the nitrous kit already adds more fuel pressure by running nitrous pressure across the FPR which is jetted at a certain level...........



and yes you can also add more fuel by the FPR........


its as simple as more pressure......... kinda like the differnce between 10 psi or 20psi from a turbo using the same tubing, at 20 psi there is alot more air.........

19lb injectors will fail at about 90psi........... about the safest you'd want to run them would be 50-70ish..........


just buy a sr20det or a b16zx9r-LMNOP
