HKS 256° Intake Camshaft Step 1 - Nissan SR20DET S14/S15
The HKS 256° Intake Camshaft Step 1 is designed for the Nissan Silvia S14 and S15 equipped with the SR20DET engine. Developed to improve both horsepower and torque without sacrificing drivability, this camshaft is an excellent upgrade for street-driven vehicles and mild performance builds. Featuring a 256° duration and 11.5 mm valve lift, it improves cylinder filling and delivers a broader, more usable powerband.
Each HKS camshaft is CAD-designed to optimize torque and horsepower across the widest possible RPM range. The Step 1 profile provides noticeable performance gains while maintaining smooth idle characteristics and excellent everyday drivability.
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 are designed to replace. The camshaft is a direct replacement for the factory intake camshaft and is fully compatible with the OEM valvetrain.
