i was looking around for aftermarket injectors for my z24 and noticed on a brand the 3100 injector was the same number and the 3.1 injector accept the last 2 digits which were the flow rating the 3.1 being 15lbs/h and the 3100 being 17lbs/h, i also noted the the stage 2 injectors for the 3.1 was the same as the stage one injectors for the 3100 has anyone ran 3100 injectors in a 3.1, would it run too rich? or have problems with the stock ecm? i have an extra set laying around and am considering putting them in..
