Search for those codes and you'll come up with tons of info on the differences. Tip: limit the search to the Impreza and STi engine forums.
The EJ20 can vary from 215bhp to 320+ with little or no modding, depending on what you get. Some versions have 500+hp potential with turbo and fuel upgrades, some won't do much better than 300 at the crank.
Most "JDM EJ20 swaps" if not specified are V7/V8 JDM STi motors. These are semi-closed deck, usually come with a VF30 or 34 and are the best all-around swap in terms of performance, price and potential. they are also the most commonly imported these days.
