Do i use injector resistors or not?

I am going to be using Bosch 1600 top feed injectors for my secondaries. My question is do i need to use the injector reistors with this setup?

Most likely, they are low impedance injectors, so yes you have to use resistors. Just use a multimeter and measure the resistance of your new injectors vs the resistance of the old injectors.

Do a search for Damian's thread about his kgparts fuel system install. There's a pretty god explanation in there.

Assuming you're running a power fc? get the 3 ohm 5 watt resistors from www.mouserelectronics.com, based on the research a good friend has done (to include talking with an apex'i engineer who developed the power fc) those are the correct ones.

I agree with the other two posters.

On my top feed 1600 cc/min secondaries, I use resistors.

If you want to know for sure, measure the resistance of the injector.
