Default Twin turbo size

Im thinking about getting twins soon and was wondering what sizes would be right for what I have. I was thinking a s300 over a s480.

The 62/65/12 over a 475 works really well as a dd. Spools quick. I would recommend that you port out the wastegate on the secondary, or an egate works even better. X2 on the lift pump and fp gauge. Some 024 DVs would work well for ya too.
