Wiseco Nissan QR25DE Sentra 2.5L 16V 90.00mm Bore +.040 Oversize -19.5 Dome Dish 8.55 CR Piston Set

Wiseco is well-known for making tough, reliable engine components for demanding applications. This Professional Series piston set is a prime example, built for serious racers and builders who need top performance and durability from their Nissan QR25DE engine. If you're rebuilding the top end of your Sentra 2.5L for heavy or severe duty, these pistons are designed to handle the stress.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for high-performance use. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. You'll also find an ArmorGlide skirt coating that helps reduce friction, resist seizure, and keep operation quieter. The fully machined crown and forced pin oiling further contribute to their ability to withstand severe duty performance builds.

This set includes four pistons, each with a 90.00mm bore and a +.040 inch oversize. They have a -19.5 dome dish, resulting in a compression ratio of 8.55:1. Please note that these pistons are not CARB approved and cannot be shipped to California.
