Do i have a JDM or USDM engine?

Well about a year ago I had to replace the engine in my 1994 Acura Integra. I bought the engine from a junkyard with about 110,000 miles on it. So we replaced the engine, but just now noticed that the Block only says B18b. I tried doing some research and found that it could be a JDM because it doesnt have the 1 on the block. The other thing is, that I got it from an automatic. Does that matter? and if so is my engine a JDM or USDM?

Some guys like the JDM motor more because its 'JDM'... I think it has like 4 more hp or something
