JE Pistons Nissan SR20DET 90mm Bore 8.5:1 CR -16.9cc Dome KIT Set of 4 Pistons

These JE Pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for high-demand performance applications like your Nissan SR20DET. This specific set is designed for a 90mm bore with a compression ratio of 8.5:1, featuring an inverted dome that displaces -16.9cc. This design helps manage combustion pressures and can contribute to optimized performance and durability in a performance-built engine.

JE Pistons brings over 75 years of experience to their forged piston designs, and these are no exception. They feature a proprietary Forged Side Relief (FSR) forging design, which works to minimize friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also helps save weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce pressure from combustion gases, leading to better ring seal and consistent power. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down operating noise.

This kit includes everything you need to get your SR20DET engine rebuilt with these performance pistons: four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. All JE Pistons are engineered, forged, and machined 100% in the USA, ensuring they are specifically designed for your engine and use application to provide optimized performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California.
