coldbluesteel,
I am pretty far along stuffing a 93 1UZFE from an LS400 into my 83 RA65 Celica. You can find 2 threads on my car here with pics. I also bought an entire LS400 donor car. It certainly made it much easier since I had no choice but to use the stock injection and trans. I am in California and it has to make it past the smog check. Depending on the year, there are some electronic bits all around the car you may need. In the 93, I had to get the Fuel Pump ECU, yes, a separate computer, just to run the pump, that was in the trunk. It was behind the CD changer that was totally crushed in the crash. The FP ECU was fine, but even the CD's in the changer were not. If you are doing the manual trans and futting a progammable ECU, then you don't need near as much suff out of the LS400. I still have my W58, incase I later want the manual again.
As for the diff, DON'T go to a 4.XX I am concerned my 3.727 will be too low of a ratio. The 4000 pound LS 400 used a 3.62 with taller tires. I will run it with the 3.727 for a while, but I may end up getting a 3.58 if I can find one for a fair price. My car has IRS and has a Supra F series 7.5 inch LSD setup. It uses the same gears as the live axle F series that was in most 4 banger trucks. My turboed 22R ripped the teeth out of the original 3.42 T series 6.7 inch diff.
On the V8 in a Celica... The driver's side exhaust manifold will be a custom job. There is just no room in there.
Have fun. I will actually get to drive mine in just a few days. I live in Cali, but the car is still in Illinois.
