JE Pistons Ultra Series Nissan SR20DET 86mm Bore 8.5:1 CR Set of 4 Pistons

JE Pistons is well-known for building strong, reliable engine components, and their Ultra Series pistons are a prime example of that commitment. If you're working on a Nissan SR20DET and planning for serious power, this set of four pistons is designed to handle the extreme cylinder pressures that come with high-boost applications. They feature a specific bore size of 86mm and a compression ratio of 8.5:1, making them a solid choice for builds aiming for significant horsepower gains.

What sets these Ultra Series pistons apart is the advanced technology packed into them. They use JE's proprietary Aligned Grain Flow forging process, which maximizes tensile strength to withstand the intense stresses of performance engines. You'll also find a thermal barrier crown coating that reflects heat, helping to keep piston crown temperatures down and improve exhaust gas scavenging. For added durability and reduced friction, the piston skirts are coated, and they include lateral gas ports to help maintain a strong ring seal even at high RPMs and under heavy boost. These pistons are built with high-strength, thick-wall wrist pins from Trend Performance, ensuring they can handle the demands of power-adder builds.

This set is made 100% in the USA, reflecting JE Pistons' dedication to quality manufacturing. Remember, these pistons are not CARB approved and cannot be shipped to California. For a high-horsepower SR20DET build, these pistons offer a comprehensive package of features designed for performance and longevity.
