Wiseco Nissan QR25DE Sentra 2.5L 16V 89.50mm Bore +.020 Oversize -1.8 Dome Dish 10.46 CR Piston Set

If you're rebuilding the engine in your Nissan Sentra with the QR25DE 2.5L engine for serious performance, a well-built set of forged pistons is a critical component. These Wiseco pistons are made from 2618 aluminum, which offers improved tensile strength compared to cast aluminum, making them suitable for heavy to severe duty race applications where reliability under extreme stress is paramount.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features designed to improve ring seal. The crown is fully machined for a clean combustion chamber, and they include forced pin oiling to ensure the wrist pins stay well-lubricated. The pistons also feature an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. This set is +.020 oversize, meaning the bore diameter is 89.50mm, which is 0.020 inches larger than the stock bore size.

This set is designed for builders who are pushing their engines hard. 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.
