550 injectors on stock fuel pump?

question,
will rx7 550 injectors work with my 03's stock fuelpump or do i need to upgrade to a walbro 225ph or something like that

they are fine as long as you have something to control them.

the fuel pump simply delivers fuel, you porbably have enough for 300rwhp.

Good for about 300 RWHP max, assuming the 03 pump is like the 99 pump.
