I'm looking to get into a faster car with more potential then the one I currently own (300zx automatic non turbo)

I was wondering if someone could tell me the HP and TQ ratings for the last several years.. what are the main differences between the Ej25, Ej22, and Ej18, and what years were they used in the 2.5 RS?

Also, how fast would a stock automatic 2.5 RS run in the 1/4 mile for each of those generations? Whats the potential for automatic RS's? Thanks for the help!
