I'm looking at a ob0 motor to swap into a blown up civic i have and wondering what all will i run into when swapping between them. I have done a swap like this one but i went from ob2 to ob1 and wasn't that hard just swapped the coolant tube and swap the bolt on stuff.....so what I'm curious about is the ob2 has a knock sensor(?) i guess that's what it is that has a plug but the ob1 was in the distributor....so please if you know what im going to be looking at great...i would like some input. thanks
