I currently have a 94 eg hatch with a 96 b18b1 in it. It is OBD2. I also have a problem...its fucked. I acquired a b18b1 from 1994 for free. If I swap it out for the 94 what will i have to change, seeing as how it already has a 96 b18b1. What will have to be converted over from OBD2 to OBD1? also will the 96 valve cover fit the 94 with no problems? any help is appreciated. thanks.
