Can anyone tell me the difference between a 16G, big 16G,evo 3 big 16g, and T04b? Thanks

 

You are going up in CFMs with those turbos in that order (except for the T04B, because that's naming the three different 16Gs as all the same). The T04Bs from what I understand is oldschool tech...someone correct me if I'm wrong.

 

so the bigger the turbo the more HP and more supporting mods... thanks

 

pretty much.. Your not really looking at a huge difference.. The 16G and the evo 3 big 16g are gonna be different.. But you are going to need the same supporting mods with each one.. Unless you don't plan on running more boost to them, which in that case doesnt really make much sense to upgrade to them...
