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

If you're rebuilding the engine in your Nissan RB25DET Skyline for serious performance, a strong set of pistons is where you start. This Wiseco piston kit is built for those demanding builds where reliability under extreme stress is key. These aren't just replacement parts; they're designed to handle the kind of power and heat that comes with heavy-duty racing applications.

Wiseco forges these pistons from 2618 aluminum right here in the USA, giving them improved tensile strength for better durability. They feature precision ring grooves, anti-detonation grooves, and other features to ensure a solid seal. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and keep things running quieter. The fully machined crown and forced pin oiling are details that show these pistons are made for the long haul in tough conditions.

This kit includes six pistons, each with a 14cc dome and a bore size of 86.25mm, which is .010 inch oversized from the factory specification. Remember, these pistons are not CARB approved and cannot be shipped to California. For a serious engine build, these Wiseco pistons are a well-built choice.
