JE Pistons NIS SR20DET 10:1 KIT Set of 4 Pistons

Starting with a 2618 aluminum forging, these JE Pistons for the Nissan SR20DET engine are built for serious performance. The material choice here is key; 2618 aluminum offers high tensile strength, which is exactly what you need when you're pushing an engine hard. This set is designed with a 10.00:1 compression ratio, a flat-top design, and a 3.386-inch bore, making it a solid choice for rebuilding or upgrading your SR20DET's bottom end.

JE Pistons brings over 75 years of experience to the table, and it shows in their proprietary Forged Side Relief (FSR) design. This isn't just about making a piston lighter; it's about minimizing friction and power loss by reducing skirt width and using a shorter wrist pin. Some applications might also include an accumulator groove, which helps manage combustion gas pressure to prevent ring flutter and maintain a consistent seal. If your specific kit includes a skirt coating, that's another layer of protection, reducing friction and wear on the cylinder walls while also helping to quiet down the engine's operation.

Everything you need to get these pistons installed is included. This set comes complete with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. These pistons are forged and machined 100% in the USA, ensuring a high standard of manufacturing. Please note that this kit is not CARB approved and cannot be shipped to California.
