Really, which B16 turbo are you talking about, and which zetec turbo?

From what I have seen, they dont lack torque at all, a bar of boost on a B16 gives around 300lbft of torque, which is apporaching 200lbft per litre, much better than most zetec or YB engines for the same boost.

Or do you mean that a high boost 2.0 engine gives more torque than a 1.6 low boost one, cause if so I would say that oranges are definately more orangey than apples
