Speedo Calibration
Hey, i just took the speedo drive out and im wondering what size i need to put back in. When at 60km/h my speedo reads about 60km/h and at 72km/h it reads 60 and at 95km/h it reads 80km/h. Thats out by 19.2% lol. Will i need a bigger or smaller drive? And how the F**k is it out that far.

You've put a speedo from an entirely different vehicle (albiet a Suzuki) into your car, connected up to a non-original gearbox (F8B-box) and have over-size tyres fitted, and you wonder why your speedo is out...?And how the F**k is it out that far
Wanna have another think about that...?
The Jaycar Kit might be a good solution to your miss-matching efforts tho!
Good luck!

The Jaycar kit only works on cars with electronic speedometers. You're shit out of luck Billie!
The only option is to try and calculate what size speedo drive you need, or take the cluster to a recalibration specialist and have them work it out and modify the speedo. To work it out you'll need figures on the rolling diameter of the wheels, the speedo drive ratio, final drive ratio and of course the cluster ratio.

F8B EFI turbo - Three pots and a snail.
But the revs per km are both the same from the original unit to the alto unit.
I have all those figures except the drive one, i have the driven which is the speedo end and the revs per km and tyre size. What is the drive one?

or put it on a dyno and get it dyno'd for a power run and ask them to get the speeds at certain speeds and then they can send that away and get an adapter thing to change the speedo to correct. this is what my dyno bloke told me when i asked about my sierra

There is another answer, you can use a ratio box similar to those supplied by Marks Adaptors or get in touch with Lionel Otto Instruments at Salisbury http://www.ottoinstruments.com.au
So many delays to getting my MB back in order with 993cc & 5 speed transaxle... neighbor issue gone, donor shell up on rotisserie, new sheds on the way.... another project also..
yeah thats the thing i was talking about, not sure if i made sense tho.gadj wrote:There is another answer, you can use a ratio box similar to those supplied by Marks Adaptors or get in touch with Lionel Otto Instruments at Salisbury http://www.ottoinstruments.com.au

I dont think the speedo is broken, just not working to well lol.
I was lookin at the digital ones, but im abit weird with things, thats why i like the alto cluster, all the rev counter, speedo, temp and fuel are in one thing, dnt like having rev counters off to the side. The hatch digi dash doesnt have a rev counter lol. I'm pretty sure its coz i have a massive wheel change, 54mm bigger than stock.
Is it possible to change the actural speedo its self? I know it comes out and all, but would another from a diff car fit?
Me thinks the skyline 300km/h would look great

doubt it, the skyline one would be an electronic speedo... not cable
That is the main reason I suggested Lionel Otto (might be another instrument repairer closer) They will most likely be able to repair, rebuild or modify your speedo thus keeping things simple
