Toyota Speedo

[88FOUR]

Linking newer model engines with an electronic speedo into older model toyota with a manual speedo . surely this has been done on many of the modified toyotas on thbis sight, just like to have more info thrown around about what had to be done when bridging the old to the new and get the dial working.

The first step is easy, driving the speedo.
Harder step is driving the ODO.

This has not been done on this site before, afaik
I'm' currently converting my MA61 to use an electronic signal instead of cable, however it has a digital speedo, so alot less work.

Easiest way would be to source a kit which does this. Or even make it yourself.
Take in the speedo signal and use that to drive an electic motor which spins the cluster.

If thats the case, I'd stick with cable drive cos why would you want a motor wizzing about behind the dash.

I have the st205 engine gearbox and ecu. the car is an 88 st165 have been told that the speedo wire from the speedo head needs to be pluged into the ecu body plug 3rd row from the top. Yet will this make the dial show my speed. ? thats me problem, getting it to work

there should be a wire from the cluster to the ecu
you should be able to use a mechanical speedo sensor in your box, which will then attach then allow you to connect up your cluster as per before.

if you have your old speedo sensor, see if it can bolt in. i'm not sure about the gt4 boxes, but with the s5x boxes, the speedo sensor can be swapped over without any problems.

The shop that did my conversion took the shaft and gear off the mechanical speed sensor, machined the shaft and fitted them to my electronic sensor. Can't say if it's accurate cause the diff and tyres were already causing the speedo to be out slightly.
