Wonder if there is anyone outthere who can help with my fuel injectors. I'm in the process of doing a stroker conversion on my 1991 325. Increasing the displacement to 2.9 will mean an increase injectors will be necessary. i'm trying to use a fuel measurement chart but can't get to grips with it. Algebra is not my strong point. lol. I understand that at WOT my injectors are not to exceed 80 %, as this can put added presure on my fuel pump and can effect fuel presure and flow. Will my fuel pump need upgrading as well ??
