The Greenfield Fire Territory participates in the Hancock County Technical Rescue Team. The Team was created to pool the resources of the Greenfield Fire Territory and the Sugar Creek Township Fire Department to enhance the response to technical rescue situations. The Greenfield Fire Territory is the busiest fire department in Hancock County, responding to more than 3400 emergency calls annually. Approximately 80% of those calls are emergency medical responses.
The US service manual states that the timing belt should be replaced at 72 months (6 years) or 90,000 miles. The vast majority of NSXs hit 6 years well before they are anywhere near 90k miles so many owners are wondering if they really need to change the belt at 6 years.
but specifically, i see there is no recommendation for belt change on the 3VZ-FE. if i can trust http://www.autozone.com/autozone/ which in this case, i really don't believe it. if you were to go by the 3VZE schedule (truck version- basically same engine-less valves and different cam), it would be every 90,000 miles.
