For the electrical, you'll only need to run 3 wires to the ECU for vtec.


depends if u tun the ecu u can make it pop by just running the vtec wire

There is no need to tune when your running the correct ecu for the motor. If he plans on building the motor or getting a turbo then yea he might want to look at hondata s300.
