Any ecu for the SR will do the trick, in this case S14 ecu to control vtc.
As for wiring, you'll need to switch the cas wiring to the back and add a set of wires in case you want to switch cams individually. If you have a non vtc sr, you'll need to add wiring to the solenoids.
P11 head is already great, P12 is marginally better but you'll need deep pockets...
