Newb question on "how-to" guide for ITBs on JDM 4AG Bluetop w/ MAP

-ITB (obviously)
-adapter (I would highly recommend SQ)
-velocity stacks ("trumpet")
-vacuum block (you can make it work without it depending on the setup, but it's better with it)
- you may also require a new throttle cable and some brackets depending on the application
- bolts, hoses, etc...

EFI:
-Standalone ECU (forget about piggyback, that's just a BAD idea)
-TPS (16v and 20v TPS are not the same)
-injector and pressure regulator (again, not absolutely necessary. But unless you want to go ITB just for the sound you will need them too)
-connectors

The TODA kit is nice, but expensive and still require a fair bit of things to make it work.
It's also specifically made for RHD.

The TODA Kit, what all extra things would I need? From my understanding, Greddy eManage Ultimate, the manifold port needs to be enlarged are the only things you need. Is that true? Or are there more things I am missing. I also heard a full stand alone ECU is harder to work with a JDM car because of compatibility? I imported an actual RHD AE86 from Japan which is why I’m asking.
