Drop-in cam to suit factory valve springs. Excellent throttle response and improved low to mid-range power. Wider power band using NVCS. Ideal for small frame turbo 46mm-54mm. Must retain stock rev limit and not exceed 22psi of boost with OEM springs. For high mileage engines or higher boost Kelford Cams recommend KVS93 or KVS93-BT valve spring upgrade. \n \n
