Just what exactly is different in the engine on the 350z from maximas and altimas that is making it crank out more hp?! what exactly is it? anyone know the answer? and what is different in the maxi engine from the altima engine?? or the infinity model........ Someone have the stats and data from nissan, like their blueprints or something to that effect? Aren't all of you curious?

 

Exhaust and Intake are 2 things that crank more horsepower from the different cars. There are more but I don't know them so wait til an expert replies to this thread.
