What is the compression height and pin diameter for these pistons?

These Wiseco pistons have a compression height of 33.94 mm and a wrist pin diameter of 0.827 inches. These measurements are critical for proper engine assembly and valve-to-piston clearance.

Are these pistons suitable for a daily driver or only for racing?

While built with racing features like improved tensile strength and severe duty design, the ArmorGlide skirt coating also helps reduce friction and noise. They are intended for serious builders and racers who push their engines hard.

What does the 'Not CARB approved' note mean?

This means the pistons do not meet California Air Resources Board (CARB) emissions standards. As a result, they cannot be legally shipped to California for use on vehicles registered in that state.

Product Details

If you're rebuilding the engine in your 1995-1998 Nissan 240SX for serious performance, this Wiseco forged piston kit is built to handle the demands. These pistons are designed for heavy to severe duty race applications, offering a significant upgrade over stock components. They feature a dished crown to achieve a 10.5:1 compression ratio with a 90.0mm bore, making them a solid choice for builders looking to extract more power from their KA24DE engine.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, and then machines them right here in the USA. You'll find precision ring grooves, anti-detonation grooves, and features designed to improve ring seal, all contributing to better performance and durability. The piston crowns are fully machined, and they include forced pin oiling to ensure the wrist pins stay well-lubricated under high stress. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, keeping your engine running smoothly.

This set includes four pistons, each with a 33.94 mm compression height and a 0.827 inch pin diameter, ready to be installed in your KA24DE block. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For a build that needs to withstand serious abuse, these Wiseco pistons are a well-built option.
