Proper turbo size for m20b25...

my goal is 275-300hp.
ideally I'd like to start spooling at roughly 3K.

I have the opportunity to pick up a brand new turbo (which would save alot of the cost of buildup.)

here are the specs;

Garrett t3/t4 turbo
t04B housing .60 .63 exhaust, stage 1.5 wheel, got the smaller gt30 5 bolt for better fitment

I understand there many other factors to be considered her (mani-fab) etc.

i'm still not completely onboard with knowing how to match turbo sizes to engine sizes.

I have a healthy m20b25.
