I am looking at buying a $750 very solid 1982 Audi 4000. It is running well, but is gas powered. I want something that I can convert to run on WVO (please don't yell at me for "ruining" a good engine). Assuming I source an A1 1.6 n/a engine that is 100 complete, can I just pull out the 1.7 CIS and install the 1.6? I'm aware that I will need to wire a glow plug relay and fuel solenoid shut off, but is there anything else that is different between an A1 and B1 diesel engine?
