2jz swap planned for my 97 SL Limited Edition, Need some tips and pointers Options

[NewToCelicas]

Hey guys this might be too little too late to get any action from anyone, but its worth a try.
I have come into possession of a 1997 Celica SL Limited Edition (sadly its automatic too haha).

Before i get into what im going to do i want everyone to know that money is not an issue, i am getting paid well and am really pumped to start this project, so i dont need to hear about how stupid it is monetarily. Also i have access to friends that are quite skilled with welding and fabbing that are all supportive and want to help with this.

So i want to swap a 2JZ-GTE in and make it rear wheel. Im not looking to go the turbo route, but i am hoping to have at least the engine, trans and rear diff/axle from supra and maybe anything else i can make due with if possible

I would love any tips and hurdles that i may come accross throughout this project and anything that may make any part of this any smoother!

Things like the following but not secluded to:
1. cutting for the new trans tunnel
2. Is there already room for a driveshaft to fit or will i have to cut for that as well
3.Someone told me that the GT-Four subframe will bolt right up and make room for the rear diff is this true?
4. What of the interior will i have to change to make things keep looking clean and together and not disheveled
5. Should i just go with a supra ecu, or is there something else i should be looking at?

And anything else anyone can think of

Thanks for any and all help!
