newbie here. i've done several search but still have no confirm answer to couple of my question. i got a ex coupe civic usdm and just purchased a jdm 99 type r complete motor swap. i have couple of question i need resolve before performing the swap. i hope you guys can help me out. 1. OBD1/2: i got a OBD1 system on my 95 civic coupe and the dc type R is OBD2. what exactly will i be needing to convert it to OBD2 or is it better for me to stick with OBD1. 2.wiring/harness: can i use the ex usdm wire harness and make it work with the jdm type r or do i have to use the jdm type r harness. 3.ECU: do i use the existing type r ecu or something else. i know this topic may have been discuss lots of times but i need exact information on what i will be coming across. i have receive alot of suggestion on how too but most of them seems clueless on what they are suggesting. i hope somebody here can give me precise direction and information on what i will be doing. maintanance on the motor such as e.g. clutch, spark plugs, belt, have been all perform. but before i drop the whole thing i need more information to minimize the error/s. thanks again for taking your time and appreciate your comment. anyone thinking of bashing this. please keep the criticism to yourself.
