Wiseco Nissan KA24 Dished 9:1 CR 90MM Piston Shelf Stock Kit

If you're rebuilding the engine in your 1995-1998 Nissan 240SX for serious performance, a solid set of pistons is where you start. These Wiseco Professional Series pistons are built for demanding applications where reliability and strength are paramount. They feature a dished crown design to achieve a 9:1 compression ratio, which is a popular choice for boosted or high-performance naturally aspirated KA24 engines, offering a good balance between power and drivability.

Wiseco forges these pistons from 2618 aluminum right here in the USA, giving them improved tensile strength for handling the stresses of performance driving. You'll find precision ring grooves, anti-detonation features, and enhanced ring sealing to ensure a tight combustion chamber. The pistons also come with an ArmorGlide skirt coating that helps reduce friction and noise while resisting seizure, and the crown is fully machined for a clean, consistent surface. Plus, they include forced pin oiling to keep the wrist pins well-lubricated under high loads.

This kit includes everything you need for a set of four cylinders, with a 90.00 mm bore and a 33.94 mm compression height. Remember, these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
