my question is. Im doing a 400+ whp ls/vtec this winter and im takeing the injectors of my turbo D16Y7 (550ccs). will the 550's be enough or should i get something a little bit bigger for the build?

Use this:

***(cc if injector) x 4 (cyl) = ****cc
Take that ****cc / 6 (cc per whp) = ***(whp)

Ex:

550cc x 4(cyl) = 2200cc
2200cc / 6 (cc per whp) = 366.6 whp

These measurements are based on a 75 - 85% duty cycle. for 400+ whp, I'd say go 750's or higher to give yourself a window, should you up whp in the future.
