Tacho and speedo problems Z20

[Luisito]

Hey guys, my conversion is almost done except fot the tacho that won't read and the speedo sensor being to big so we used the jzz30 one and the speeds read at like25% less, I'm using the z30 box as well. Any help would be great cheers

You need a tacho booster for the tacho to work...

Search tacho booster and ye will find:

As for the speedo, have you checked to see what tooth count your original gearbox had? It's ussually stamped on the gear... (suspect your original will be 6teeth to 22teeth [6:22] if your car was auto originally...might be 6:21...? )

JZZ30 auto should be 6:19 if I recall...

You can't swap the gears over? (Not the whole sensor...) I thought you could...


Another option is a jaycar speedo corrector...
