About this part

Product Details

HKS is well-known for its high-performance engine components, particularly for Japanese performance vehicles. This BCD Full Piston Kit is a prime example, designed specifically for the RB26 engine to bring it up to a 2.8L displacement with an 86.5mm bore size. If you're building a serious performance RB26, this kit is a foundational piece for handling increased power and stress.

This kit includes forged pistons, which are significantly stronger and more durable than cast pistons. This strength is crucial for engines that are modified to produce more horsepower, as forged pistons can better withstand the higher combustion pressures and temperatures. The 86.5mm bore size is a common upgrade for the RB26, allowing for increased displacement and improved volumetric efficiency. The BCD designation refers to a specific design feature from HKS aimed at optimizing combustion chamber performance, which can lead to more efficient power delivery and better response.

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, and the engine block itself, which will need to be machined to accommodate the larger bore. Proper balancing of the rotating assembly is also critical for engine longevity and smooth operation at higher RPMs. This HKS piston kit is intended for serious engine builders who understand the requirements of a high-performance build.
