 Hey cool, thanks for doing this thread :)

I have a question. I have a 1990 Audi Coupe Quattro, with an engine that isn't so healthy.

What 5 cylinder Audi's are potential donor cars? Googling has brought me nothing but confusion.


Thanks!

 I have an Audi question!
I need a rebuilt or used cylinder head for my '90 Coupe Quattro. I cannot for the life of me find either:

1. A good source for used Audi parts that isn't ebay.

2. Info on which other 5 cylinder Audis I could get a compatible head from.

Any help would be really really really appreciated. :)

car-part.com might be able to find a junkyard local to you that has what you're looking for, though you are going to deal with a half dozen different gruff mechanics who have different insane pricing schemes all over North America.

Yeah I was bracing for that. My 944s have spoiled me. (:psyduck:)

My guess is that this is the 20v I5 which would be a 7A engine in nonturbo form.

The AAN engine is 10v, so you don't want anything from that. I think the bottom end is supposed to be interchangeable between those two engines, so it's something to look out for.

edit: As far as I can tell the AAN engine was in the Audi 4000 and 5000, and the 7A was in the Audi 90 and Coupe/Coupe GT/Coupe Quattro. I don't know about the Audi 100, but I think that had an engine that was neither AAN nor 7A. Audi 90s should be plentiful, but they also came with the "NG" engine, which appears to be a 10v, so make sure.

The obvious way to tell the difference between the 10v and 20v heads is to count the number of valves. ;)

Yeah it is the 2.3 7A. Thanks, that actually helps a lot. Coming from pretty much exclusively working on 944s, I wasn't sure if there were different water passages or not... stuff like that.

More and more its looking like an AAN swap would be the easy way out. e: easy does not equal cheap :(
