Aiming for 10psi

By the looks of the spool thread I should be exspecting 5-6psi in the 3500ish rpm range, and 10 around 4k?

 

get a .48 hotside
I dont think you will make your spool goals on a .63

 

thats pretty much the exact turbo I am about to be running for my setup. Will be a tad more laggy than the .48, but have more power per psi due to less backpressure. Will be interesting to see how it works out because i too have received the same criticism, but nobody runs a .63 t3 hotside that I know of. Should be similar to Hustler's spool with his .86 t2 hotside.

 

I suspect you'll make 10psi by 4K even with that .63 A/R housing....

 

With a good MBC it will be at full boost by 4k easy. If you got a snazzy dual port diaphragm for the wasteagate you could knock a few hundred RPMs off of that too.
