If going for more of a full car re-wire with almost everything controlled by the ECU, then you need to add a dedicated PDU on top of the R5/R3 either way.
I know an R3 will fit in stock location. Still trying to figure out R5 / PD16 location. Probably battery in one bin and electronics in the other. Or find a way to use the glove box area.

18 XX racing injectors (2ohm coils) will pull 32 amps at 75% duty at 9000rpm so that goes past the limits of the single output,

i dont know what you guys are putting in all your "Street" cars to require more outputs...
take this example... full street car, indicators, head lights, tail lights (even this shitty usa ones that take up extra outputs) DBW etc etc 2 speed elixer fuel pump module (uses 2 DPOs)
only thing that is not off the ecu is the power windows which i could have done but the owner alredy had them wired to the power post...

at 12v a 15ohm injector uses 0.8amps. x4 if you had a typical 13B, 3.2amps.
you'd want some safety factor, so maybe you have it on a 10a circuit? Mazda had it on a 30A circuit, but its the injectors and all of the solenoids and the air pump, so its like 0.8 amps times the 23 things on there, or about 23amps

the injectors are kind of simple, you use Ohm's law. V=i/r, or in our case Amps = Voltage/ Resistance

just finished wiring up another car with and R5 and NO PDM...
full street/strip 2012 camaro, low beam, hi beam, USA tail lights that flash the brakes as indicators that uses up 1 extra output, fog lamps, exhaust cutouts, wipers, line lock, water pump, thermo fan, trans fan, trans brake, 8 coils, 16 injectors, even powered the power windows off the r5 using a switch over digital relay... only thing i couldnt do off a hco was interior light, but i will use a LED light and a DPO and power coming from the power window supply which will be fine with no relay

Lots of it comes down to E-experts and Inexperience.
Like people running 70amp relays for 4 IGN1A coils lol

i dont know how much more modern you can get than a 2012 Camaro but zero issues running everything off it.. dont know how much more street you need to be but lo beam, hi beam, blinkers, fog lights, tail lights makes it pretty street car...
