JE Pistons Nissan FJ20 89.5 Bore +.50 Oversize 9.5:1 CR -2.8cc Dome (Set of 4 Pistons)

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've applied that experience to their extensive line of pistons for import engines. This set is specifically made for the Nissan FJ20 engine, featuring a 3.524-inch bore size, which is 0.050 inches larger than stock. The 9.5:1 compression ratio is achieved with a -2.8cc inverted dome design, making these pistons a solid choice for performance builds where you need more displacement and a specific compression target.

These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is essential for the demands of high-performance applications. JE Pistons incorporates their proprietary Forged Side Relief (FSR) design, which reduces skirt width and uses a shorter wrist pin to minimize friction and save weight. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, improving ring seal and preventing flutter. A skirt coating is also often included to further reduce friction and wear on the 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, ensuring you have everything needed for a proper installation.

Because these pistons are designed for high-demand performance, they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding installation procedures and any required hardware or modifications.
