Nice write-up and nice job. I have a question, though. I'm going to be doing something similar when I can tear myself away from other pursuits long enough. I'm going to be going the other way with gearing, since my car is mostly a long-haul highway car these days. I'm pulling the current 3.45LS and putting in a 2.93LS from an e30. (I ought to get to it someday - the e30 diff has been sitting on the floor of the garage for nearly a year...)

My question is this: Did you purposely decide not to swap the speedometer blipper wheel? The blipper wheel on the e30 diff is different than the blipper wheel on the e23 diff... or so I've been told for many years. Did you count the 'teeth' on the two blippers and find them to be the same? Or did that not concern you? I've been told that the e30 blipper has one less 'tooth' than the e23 blipper, which will effect the accuracy of your speedometer and odometer.

Not trying to be belligerent - just wondering if what I've been told from several sources about the difference between the e23 blipper and the e30 blipper has been wrong all these years...
