Wiseco 95-98 Nissan 240SX KA24 4V Dished 9:1 CR 90.50MM Piston Kit *Special Order*

If you're rebuilding the engine in your 1995-1998 Nissan 240SX with the KA24DE engine, this Wiseco forged piston kit is built for serious performance. These aren't your average pistons; they're designed for heavy-duty race builds where durability and power are critical. The kit includes four pistons, each measuring 90.50mm in bore diameter, with a dished crown that results in a 9:1 compression ratio. This specific compression ratio is a well-known sweet spot for many performance applications, offering a good balance for boosted or naturally aspirated setups.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, which is essential for handling the extreme pressures and heat generated in high-performance engines. They feature precision ring grooves for a solid seal, anti-detonation grooves to prevent pre-ignition, and forced pin oiling to keep the wrist pins properly lubricated. The piston crowns are fully machined for accuracy, and the skirts are coated with ArmorGlide, a special coating that reduces friction and resistance to seizure, while also contributing to quieter operation. This attention to detail means these pistons are built to withstand severe duty applications.

This is a special order item, so please plan accordingly. It's important to note that this kit is not CARB approved and cannot be shipped to California. For a successful rebuild, ensure you have all necessary supporting components and refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
