I have a 1995 Honda prelude with a H23 and im wanting to swap in a JDM H22 VTEC the motor im buying is an Automatic and mine is a five speed. what is all the wiring problems that im am going to have in doing this swap. I have also thought about using the h23 block and the h22 head is this worth the time and effort and if so what kind of wiring will need to be done in order to make this work. If some one would be able to post a link for the pin outs on both ECUs. Will I be able to use the Auto ECU with the 5 speed tranny when i do this swap?

 

ima say it......

search. for real.

this topic has been beat to death.

and plus, you'll find much more info, than what will be posted in this one thread.

but no, u will not be able to use the ecu. and you will use your old wiring harness, with just running wires for vtec.
