Cool i have a boosted D16Y7 too. I got stock internals running 7psi now.
Getting ready to install my Y8 Ported Manifold,450cc DSM injectos, and being Tuned by Hondata. Should be able to run 10-12psi easily.
I sugguest you get a Hondata 3B system. You can find them for cheap on Honda-Tech.com
Also upgraded Injectos would help too.
