monty69 6 Posted August 21, 2008 I fitted a s16 gearbox a while back and i think i fitted the top part of speedo/cable drive from old box(s16 box didnt come with one). What do i need to do to get the speedo to be accurate as its currently reading about 10mph too high at 70mph? Share this post Link to post Share on other sites

vickiw106 1 Posted August 23, 2008 you have to mactch the drive gear that sits inside diff housing with the pick up gear and sensor there are two different ratio's it will work for a certain amount of time until the gears wear/brake (because of the different ratios. with the different ratios it will effect the speed on your clocks my friend has does the same in his rally car. swopt both drive gear it worked and showed the correct speed hope this helps Share this post Link to post Share on other sites
