To keep this as short and concise as possible I've always wanted to build a turbo inline 5, whether it stays in the Audi it came from or I pull it for something else. Where can I find all of the specific details on all of the different types of 10v and 20v engines, like what models and years they were in, etc. I just want to learn as much as I can about all of them to make it easier to find one. Also feel free to leave suggestions like "do a 10v from x years, they are the most common and more budget-friendly."
