Diff Ratios

Just finished putting a 5speed out of a 98 hilux 2wd into a YN57 previously auto 2wd hilux.
The speedo is out by about 10kph on the high side, does anyone know what the origional diff ratio would be and if it is worthwhile changing the ratios.
The old 3y has been dumped and a balanced 4y with a lot of headwork, cam change and a lot of expensive parts added. It is a very quick lux but could benefit with a bit taller diff.
How many 4y lux's can lay rubber in 3rd?
After ideas thanks

Most likely that the original diff ratio was 4.9 and you are running 3.9 or 4.1 now, accounting for the large difference in speedo readings.
You should have no trouble hunting up a G series hilux diff and I have a spare 4.9 at home in Perth, West. Aust.
Cheers,
Mitch.

If you just want your speedo to read incorrectly, changing the diff is a bit extreme! A more sensible approach is to change the speedo drive gears inside the gearbox, unless of course you have some other reason to change your diff ratio.

$100 (my cost) but freight for this heavy thing out of Perth would make it uneconomic mate.
Cheers,
Mitch.
