Timing your MZR or Duratec engine isn't like the older MX-5's. These engines are what's known as "keyless" timing systems. That means as soon as the hardware is loose on your crank or cam gears, the timing must be held in place with these, highly accurate specialty tools. Unlike some timing kits, this set includes the pin used to lock your chain tensioner for easier installation.
