2G Which injectors to use?

[dsmAB]

I'm going to get an evo 3 16g in my car soon, and i'm shopping around for fuel right now. Most likely i will be using dsmlink to tune so i know size of the injector does not really matter. But budget-wise, I just got a really good deal on a set of evo 9 injectors but i was thinking it might not be enough. The best pump gas we got here in edmonton is 91 . I'm shooting for about 20psi of boost on the e316g.
Is the evo 9 injectors sufficient for running 20psi on 91 pump??

Denso 660's can be had for around $100 used if not cheaper. If I'm not mistaken, that's 1/4 the price of FIC 750's and I'll bet they flow nearly the same at stock fuel pressure.

I'm sure 660's could handle 20+ psi on an Evo3. Evo 8 & 9 run around 15 from the factory on a fairly high flowing turbo.
