I agree with some of what you are saying. Still would like to know what OP wants. We are both guessing on what numbers he wants to make. As for the graph you posted. That is a pretty good power curve. Would like to see it in RPM instead of speed. Also, that is a D16 not D15, makes a difference and if we are talking 400whp that is another 95whp and that is about 7-9psi more boost and that is putting that setup over 30psi. A ebay t3/t4 is not effecient that high.
The bisi cam will help and is a good choice.
As for 60 trim. I did not suggest the S372 but yes you can get it in 60 trim. Here is an example from Garrett turbos.

I am not here to fight about it I just want people to get correct information. You cant say that the 63 trim of the 28 is better then the 56 trim of the 47. If you were to call Garrett and say "I would like to order a 60 trim turbo" they will just laugh at you.
