He said a non-ews engine will not work in my ews car without taking the accessories from the old engine, and putting them on a new one. He also said the coils did not match up, witch makes me think it might be an e30 M42 that it is being replaced with.
However, a member from another forum said that as long as it was an M42, it didnt matter weather the new engine was ews or non-ews, that it should be a direct swap without modification.
