We just had a thread with a large discussion on feed and drain sizes for holsets.
Everyone here who has a holset apparently runs a 4an unrestriced for the inlet although I think that is too much oil.
I run a 3an on my turbo, but it is not a Holset so the choice is yours! (obviously), but read up on it but stay above 3an for journal bearing.
a 10-12AN drain should be enough to drain a turbo with a 4an feed, and you can probably go 8-10an drain with a 3an feed, although people tend to stay away from drains smaller than 10an with the larger turbos.
