EK... EG.. etc are generation years.....EK are hondas from 1996-2000(6th gen)... EG are from 1992-1995(5th gen).....i have an 2002...thats a 7th generation...2001-2005..... Just remember due to emission/OBD laws in like 45 out of 50 states, you cant swap an older engine into a newer car... since Honda stopped making the B series in 2001... and my car is an 02...i have to go K series which is better anyway... so if you buy an older gen... you can put whatever motor you want in it...
