Default Are 310 injectors too small for this 2.0L, ported head, 12.5+ compression??

I got a big time deal on a resleeve GSR block and ported head job and gonna go with 12.5+ compression.

Ive been running Toda b cams in my b16 and time to get this thing moving.

Here is the setup im going with. The cams and boltons are already on the b16.

Ported head with 5 angle
Toda b cams with Toda valvetrain and cam gears
Bored 70-65mm ITR TB
AEBS manifold
KOS 4-1 header with 2.5" collector, 2.5" exhaust
Regulator
255 pump
CM stage 3 clutch
8 pound fly
RC 310 injectors

84 or 85mm on the sleeved GSR block
Endyne Rollerwave pistons
eagle rods
new bearings, seals, gaskets, pump

either GSR or LS crank i need
I already have a p28 with custom toda program and vafc

Are the RC 310 injectors from my existing setup too small for this setup?

Im hoping to crack 220+ from this setup, but dont wanna high expectations.

thanks for any advice

every motor is different, you will know about the injector size when you dyno the car and check the air/fuel ratios v/s the fuel press, just an opinion but if you are above 55psi then you need to step up to 370cc injectors... just my .02

ok, thats perfect because, i do have a wideband in the car, a custom program (thanks to CHEETAH ) and vafc. my plan would be to break the motor in before going to the dyno, and ill get a perfect idea of where ill be at with the 310 injectors.

so yeah, i guess i coulda answered my question. i am gonna start around 42 psi and try to keep the vafc at 0%.

Im might go hondata when comes time for the dyno.
