Will exhaust and WG ports on 16g match up with o2 elim. exhaust?

[GSXpower]

I am planning on getting a 3" O2 eliminator turbo back exhaust from RnR, and I am going to upgrade to a big 16g in the future. What I want to know is, are the exhaust and wastegate passages from the 16g turbo the same size as a 14b? And, will they match up to the 3" o2 eliminator DP? I would like to get the ported 16g, but I am afraid that the ports won't match up to the new 3" exhaust I am planning on getting, I don't even know for sure if the non-ported 16g will match up. This may be a novice question, but I haven't really been able to get a straight answer, and I am going to be spending the $$, so I want it to be right. Thanks for any help.

Alright thanks guys, That is what I thought, but the devil is in the smallest details, and I don't like finding surprises when I am trying to put it all together.
