Confusing. I got my data from in 2013. But you are right for the link you offer for the 2003. Still, elsewhere, today, lists only "Final Drive Ratio 4.41" for the 2002 MT EX. Oddly, their AT EX FD specs also change. See:^EM2192MW

Hard to confidently decide what is true without laying hands on the actual gears from an actual car.


EDIT: the Honda site also now labels the 2001-2005 EX as a "VTEC-E" engine and the HX as a "VTEC-E lean burn." But the EX was never vtec-e as far as I know. It's just VTEC. So I think over time, as they've updated that website, Honda may have introduced errors, which would be a bummer. Getting the original hard copies of the factory service manuals would be the way to resolve it.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
