Wiseco Nissan SR20 Turbo -17cc w/92mm K1 Crank Piston Shelf Stock Kit

If you're rebuilding the engine in your 1991-2002 Infiniti G20 for serious performance, especially with a turbo setup, you're looking at a critical component: the pistons. This Wiseco kit is designed for the demands of heavy to severe duty race builds, giving you the foundation for significant power gains. These aren't your average pistons; they're crafted to handle the stress and heat that come with pushing an SR20 engine to its limits.

Wiseco forges these pistons from 2618 aluminum right here in the USA, a material known for its strength, which is essential when you're aiming for high horsepower. They feature a -17cc dish to help achieve your desired compression ratio with a 92mm K1 crankshaft. The piston crowns are fully machined, and the ring grooves are precision-machined for a solid seal, incorporating anti-detonation features and additional ring seal improvements. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. This kit comes complete with a premium ring pack, pins, and locks, so you have everything needed for a proper installation.

This set is specifically for the SR20 engine platform, common in performance builds for the Infiniti G20, Nissan 200SX, and Sentra. Remember, these pistons are intended for competition use and are not CARB approved, meaning they cannot be shipped to California. Ensure you consult your engine builder or a trusted mechanic for specific installation procedures and compatibility with your build.
