Hey

I am soon going to upgrade my in jectors to 700-800cc top feed.
But I don't know if they should be high/low impedance??
The ECU I am going to use is a Apexi Power FC

Hope you can help?

i am gonna use 750cc high impedence with the power fc. gonna bypass the resistor box. if you do not want to go this route, then stay with low impedence injectors.

Okay thanks.

But was it the big difference between low/high ipedence?
Is on of them better then the other?

Low Impedance has shorter triggering time, and better idle quality.

High Impedance the drive circuit runs cooler and longer life.
