JE Pistons Ultra Series Nissan SR20DET 87mm Bore 10.0:1 CR Set of 4 Pistons

The JE Pistons Ultra Series 361307 is a set of four high-performance forged flat-top pistons meticulously engineered for the Nissan SR20DET engine. Featuring an 87mm bore and a 10.0:1 compression ratio, these pistons are designed to withstand extreme cylinder pressures in power-adder engine builds (boost and nitrous compatible). Crafted from 2618 T6 high-tensile forged aluminum using JE's proprietary Aligned Grain Flow forging technology, they offer exceptional strength and durability. Key features include thermal barrier crown coating, skirt coating for reduced friction, and lateral gas ports for optimal ring seal. The asymmetrical FSR (Forged Side Relief) skirt technology reduces friction and mass while providing a rigid and durable platform. Each set includes premium gas-nitrided carbon steel rings (1.0 x 1.2 x 2.8mm), .866 x 2.250 straight wall carbon steel wrist pins, pin fittings, and wire locks. Made 100% in the USA.
