Wiseco Nissan FJ20 89.50mm Bore 32.18mm CH -16.70cc Professional Piston Kit

Wiseco is well-known for making strong internal engine components, especially pistons, for demanding applications. This Professional Series piston kit for the Nissan FJ20 engine is a prime example of their commitment to performance and durability. These aren't your average pistons; they're built from 2618 aluminum, which offers improved tensile strength over other aluminum alloys, making them well-suited for heavy to severe duty race builds where reliability is key.

You'll find a lot of attention to detail here. The ring grooves are precisely machined, and there are features like anti-detonation grooves and additional ring seal improvements to help keep everything running smoothly under pressure. The crown is also fully machined, and they've included forced pin oiling to ensure the wrist pin stays well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, which is a big plus for longevity in a high-performance engine.

This kit is designed for builders who are serious about getting the most out of their FJ20. It includes everything you need for a set of four pistons, with a specific 89.50mm bore size and a 32.18mm compression height. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, this Wiseco kit offers a solid foundation.
