Wiseco Nissan SR20 Turbo -12cc 1.260 X 8625 Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of a serious SR20 turbo build. The 86.25mm bore size is a common upgrade for SR20 engines, and the -12cc dish volume is designed to work with specific compression ratios for boosted applications. Wiseco machines these pistons in the USA, ensuring precise dimensions for optimal performance and durability.

Beyond the strong aluminum construction, these pistons feature a host of details aimed at improving ring seal and longevity under high stress. You'll find precision ring grooves, anti-detonation grooves, and features designed to enhance ring seal. The crown is fully machined for accuracy, and forced pin oiling helps keep the wrist pin lubricated. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction and resist seizure, contributing to quieter operation and improved durability in severe duty race applications.

This kit includes a set of four pistons, ready for your performance SR20 engine build. Please note 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.
