i found some rc 550 injectors for an H and B series for a good price, will these work with the f22b1 vtec?

 

i believe so. the h22 uses peak and hold injectors so as long as you car has peak and hold injectors you will be fine.

what are you going to tune the motor on?

 

I'm gonna be using Crome or Hondata

 

just as long as you have something to tune you are good. what year is your accord?

 

It's a 91 exr

 

What impedance are they? If they are saturated, aka High impedance (12-13 Ohms) you will need to remove your Resistor box. Not all H series engines use the Peak & Hold, aka low impedance (2-3 Ohm) injectors. The 97+ H22 use high impedance injectors.

Just make sure you know impedance the injectors are that you are buying before you throw them into your system.

 

ok thanks, when i get either crome or hondata am i going to need my resister box still? will there be a setting for high/low impedance?

 

The software you use, be it Crome or Hondata, doesn't dictate whether or not you use a resistor box or not. The impedance of the injectors themselves will tell you that.

Saturated/High Impedance (12-13Ohms) = No resistor box
Peak & Hold/Low Impedance (2.5-3 Ohms) = Resistor box
