So I am in the process of converting my 05 STi to run e85. I am looking to convert my side feed injectors to top feed to assist with the idle and tune. Have heard enough horror stories on big side feed injectors and want to stick to what my tuner is good content with.
With that said, I am looking to do a fuel rail conversion kit of some sort but what I am struggling with is do I need to upgrade the fuel lines as well and are their pros and cons with going with high vs. low impedance injectors? I know P&Ls kit has the resistor box for the low imp. injectors so that is not my concern, but did not know if there was an easier way (cheaper) to just converting the rails and not messing with the fuel lines.
Please let me know your thoughts. I appreciate your help!
