Wiseco Nissan SR20 Turbo -12cc 1.260 X 86MM Piston Shelf Stock Kit

When you're building a serious performance engine for your 1991-2002 Infiniti G20, starting with the right pistons is crucial. This shelf stock kit from Wiseco includes four forged pistons, each measuring 86mm in bore diameter with a -12cc dish volume and a 32mm compression height. These pistons are designed for the demands of heavy to severe duty race applications, meaning they're built to handle the extra stress and heat that comes with boosted SR20 engines.

Wiseco crafts these pistons from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for high-performance builds. They feature precision ring grooves, anti-detonation grooves, and other features to improve ring seal, which is vital for maintaining compression and preventing blow-by under extreme conditions. The fully machined crown and forced pin oiling further contribute to their durability and performance. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, keeping your engine running smoothly and reliably.

This kit is a solid option if you're rebuilding the top end of your SR20 engine for racing or serious performance. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
