I am installing a obd-0 B18a into my 1992 hatch as I am getting a really good deal. What all do I need to change on the engine? I know I have to change dist. but can't you just rewire the obd-0 dist to work? If so, how? and What about inectors? Hasport says you can use the stock DX ones. Is that going to cause any harm? All help is appreciated.
