Stage 2 2.0/2.5 VCT Duratec Camshafts (+20-30hp Over Stock)
Stage 2 Camshafts — MX-5 NC 2.0 / 2.5 VCT
Performance Redefined
Our Stage 2 camshafts are engineered to unlock the true potential of the Mazda MX-5 NC’s naturally aspirated Duratec engine. Designed for enthusiasts who demand sharper throttle response, stronger mid-range torque, and harder top-end pull—without compromising reliability. Extensively tested on both 2.0L and 2.5L VCT engines, these cams deliver ~200 hp on the 2.0L and ~220 hp on the 2.5L, offering a +20–30 hp gain over stock, depending on tune and rev limit.
Built as a direct drop-in solution, they require no valve adjustments and are fully compatible with stock pistons and valve springs. A new VCT timing map and ECU remap are essential to extract full performance and ensure perfect synchronization with your engine setup.
