Quick question, I'm about to buy new injectors for my build from RC and am not sure which style and impedance the FC TII used. I tried searching but found a few competing answers. So I'm planning on running 750cc primaries and 1200cc secondaries. I need to know if I need P&H injectors or saturated, also bosch or denso style. Any help would be much appreciated. Thanks.

 

Your question is specific about the impedance of the injectors you need? S4 Early is Low Impedance (with a resistor pack), S4 Late is High Impedance, S5 is High Impedance.

Take a multimeter to your current injectors and measure impedance between the terminals. 8 ohms or less is low impedance, over 10 ohms is high impedance.

Stock TII injectors are 550cc.

You will need Denso style tops in peak and hold. As far as high or low impedance if you're running a standalone it need not apply, if not the member above me that commented is spot on. I run a similar setup fuel wise the only difference being 1000cc secondaries, which should net around 350whp(I don't specifically recall the exact number from when I did the fuel calculations).

 

Cool, I just ordered RC peak and hold injectors. Thanks for the help guys.
