New Engine for 92 Integra

I have a 92 Integra that I really need a new engine for. Regardless of price, but the lower the better, what should i get for a top performance engine? I was looking at spoon engines but then was told not to so what would be the best? Also, can you give me links to where I could find to buy the engine and/or to look at some? Thanks..
