What would be the best engine to buy for a late model Honda Civic?

I'm looking to start my first build. I want the best engine for the price. I'm not rich. With all the types of engine swaps I can do, it's hard to pick when I'm new to this and so many people have different views online. Any ideas will be great.

GM, Ford and Dodge sell crate V8 engines.

One of the meanest machines I've ever seen was a 2001 s2000 that someone had swapped in a 2006 viper v10 into. It was bad *** and fast as hell
