GReddy Aluminium Pulley Kit for Mazda RX-7 FD

GReddy Aluminium Pulley Kit for Mazda RX-7 FD3S SpecificationsThis GReddy pulley kit has been specially developed for the 13B-REW of the Mazda RX-7 FD3S. Thanks to their design in duralumin (an alloy made from aluminium copper magnesium and manganese) with a blue anodised finish these pulleys are as light as they are strong significantly reducing the inertia momentum of the engine's axis of rotation. Power losses are minimised and throttle response is improved. Please note that this kit does away with the original air pump.Kit contents :Water pump pulleyAlternator pulleyBelt
