I just found your thread today and have read the whole thing. I love it. I am in the middle of an S14 VQ swap and am finding this very helpful.
I did a diff swap that you may find helpful. Not sure if it would be good for drift. I plan on making it a Daily Driver and it might see a few track days. I was a road racer for 20+ years in the NW. Hundreds of miles around what used to be Seattle International raceway, (now Pacific?). My home track was Portland. Also raced at Westwood BC, Sears Point (Infineon) and once at Laguna Seca. I've been in Arizona for 9 years. I might have to give drifting a try when I get the car done.
To my diff. I bought a 95 Q45 diff from a U-Pull it yard for $65. The 95 & 96 comes with the 3.54 gears. It comes with a speed sensor that I hope to use when I get to that point. I picked up an S15 helical LSD off ebay. If you decide you like this option, be sure to get the stub axles with the LSD as they bolt up directly to your axles. At least they bolt up to the S14 axles. Don't know if the S13 axles are the same. The Helical diff and the Q45 pumkin fit like they were made for each other. You Don't even have to remove the pinion. Bolt the ring gear onto the LSD and drop it into the case, set the gear lash and your done. You will have to change the flange on your drive line as the 4 bolt patern is larger than the S flange. The right gears and an awsome LSD at a reasonable price. It realy is a very easy swap.
