on 2000 up cars, injectors will need upgraded at ~400RWHP naturally aspirated. don't even think about not changing something by going forced induction.
you will need a racetronix PnP kit (255 Lph pump) WITH WIRING harness above 450RWHP naturally aspirated ??
forced induction you will want to go with a fuel pressure regulator at the rails & probably 42# or larger injectors above ~500RWHP

I ran 42# injectors naturally aspirated for the longest time, even ran them boosted. I just recently ran into not having enough fuel pump to hold what I have.

So when he dynoed tuned it I ran out of fuel pressure at around 5,000 rpm. I did have 42 lb. injectors but the stock fuel system died at 5,000 rpm.
So I immediately ordered a Racetronix system from harness to pump, everything. I think back in 2002 it cost like $275.00. Then I was good to go. GREAT system.
You will be set up with a Racetronix for what you want with a ton of growing room up to around 600+ RWHP.

My 1998 had everything you see in my sig installed at the same time. But one thing I forgot about and my installer just forgot to ask about......a new fuel system.
