I am currently in the process of dropping a b18c itr in my 2000 civic si. everything is going great. both motors are currently out of the car and i am getting ready to drop the itr motor in the car. I have run into the problem of matching some wires with my ecu though. I need a pin out of the P73 ECU. if anyone has or knows someone who can help please tell them to email me the information at (jd5178@ship.edu). This is going to be one bad *** swap and i cannot wait to post some pics and reviews of the swap. Thanks to all who take interest in helping me.
