The goal for my car is 450whp. I have most of it planned out now except for the fuel system. I'm was planning on getting the lexus AFM and 550's but I don't know if those will flow enough. I'll already be getting some piggyback, most likely an e-manage, so tuning is available. What fuel system do you think I should run? Including, pump, reg, fuel pressure and injectors. Should I replace the fuel rail? I could figure this out but I'd rather ask someone with experience who knows the weaknesses of the stock system. I know I could boost the pressure up and make the 550s work but this is my only car and truly a daily driver. I don't want to blow anything. I'd rather spend some extra cash than do this twice.
Max power on 550's

The stock rail is fine. Get one of the adjustable fpr & dampner removal line kits, and a walbro pump and you'll be fine. 550's would be ok for 450, go bigger if you want more insurance. You might run into tuning problems with bigger injectors if you run the lexus afm - adjusting the fuel will shift the timing on the stock ecu. Also idle may suffer.
wicked awesome, thanks for the help. I tried some calculators and equations, but real world wins every time.
Turbo Drifter made 435 rwhp on 440's, but we ran out of fuel at that point, we couldnt get it any richer. 550's should be fine for 500 rwhp.
