I have a 97 Civic Ex with a D16Y8 in it that is bad. I am looking to put the head from this engine on a D15B7 due to $$$ issues. In order to do this someone told me I am going to run into problems due to the good motor being from an OBD vehicle and the exsisting engine from an OBD 2 vehicle. What do I have to do get the good motor to work in my vehicle???
