nope.. no change there.
If you're planning on getting a whole front clip, use the transmission off of that, as the stock 1st gen trannys are much weaker (much over 200hp they start exploding). The only downside of using the turbo tranny is that it is longer and will require a custom length driveshaft (not too bad.. any offroad truck guy has to do that anyway) but it's a couple hundred bucks ontop of everything else..
Most of the info you'll ever need can be found (or linked to) in this thread in the 1st gen archive;

Standalones are more complex for sure.. but if you're going to do a full swap, then wiring up all the proper sensors from the turboII will get to be a pain as well... That is a lot of work for an ECU that will quickly become the limiting factor to making more power..
I've sat down with my mechanic (who already has a 387rwhp 13B Turbo 1st gen) and I came up with about $7k total outlay to do the project as I wanted (standalone, 60-1 turbo, FMIC etc etc etc. Should be 350+rwhp) And easy $3500 just to get a J-spec bolted up and running.
