Quick question
 

I just need to know if I can swap an 04 Allroad 2.7 engine into my 04 A6 s-line 2.7 without swapping any parts, and if not what parts need swapped?

I bought my a6 about 2 months ago and it jumped timing the day I picked it up (literally drove it about an hour and didn't even get to rod on it!) Once I pulled the heads I decided a new (used) engine would be cheaper and easier than a rebuild.

Another question is what would I have to swap in order to put in an apb engine?
