AA60 t50 vs AE86 t50

[AE85.6]

just wandering if the ratios are the same or whether the AA60 one was geared with 13s instead of 14s or something like that ?

or do they have a different size gear on the speedo drive or something as they read like 20kph different ?

cheers

Identical ratios in the gearbox.
The speedo gear on the output shaft depends on the diff ratio of the original car the gearbox was fitted to. Off the top of my head the AA60 had a 3.9:1 ratio (code T312) diff... the AE86 came out of the factory with either 4.1:1 (code T292) or 4.3:1 ratio (code T282). Factory tyres where the same diameter as far as I remember (don't quote me on that!).

4.1 in my old aa60.
3.9 is good!

ah ha i see, cause the extra gearbox was ex a carina, however it had no speedo drive so i used an 86 one, which has made it read approx 20kph low, easy way to remedy ?

You can get it calibrated, a place in auckland called Speedo Calibration services were gunna do mine, its around $50 from memory. Can find out more if youre keen.

Could well be wrong though, was a while back.

but ye any details would be awesome cheers,
