A 16G w/a good tune will have better top end, hold boost better to redline, and more useable power (area under the curve) than almost any VF series turbo. As said earlier the VF series turbos are not rebuildable.
(to answer your earlier question) yes a 16G is still fairly small, while still being a good step up from the stock TD04. Also, Blouch will do an EVO3 16G with an 8cm exhaust side, just call and ask.
FYI: I have a Blouch TD05H-18G 8cm on my EJ257 2.5L hybrid build and I love it. I has an amazing powerband and makes 300whp all the way until 7000rpm (even though I am only running a conservative tune of 16PSI). IMHO the perfect DDer turbo for the 2.0L is a EV03 16G 7cm, but for the 2.5L it is a TD05-18G 8cm (with the larger TD06 compressor cover of course).
