you dont need the 1000cc injectors. if your upping the boost in the future then its a different story.

one of my buddies with a DRAG kit, SSAC mani makes 320whp @ 14psi. 440cc injectors, hondata, Whip Factory tuned. 100% stock JDM b18b. Whole summer, never a problem. I made 349 @10psi with my 100 % stock GSR. Custom kit built by me, R cams, skunk2 mani, and such. The tune is key, typically you can run 300-350whp on a stock bottom end b18b or b18c with no issues. Stock heads are good till they cant flow anymore CFM. Well, the VTEC ones, i know the LS ones kinda suck in the upper 300's in terms of flowing well.
