged pistons only. You will need to purchase compatible piston rings and wrist pins separately to complete the installation.

Product Details

If you're rebuilding the heart of your RB26 engine for serious performance, a strong set of pistons is crucial. This HKS Ni Piston Kit is built for those pushing their engines hard, offering a well-built foundation for boosted applications. The RB26 is a legendary engine, and using components designed to handle its potential is key to a reliable build.

These pistons are forged from a high-strength aluminum alloy, specifically chosen for its ability to withstand the extreme pressures and temperatures found in a high-performance, turbocharged engine. The 'Ni' in the name refers to the nickel plating on the piston skirts, a feature that helps reduce friction and wear, especially during the critical break-in period and under high-load conditions. This plating contributes to improved durability and a longer lifespan for your engine build. The kit includes pistons sized for an 86mm bore, which is a common size for many RB26 builds, and the 'S2' designation indicates a specific compression ratio and dish volume tailored for certain performance goals. You'll want to ensure this specific compression ratio aligns with your camshafts and intended boost levels for optimal performance.

When undertaking an engine rebuild of this caliber, it's important to have all the necessary supporting components. This kit includes the pistons themselves, but you'll also need to source matching piston rings, wrist pins, and connecting rods. Always refer to the manufacturer's installation instructions for precise details on assembly, ring gap settings, and break-in procedures to ensure the longevity and performance of your new engine build.
