Which turbo should I get?

This is one of the most frequent questions asked on the site. Before you ask, do some research. Learn to understand compressor maps. Read this tech article.

Of course, all of us need some help tipping the balance one way or the other sometimes. If you can't decide on the better of two or more turbos for your mods and goals, add your question to
