So I recently got my hands on some RX-7 injectors because they are almost twice the size of my stock injectors. I got them for free so no money wasted, however I was quick to find out that two of them are peak and hold while the other two are saturated. No big deal, right? Just hook two up to the resistor box and all shall be okay? Wrong. The car idles/drives like ****, I can't get it past 5k rpm and it just dumps gas into the head. Now, it would be an easy fix to just go back and put my OEM ones back in, right? Wrong, one of the studs for the fuel rail is spinning in the intake manifold! So does my car need a tune to drive past 5k rpm and smooth the idle or is it because I'm using two saturated and two peak and holds?

i dont want to be the dick but y would u think you can run bigger injectors on the same fuel map???? think about it ur sucking in the same amount of air but u r getting twice the fuel?? its comon sence u need a tune to run biger injectors and y would you want bigger ones anyways if ur not going turbo or anything like that?

Good job on half assing it. Common sense fail

Seemed like a good idea at the time. Oh well. I was planning on going turbo in the future, now I guess my next purchase is going to be a Apexi AFC NEO to try and get these injectors under control. Don't really feel like driving to a junkyard to get a MPFI intake manifold and injectors.
