The simplest fit would be one from a 2005 or 2006 US CR-V.
There are a bunch of them for sale on eBay. I personally would avoid JDM engines, which stands for Japanese Domestic Market. While they would physically fit, my understanding is the JDM engines don't have all of the same engine sensors, so there's extra things you have to do to trick your ECU into not throwing errors.
