Wiseco 1400 HD 1st Gen 6 Bolt 4G63 Turbo -14cc Piston Kit

If you're building a serious performance engine for your 4G63 Turbo, this Wiseco 1400 HD 1st Gen 6 Bolt piston kit is a solid choice. These pistons are forged from 2618 aluminum right here in the USA, which gives them improved tensile strength for handling the demands of heavy to severe duty race applications. The -14cc dish is designed to work with specific cylinder head configurations to achieve your desired compression ratio.

Wiseco has packed these pistons with features to ensure durability and performance. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. They also come with forced pin oiling to keep the wrist pins lubricated under high stress. The piston crowns are fully machined, and the skirts are treated with an ArmorGlide coating. This coating helps reduce friction, resist seizure, and contribute to quieter operation, which is a notable benefit when you're pushing an engine hard.

This kit includes four pistons, each with an 85.50 mm bore and a 35.00 mm compression height. The pin diameter is 0.827 inches. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for serious builders who need reliable components for high-performance sport compact applications.
