I have a 95 civic ex 1.6L V-TECH with DC header, full exhaust, getting and password JDM intake, AEM throttle body spacer and skunk2 intake manifold that has a 64mm opening. I want to get the skunk2 throttle body as well but I don't know what size would be better the 66mm or go bigger to the 68 or 70mm? I plan on doing Skunk2 stage one cams and getting the car tuned later the summer and a possable yurbo kit next summer. Is the 66mm going to be good or should I go bigger. (do the new throttle bodies come with a new throttle plate positioning senser on the throttle body, the one on the stock unit as far as I know doesn't come off easly) Any other input would be great too. Thanks josh

 

The 70mm TB is gonna be overkill on ur ciivc most likely. Its a Sohc d series right? stock is 58mm righ? id go with a 66 or 68mm TB with ur skunk intake mani.
