Speedo wrong 2jzgte jza80 conversion

[steadyeddie]

Hey guys!
Got something I need help with!

Since the 2jzgte was dropped in the 93 supra the speedo is about 10ks slow at 80km/h but it's about 20ks wrong at 110km/h.

What I intend to do is either get bigger wheels or fix the speedometer, or both!

Any Info on typical solutions or wheel circumference/diameter would be appreciated!

Thanks in advance!!
Ed

remove the speedo drive from your old gbox and fit it to the new one
the gear inside it probably has 1 less tooth which means yr speedo will be 10 % faster
or just fit a jaycar speedo correction box
