It depends on what injectors you get. You can get some larger injectors that will slide into the OE fuel rail. And, depending on the age/use of your current fuel pump, it may be sufficient enough.... Otherwise, get a Walbro 255 lph kit...

throwing in more gas won't make it any faster. It'll make you have more trips to the gas station.
You'll need a 300zx fuel filter, 300zx/walbroro fuel pump, some way to control it, and perhaps a z32 maf.

First off what's this going on? KA-T, SR, CA?
To answer your question bigger injectors aren't your biggest bottleneck. The stock pump sucks and can't handle stock boost on any turbo Nissan motor. It should be first, with some kind of adjustable fuel pressure regulator. If you're looking to get more fuel from that setup, get some type of piggy-back fuel computer. After you run out of fuel using that system, then you search for bigger injectors.
