Guys, I have TT auto which I have fitted a NA 5 speed manual box to it,the doner NA 300ZX had a 180km/h speedo and my TT has a 290km/h speedo, how do I get the calibration correct? is it a matter of fitting a resistor in somewhere?

Thanks in advance.

Cheaper than buying clocks and will cope with any changes you make in the future

as well as the difference in the speedos, the N/A and the TT have different size cogs on the speed sensor due to the different rear diff.

 

if your speedo is from a pre 1995 car then yes, change a resistor to get it roughly right and then adjust a variable resistor to get it acurate

 

it's all writen up somewhere in the FAQ

Thanks guys, cant seem to find the resistor mod, searched all the FAQ's to no avail....does anyone know the exact thread?

Cheers

or just fit a TT speed sensor gear to the NA speed sensor.

that won't work unless you fabricate a bracket to adjust the position of the sensor.

 

one cog is bigger than the other, if you put the big cog in the small hole it dosent fit, if you put the small cog in the big hole it doesnt touch the other cog it needs to touch so doesnt go round
