This has been itching at me for a LONG time on these forums haha. yes i realize its a 10 year old thread...better than starting a new one!
I have been on 10+ car forums and every single one i have been on has explained N/A as Naturally Aspirated, not Normally...I read through the posts above and it just made me more confident in posting this haha.
It would make sense for the administration to change this, as it makes more sense. Normally aspirated refers to a common engine configuration in a given car, Naturally aspirated refers to the fact that the engine you are talking about is all engine, no turbo, supercharger, ect.
just had to get it off my chest!
