  • High Volume Pump & 24LB injectors for NA?

    How would 24lb injectors and a high volume pump affect a NA 3.4L? I'm in the process of rebuilding my 3.4 and I'm going to upgrade to 24lb injectors a high volume pump for the turbo later on. I won't be getting the turbo until fall/winter (or second FFF GP) but I would like to atleast put the new injectors in while I have the engine apart. Will the new pump cause me to run rich?? If so I also purchased an adjustable fuel pressure regulator to have better control of A/F. Question is though should I install the new injectors and wait on the pump, or install both at the same time??

    Pump won't change air/fuel. But the injectors will. You will run way richer.

      24 is probably too big for NA application.

          With your mods it looks like you don't need eather one.
          Those injectors will only hurt you.
          For now it would be a waste of you time and money.
          If you want more fuel get an ajustable fuel pressure reg. End result is the same as biger injectors but more use full.

            I'm in the process of rebuilding my engine so my list of mods isn't up to date. Anyway I've decided to go with 19lb injectors for now and then 24lb when I get the turbo.

              That sounds kinda like a waste of money. Why not wait and just buy the 24lbs, that's just throwing money away I think... [img]graemlins/stickpoke.gif[/img]
