Yes, I have some experience with the Audi 5 in a Vanagon. They are strong and durable engines in the heavy vehicles they came in and I have 18 months and 18k miles on the 2.2 version in my 87 Syncro Camper. I have had no problems so far. They are basically the 4 cylinder engine with an extra cylinder on the end and some mechanical improvements. They share the bore and stroke but the extra cylinder makes them 25% larger, more powerful, and smoother. The engine compartment of the Vanagon was designed with the inline 4 in mind (diesel version) so they can be installed readily with mostly factory parts. The 5 cylinder is longer so it is a tighter fit. This adds to the cost and difficulty of the conversion but the result is worth it to me. Most of the 18k miles have been done fully loaded for camping and towing a small boat trailer of 800-900 lbs. The low end torque of the 5 cylinder makes this towing comfortable, not the white knuckle experience it sometimes was with the stock waterboxer. Highway passing is possible even loaded like this where before I was often stuck behind slow moving vehicles unless there were long clear openings ahead. We now arrive at distant Baja camping/fishing spots faster and less frazzled. My Syncro has been transformed. I plan to keep this thing a very long time. And yes, it is smog legal in California.
