16vt advantages of using a 20vt airbox

At the moment i have a green induction kit on my coupe, but until the turbo kick i feel it is lacking a bit low down, i read on here a month or so ago that upgrading to a 20vt airbox will give a little more low down..is this the case?

Thought the 'box was the same as a 20V's. I thought it was just the N/A models that would benefit from the swap.

that might well be the case and im getting confused!

i know what you mean bout it not doing much lower in the rev range. mine goes slow up to bout 25 and then next thing ya know your going 40 in an instant when the turbo kicks in at bout 3500rpm. thats why i think the 20vt 0-60 time is bout a second quicker. obviously its quicker but the 20vt turbo kicks in earlier. am i right in saying this?
