Product Details

The HKS S ZERO 86.5mm piston kit is built for the RB26 engine, taking it out to a 2.8-liter displacement. This kit uses forged aluminum pistons, which are strong enough to handle the increased stress of a larger displacement and higher performance demands. The 86.5mm bore size is a key measurement for achieving the 2.8L capacity when combined with the appropriate crankshaft and connecting rods.

This is a comprehensive kit designed for builders looking to significantly upgrade their RB26 engine. It includes all the necessary pistons, rings, wrist pins, and circlips to rebuild a complete set of cylinders. The forged construction offers improved durability and resistance to detonation compared to cast pistons, making it a solid choice for high-performance applications. HKS is known for its focus on engine tuning and performance parts, and this kit reflects that expertise by providing well-made components for a substantial engine build.

When undertaking an engine build of this magnitude, it's important to ensure all supporting components are up to the task. This includes the crankshaft, connecting rods, camshafts, and the engine management system. Proper balancing of the rotating assembly is also critical for smooth operation and longevity at higher RPMs. This HKS piston kit is a foundational piece for a serious RB26 engine project.
