just reading about different engine mods and stuff, i see that people do engine swaps, turbos, etc. in discussions and websites, they use acronyms like TT and NA, by context i think TT stands for twin-turbo, but what does NA stand for?

does anybody still upgrade their carburetor and exhaust headers anymore? or are intake kits and muffler kits the thing now?

NA = naturally aspirated (ie: no turbo or supercharger)


for the pros (proteges not professionals), intakes and exhausts are the easiest things to do. its not like a civic whereas there are tons of aftermarket part manufacterers. so with headers you need to get something custom done. custom = $$$$
