JE Pistons Nissan KA24DE 89mm Bore 11.5:1 CR -13.5cc Dome Piston Kit (Set of 4)

Forged from 2618 aluminum, these JE Pistons are built for serious performance in your Nissan KA24DE engine. This material choice gives you the high tensile strength needed for demanding applications, ensuring these pistons can handle the stress of increased combustion pressures and higher RPMs. This specific kit is designed for an 89mm bore and features an 11.5:1 compression ratio with a -13.5cc inverted dome, which is a key detail for tuning your engine's power output and response.

JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons 100% in the USA. They utilize a proprietary Forged Side Relief (FSR) forging design. This advanced design helps minimize friction and power loss by using a reduced skirt width, and it also saves weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps reduce combustion gas pressure, preventing ring flutter and improving the 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 lead to quieter operation.

This kit includes everything you need to get your engine rebuilt: four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. Remember, 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.
