TODA RACING F20C/F22C Toda Racing Heavy Duty Oil Pump ChainAdvanced punch manufacturing techniques used in the making of the TODA Heavy Duty Timing Chain have improved accuracy and reduced edge burrs leading to reduced friction and smoother chain operations. An important component that's often overlooked when building high power S2000 engines is the Timing Chain & Timing Chain Tensioner. The additional stress placed on the factory Timing Chain Tensioner while employing high lift camshafts can lead to
