I bought this 98 civic 'SI' turbo. I don't know much about it but this car has a lot going on. I'm trying to learn what I can about it especially because I have a check engine light now. I just talked to the guy that I bought it from. I guess I have a honda civic si ecu with a chip in it for the turbo. He also said its also converted to OBD1? So now i gotta look into jumpering some wires and counting the flashes of the check engine light or something.
