JE Pistons Nissan RB26DETT 8.2:1 86mm Bore 15.3cc Dome - Single Piston

If you're rebuilding the engine in your Nissan RB26DETT, especially for a high-performance build, a solid set of forged pistons is crucial. These single pistons from JE Pistons are designed to handle the demands of boosted and high-RPM applications, offering a significant upgrade over stock cast pistons. They feature an 8.2:1 compression ratio with a 15.3cc dome, making them suitable for forced induction setups where you need to control detonation.

Crafted from 2618 aluminum right here in the USA, these pistons are well-built for durability under stress. JE Pistons uses a proprietary Forged Side Relief (FSR) design that helps minimize friction and power loss by reducing skirt width. Some applications also include a skirt coating to further cut down on friction and wear, while also making the engine run a bit quieter. An accumulator groove is also included to help manage combustion gas pressure, which improves ring seal and keeps power consistent.

This piston comes as a single unit and includes high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
