h23 to h22 ecu questions

i hunted for an answer for a while and came up with a lot of almost answers. please bear with me, i am not familiar with the prelude and the minor differences between the si and the si vtec cars.

i have a 92 prelude si, 5 spd, w/h23. motor is shot! gonna sell the car but the buyer wants a h22 put in instead (for more money of course). now the h23 car obviously is not vtec, so if i buy a complete h22 longblock, are the only wiring differences the 2 wires connecting the vtec? if not can someone point me in the right direction.

question in a nutshell is: if i put the h22 in the car, hook up to the factory harness, swap over all the accessories, plug a vtec ecu in, and add the vtec wires is that all i need? assuming of course the engine is good.

of course i will have the service manuals handy while doing this.

if anyone has any input feel free to email or post

thank you
