Wiseco Mits Turbo DISH -22cc 1.378 X 87MM Piston Shelf Stock Kit

If you're rebuilding the engine in your 1989-1991 Hyundai Sonata for serious performance, especially with a Mitsubishi turbo setup, these Wiseco forged pistons are built to handle the stress. They are designed for heavy to severe duty race applications, meaning they're made to withstand the kind of demands that push an engine to its limits. Wiseco crafts these pistons from 2618 aluminum, which gives them improved tensile strength over cast aluminum, making them a solid choice for high-performance builds.

Wiseco puts a lot of thought into the details with these pistons. You'll find precision ring grooves, anti-detonation grooves, and other features to help improve ring seal, which is crucial for maintaining compression and preventing blow-by under boost. The crown of the piston is 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, resist seizure, and even makes operation quieter. These are well-built components designed for builders who are serious about performance and durability.

This set includes four pistons, each with a -22cc dish, an 87mm bore, and a 35mm compression height, along with a 0.827-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, you'll want to ensure you have all the necessary supporting components and follow the manufacturer's installation instructions carefully.
