Pics
I have posted 5 pics to show what I am working with, already had a full complete tune up, wires spark plugs, next will be chip, injectors , but wanted to know if I put 97 supra injectors, would I be dumping more fuel, and if God willing some cams....and my final question, would be what's a good brand for a complete turbo kit, and do I need to swap the rear pumkin, for a 97 na pumkin , or a tt pumpkin , if some one can please help a brother out

Problems:
1. very limited room in the SC engine bay, it has to accommodate some extension of both exhaust manifolds (the original logs modified, reversed logs, tube header) and combine their discharge, then get this to a turbine inlet.
2. no place to put the turbo.
3. the stock 10.4:1 compression ratio is too high for much boost, the GTE works well at 8.5:1.
4. the later factory rods are lighter, but is this safe? I don't know.
5. cams are $$$$$ and probably very little help on turbo.
6. electronics = $$$.
7. bigger fuel pump.
8. your diff is (probably) strong enough, nothing that bolts in is any stronger. With some mods you can use the larger Supra TT 6MT (only) diff, but easily $1,000 used.
Reasons why 2JZ-GE is so common:
1. much less work to transplant GTE engine
2. lots of aftermarket stuff
3. anything you can think of has already been done - fewer mistakes

There is so much wrong with this post idk where to start. Too much misinformation spread. The op should join the fb groups for the sc 400 turbo. There are plenty of examples of how it can be done.

it can be done but there is no kit you will have to fab it or get it fabbed. it's difficult to keep a/c with some turbo header setups.
the ecu and injectors are possiblly the easiest part of the whole setup so it sounds like you need to do a bunch more research, the info is out there.
