Wiseco Nissan FJ20 90.0mm Bore .040 Oversized -16.7cc Dome Dish Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable engine components, especially for performance applications. This Professional Series forged piston kit for the Nissan FJ20 engine is a prime example of their commitment to serious builders. These aren't your average pistons; they're designed from the ground up for heavy to severe duty race builds where every component needs to perform under extreme stress.

Crafted in the USA from 2618 aluminum, these pistons offer improved tensile strength, which is crucial when you're pushing an engine hard. They feature precision ring grooves, an anti-detonation groove, and other features to enhance ring seal, ensuring efficient combustion and durability. The fully machined crown and forced pin oiling further contribute to their robust design. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, leading to quieter operation and longer life even in demanding conditions.

This kit includes four pistons, each measuring 90.00mm in bore diameter and is .040 inches oversized. The dish volume is -16.7cc, and the compression height is 32.18mm, with a standard 0.866 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. They are intended for competition use and are built to withstand the rigors of racing.
