Well after years of waiting and planning I have finally installed my upgraded motor and I am more than satisfied with the spunk and pep my Sami now has. Turning the 33" tires was just too much for the 1.3. It can spin the tires with ease. However I still need a little more speed on the highway. There are soo many ways of gearing that it has boggled my mind. I am looking for practicle info from someone who has been thru this predicament. I do agree with the fact that both the transfer case gearing and differential gearing need to be changed. This I cannot afford to do all at once. So, not only do I need to know which to do first, but also exactly what gearing I should install in each. As far as transfer case should it be 6.5 to 1 or 4.6 to 1. Or something even different. I don't have any idea on the diff gears in my stock Sami housings. My offroad plans are going to be mostly mud and rock crawling. any specific help would be most appreciated.
