So,
turbo cars have a 3bar fpr. You can EASILY put in a 4bar. Does the stock pump flow enough to support the 4bar? Isn't that just as good as upgrading the injectors?

Now i do have browntops and a 4bar, will the stock pump flow enough in that case?
 
stock will flow fine with a 4 bar

figure with a 3 bar while running 20psi boost you are pushing the same amount as fuel pressure as the 4 bar @ 10psi ... either way most have run the 4 bar @ 20psi just fine so
