can i swap in the intermediate shaft from a 1.8 8v motor into the 16v block so i can run the original distributor? or am i stuck having to source an audi 80 distributor to make this work?
You can swap the intermediate shaft to use the smaller Disti' gear but the disti' base is larger too. Best to source the Audi 80 Disti'. This is true for the 3A block. There is an adaptor ring you can use on the disti' base to fill the larger hole.
I can't verify this but i have heard rumors that this ring does not allow the disti' bushing to get oil since it blocks the oil source.
An Audi 3A is not a 16v engine but an 8v engine, no? So if you only have the short block and it has 16v pistons in it, it was converted to a 16v some where along it's life or you are using a wrong engine code. This could make a difference in your problem/project depending on exactly what engine it really is.
the block i have is a 9a (currently has 16v pistons in it) but i want to convert it to an 8v (3a specs) by swapping in a set of 3a pistons.
Got it. Just didn't understand it that way up front.

Is there something wrong or some other reason you don't just use the 9A shaft? The pistons should be easy to find used on Ebay or removed from a block at a junk yard. I now it cost a little, but you can just purchase the kit for installing a 1.8L ignition distributor in a 2.0L block. Comes with the reduction ring and new distributor gear to mate with the thinner shaft gear.
