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

Starting with a 2618 aluminum forging, these JE Pistons are built for serious performance in your SR20DET engine. This set is designed with a 10.00:1 compression ratio, a flat-top design, and a 3.406-inch bore, making them a solid choice for rebuilding or upgrading your four-cylinder engine. JE Pistons has been in the forged piston game for over 75 years, and they engineer and machine these right here in the USA, specifically for each engine and application to balance durability with performance.

You'll find JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a shorter wrist pin and reduced skirt width, also saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise. This kit comes complete with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, so you have the essential components to get your engine back together.

Because these are forged pistons made from 2618 aluminum, they offer the high tensile strength needed for demanding performance applications, whether you're on the drift track or the drag strip. Keep in mind that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
