I was wondering if you are able to calibrate the speedometer after this?
I know after changing gears the speedometer can be really off. I have contacted some reputable (3 competent) shops in my area and they weren't able to fix this. I was quite surprised.
Any recommendations on how to fix the speedometer problem? This was one of the biggest issues I had that prevented me from doing the swap.

There is no speedometer problem. These cars use the ABS (wheel speed) sensors to determine vehicle speed, not a dedicated sensor in the transmission. Since changing the final drive doesn't change wheel diameter, the speedometer is not affected.
