Well you will need all the key components for an EFI system to run, trigger inputs, map, tps, temps, injectors, coils etc etc, but they are easy to work out from the ECU pinouts online.

You can use the dizzy if you like, however if going standalone its worth swapping to COP, namely for knock control id say, however there are plenty other benefits too.

have not got my car going yet but the plan is....

skyline spec 1 throttle position sensor, oil pressure sensor, wideband , intake air temp, wideband, coolant temp

(I've probably missed one or two) Most of the old toyota sensors are gonna be on their way out and half \arent needed on standalone

 

link atom can run coil packs too

Really is the tps straight bolt up is it variable or open close was just going to use what is there get it up and running and replace as it fails I work for Toyota so can match with new stuff as for size and work out wiring later. What's with the wideband differences

Id avoid an Atom on a boosted car personally if you can, only has open loop boost control so very limited. Like you say you then dont' have much I/O either but it does work.

You can use a switch type, open/closed TPS as the main load axis is MAP, however again, its not recommended as the majority of the other strategies work of TPS %, so you really want to change to a variable TPS.
