Vitz Rs turbo vs U.S. Yaris add turbo?

[weaponrcamry]

Since japan or the foreign states have the Vitz turbo, and some countries have the regular yaris or so, what would be the difference of adding a turbo to our yaris? Wouldnt you think that it will give you the same performance as the vitz turbo? I think it will. I was thinking about a 2zz swap, but then I remembered that you cannot add a turbo into the engine bay, just wouldnt fit. And I believe the 1zz would be the same way. They both have strong aftermaket support.
