I was running 330's on my NT with a S16G, so I thinking no, but every car is different.

you will max out the 450s easily with that turbo.

You need 550s at minimum.

If you have DSMlink or a chipped eprom then i'd go even bigger so you aren't buying a new set of injectors when you grow tired of the 16g and go bigger... which you will, we all do.
