Hi all, I have been given some man Vitara front diff heads and want to put them in my Samurai. My current set up is 1.6 Vit motor, 1ltr transfer case , 2inch sus lift , 2inch body lift, Vit power steer, 31's . Now if I chuck in the crown wheel and pin's out of the vitara what's my top end going to do?, maybe 32's,33's could be on the cards? or should I go back to a Samurai transfer case?

Did the calculations. Your current RPM at 100km/h is about 3500. Your new RPM with the 1.0l case and 5.12:1 diff gears will be about 4750, or in other words, revving its nuts off If you put a standard transfer in with 5.12:1 diff gears your RPM will be 4250, so not much better. I think you would be much better to just leave the diffs alone and either buy transfer gears or do a rocklobster because at the moment your high range gearing is about standard so you probably don't want to change it.
When I did the calcs I used the numbers from the factory owners manual and I got the 1.0l transfer ratios from one of 303zukes posts.

You'd have AWESOME acceleration in high though!!

And what size tyres did you use for those calculations, Al

31"

And with 33's with 5.12 diff gears and 1.0l tcase the revs at 100 will be 4500. With a standard tcase and 5.12 diff gears it will be about 4000.
