S6 vs A8 4.2 V8 - Engine differences?

[Dan95x]

I thought the A6 4.2 block was the same as the S6 block. Just the air tumbler device and other little mods giving the extra 30 odd hp.

You might be better off posting this question in general car chat. Lots of people on this site that know lots about Audi engines that don't necessarily look in this forum.

That was what I was hoping - Definitely different engine numbers and different part numbers on ETKA - I guess that doesn't necessarily mean that they wont work, but more research needed.

Will post in general too, cheers

I bet you could swap the blocks without any issues, though.

You star - just the sort of thing I was looking for, will get my head round some of the bits in there, cheers
