Hello, I'm going to start off with I'm an all chevy guy and Im really new to the whole Honda thing. I have a 97 Integra that is all stock in the engine bay it has a b18b engine. A friend of mine is giving me his old b16 head which version of the b16 it is I won't know until I get the head ethier today or tomorrow. I have a feeling it's an obd0 engine. I also have another friend that is giving me a b18c1 block I think that model is right it's out of a 98 gsr, so I know that the block is obd2. I know that the block will work in my car but I'm lost with the b16 head, if it's an obd0 or obd1 how much will I have to modifiy my wiring to work with the older style set up, or is it even worth it. Any help for this newb would be great.
