Well I am building my fuel system normal stuff. I called Summit and talked them about the 30lbers for a ford, they said that the impedence was high and in our cars we use low impedence ones, and that they would only last for about 6months to a year. I am planning on using NO2, so an injector failing would mean a blown engine. So I guess my questions are will the 30lb injectors work and what model car do they come from? Are the 315cc ones, a lot of you guyes use, the FMS 30lbers or what? Also are our injectors saturated, thats what I was told? Thanks for any info, I have done some searchs on the site and found mixed answers so sorry if these are repeated, I am kinda new to this whole thin
