JE Pistons Nissan SR20VE Ultra Series 87mm Bore 1.260 CD 0.866 Pin Piston Kit (Set of 4)

This is a set of four JE Pistons Ultra Series pistons, designed for Nissan SR20VE engines. You get the pistons themselves, along with high-strength wrist pins, and specialized coatings applied directly from the factory. These aren't just basic replacement pistons; they're built with advanced features for serious engine builds, especially those planning to run high boost or significant power adders.

What sets these Ultra Series pistons apart is JE's proprietary Aligned Grain Flow forging process, which gives them exceptional tensile strength to handle the extreme pressures found in boosted engines. They also come with a thermal barrier crown coating that reflects heat back into the combustion chamber, helping to keep piston crown temperatures down and improve how efficiently exhaust gases are scavenged. The skirt coating is there to reduce friction and wear on both the piston and the cylinder walls, which also helps quiet things down, particularly during a cold start. Plus, they've got lateral gas ports to help maintain a solid seal on the top compression ring, even when you're pushing high RPMs and boost.

These pistons are made 100% in the USA, and they include optimized pin oiling features to ensure the wrist pin and connecting rod small end stay well-lubricated under demanding conditions. Keep in mind these are not CARB approved and cannot be shipped to California. If you're building a high-horsepower SR20VE, these pistons are a solid option to consider for the foundation of your engine.
