What is the primary benefit of the 2.8L displacement increase?

The 2.8-liter displacement increase allows the engine to displace more air and fuel with each combustion cycle. This generally leads to improved torque and horsepower potential, especially when combined with other performance modifications.

What materials are the pistons made from?

The pistons in this kit are forged from a high-strength aluminum alloy. This material choice offers a strong yet lightweight option, crucial for high-performance engine components that must withstand significant stress.

What else might I need for this engine build?

For a complete engine build, you will typically need to consider new piston rings, connecting rod bearings, main bearings, gaskets, seals, and potentially an upgraded oil pump and oil cooler. It is always best to consult with your engine builder for a comprehensive parts list.

Product Details

Forged from high-strength aluminum alloy, this HKS full piston kit is built to handle the demands of a performance RB26DETT engine. This kit specifically enables a 2.8-liter displacement increase, often referred to as a STEP2 build, which is a significant step up from the factory 2.6-liter configuration. The advanced forging process creates a piston that is both lightweight and incredibly durable, crucial for maintaining reliability under higher boost pressures and increased combustion forces common in modified engines.

Each piston in this kit is precision-machined to exact specifications, ensuring a perfect fit within the cylinder bore and proper sealing with the piston rings. The kit includes all necessary components for a complete engine build, allowing for a comprehensive upgrade to your RB26DETT's internal rotating assembly. This attention to detail in manufacturing helps to minimize friction and improve overall engine efficiency, translating to better power delivery and a more responsive feel when you're on the throttle.

When undertaking a build of this magnitude, it's important to ensure all supporting components are up to the task. This HKS kit is designed for enthusiasts looking to push the limits of their RB26DETT engine, whether for track use or high-performance street applications. Please note that this kit is not CARB approved and cannot be shipped to California. Always consult with a qualified mechanic or engine builder to ensure proper installation and compatibility with your specific build goals.
