You have to replace the Honda timing belt according to the maintenance schedule. It is a wear item and it will fail eventually, and the pistons will do bad things to your valve train. They are highly stressed motors. 100 hp / liter is not easy to achieve in such a lightweight, tractable, and low emissions package. But if you take care of them they will last. I've never heard of a timing belt failure on a Honda which was not caused by PM negligence.
