What is the torque curve on a 2008 MX-5 Grand touring?

You can find it at Flyin' Miata and maybe Goodwin's, as they both sold the Cosworth SC kit that displayed before and after torque curves for the NC1 and NC2 MZR motors. The gross torque was only 142 or 148 ft-lbs (can't remember), and GREATLY increases with the Cosworth. But satisfying mods with much higher bang-for-the-buck start with fatter anti-swaybars and maybe Goodwin's simple weight-saving street race single muffler. Great affordable mods. Don't bother with a fatter mid-pipe or especially a long-pipe header as you will REDUCE torque until upper RPMs. Avoid a CAI as well, as it doesn't help. Street racers prefer 235/40W70 rubber, but the 205/4517 (or even non-GT 215/50R16) rubber is fine. If you have money to spend get new springs/struts from FM or Goodwin's, as well a better front crossbar brace. Then if you really want more power see if you can find a leftover Cosworth kit somewhere, and pay for a tuning, as they're not on shelves anymore. As designed, the Miata is a momentum car. Mods that increase power are comprehensive and expensive, not piecemeal. Always start with the chassis, exhaust and better rubber first. I like the Kosei sub-15lb wheels a lot. Have fun.
