    2.8 Stroker Injectors

    Will i need bigger injectors or can i just get away with an adjustable fuel pressure regulator (and crank it up).

    SETA stroker?? if so.... makes me sad... if your running the stock fuel pump... the m50 17lb injectors will make your fuel pump breathe better. but with an adjustable regulator. if u "crank it up" u should probably put something a little bigger in.

      A 2.8 stroker is not the same as a Super Eta 2.7i engine.

      OP for the 2.8 I'd recommend 19lb injectors and adjustable FPR.

        Also, stock fuel pumps are just fine. My turbo E30 has a stock fuel pump. :)

          Idk if an AFPR is necessary, but 19lb/hr injectors are what I would use.

            leave the FPR alone. just change the injectors and get a tune for it.

              No need for the afpr. The stock fuel pressure will feed the 19lb injectors just fine. I dont care how much bigger your bottom end is. You wont need more fuel pressure. Its not FI so you shouldn't need THAT much more fuel.

                  M50 injectors are plenty big enough for any M20
