Dear community, I am terribly sorry if I address an already existing topic, but after 1 1/2 hours I have just searched 140 of the 1394 pages and so far not found nearly something similar. Therefore my question: Can I install the ADR engine in an Audi 80 B4 Limo or Avant, which is also in the convertible? Suppose I have the 2.0E ABK and would like to put the 1.8 ADR or AEB & Co. in from the B5, does that fit? I am looking for a cheap winter car and have a budget of 4000€. However, since I like the B4 quite well and have known it as a good car, I would prefer to buy one of these and possibly plant a more economical/stronger engine. Ask for constructive contributions. Thank you in advance! Greetings, Oldenway
