Intercooler kits will need to be modified but all other parts do not matter as long as they are for the S14 motor.
I dont know where you could find a wiring diagram specifically for making a S14 SR to S13 harness. If you have the US S13 factory service manual and you know how to read the wire diagrams, S14 SR20 factory service manuals in english are readily availible on the internet, you could put it together using both.
