It's actually my bf's A4. I'm just trying to get the instructions for him because I have more time on my hands to peruse the boards.

A while back he came across a guy who had an entire S4 to part out (he knew a guy who worked for a car insurance company and got it cheap.) So my bf was able to buy most of the stuff he needed to do the swap (I think the only things he's missing are pedals?), so the donor car thing isn't a problem. He's had everything he needs sitting in a garage for months now.

The person who's actually going to do the swap is his brother who has a mechanic shop that specializes in performance. But my bf isn't sure if his brother can do it, so he wanted to get the how-to instructions just in case.
