are you asking if you need the timing belt, or if that charge is normal. yes you need it, if you break the timing belt you buy a new engine. (recommended interval is 105k miles) The price is high but not actually too bad for a dealership charge. There is a fair amount of work involved with the timing belt. You might be able to find it $100 or $150 lower if you shop around, but it won't be drastically cheaper.
