Wiseco Nissan RB2DET Skyline 2.5L 24V 86.25mm Bore .010 Oversized 14cc Dome Piston Shelf Stock Ki

Forged from 2618 aluminum, these Wiseco pistons are built with improved tensile strength, making them a solid choice for serious engine builders tackling heavy to severe duty race applications. The 86.25mm bore size is .010 inch oversized from stock, designed to work with a specific bore size in your RB25DET engine. The 14cc dome volume is a key design element that influences your engine's compression ratio, so it's important to consider this when planning your build.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and other features that help improve ring seal. They also come with an ArmorGlide skirt coating, which is designed to reduce friction, resist seizure, and help quiet down operation. The crown is fully machined, and the pistons feature forced pin oiling to ensure proper lubrication for the wrist pin.

This set includes six pistons, along with premium rings, ready for installation in your Nissan RB25DET engine. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
