Default Wastegate Size?

Well guys, building a small motor moderate boost setup. pretty much a 5.3 w/ tc78

Low boost will be 10psi, and up to about 20Psi.

Now, for wastegate size, would a 38mm be ample, or should I step up to a 44?

I found a good deal on a deltagate 2, but, cannot find any specs about spring sizing, etc

thx guys, I talked to josh@KTYP and he recommended a JGS 40. I will either go with that, or a precision 46

Stepping it up to a 44 sounds good. Bigger is always better when you have concerns about controlling boost.
