Honda did a good job engineering the B-series' timing belt configuration. For the average commuter who replaces their timing belt on a regular basis and doesn't spend the majority of engine operation in the 8,000rpm zone, the OEM setup is just fine. But high-rpm engines can stress Honda's belt in ways B-series engineers never imagined. Making sure that the belt is replaced on a regular basis; that the OEM tensioner is installed correctly and in good working order; and accompanying the system with a supplemental tensioner like Vibrant's is a good start to ensure the timing belt is the last place you'll find your next problem.
