HKS 256° Exhaust Camshaft Step 1 - Nissan SR20DET S13/S14/S15
The HKS 256° Exhaust Camshaft Step 1 is designed for the Nissan Silvia S13, S14, S15, and Nissan 180SX equipped with the SR20DET engine. Developed to improve exhaust flow while maintaining excellent drivability, this camshaft delivers noticeable gains in horsepower and torque without compromising idle quality or everyday performance. The Step 1 profile is ideal for street-driven vehicles and mild performance engine builds.
Each HKS camshaft is CAD-designed to optimize torque and horsepower across the widest possible RPM range. The improved exhaust valve timing enhances cylinder scavenging, allowing the engine to breathe more efficiently and produce increased power, especially when combined with other performance upgrades.
Unlike reground factory camshafts, HKS camshafts are precision-machined from brand-new billet cores manufactured from a high-nickel iron alloy. This construction provides exceptional strength, precision, and durability, meeting or exceeding the quality of the original equipment components they replace. The camshaft is a direct replacement for the factory exhaust camshaft and is fully compatible with the OEM valvetrain.
