single turbo converstion?

has anyone heard of or done a single turbo converstion to a vr-4?if so is it more powerful or not?

Why would you want to switch from 2 to one?

I wanted to just see if there is one or if they make more power

Think about it this way, if you have two turbos pushing boost into your engine, don't you think that one would be less powerful? I wouldn't even think about going from twin turbos to just one. It's like throwing away money to make less power
