Well, there's no formal definition, but the 2004-2005 was mostly the gearing change and a slight change in engine performance, but there were literally hundreds of detail changes that improve fit, finish, and reliability between 2003-2004 - believe me, I did the research before deciding that 2004 had enough of the teething problems (power steering pump overheating, steering column clicking, windshield stress cracking, etc.) with the initial production solved to take the risk. I've never heard of anyone calling the 2005 changes a new "generation". Generally, people think of the 2002-2006 cars as Gen1, and the new 2007- and beyond (with the turbo motor) as Gen2.

Officially the R53 is 2002-2006, however 2004 had no major changes. 2005 & 2006 were the only big changes as I mentioned, like the taller gearing and available LSD, and more HP. 2004 had only the standard production fixes, nothing substantial. I'm not sure why you think 2004 had the big changes. If you have a 2004, you have the original short gearing and less HP, and did not have the option of the LSD available like in my 2005.
