y5 to y8 head

[alabranche]

i have a d16y5 in my 98 hx, and i want to do a mini me swap with a y8 head to gain a few horses and make it better to turbo. i know the heads basically bolt off and then put the new one on, but do i need to change the wiring harness along with the ecu (p2n to p2p)? i know i also need the intake mani, throttle body, and fuel rail as well, but i just need to know about the electronics.

thanks

if thats a Ex head your talking about you'll probably need to switch ECUs since the Hx has E-vtec its completely different from Ex vtec
