im doing my second h2b setup and im wondering will i have to use a resistor box with a obd1 gsr harness. im using stock h22 injectors. my last setup i used a h22 harness wit the resistor box on it, jw if ima have to use one again,

any help is apreciated
thanks

 

It depends on what year h22 injectors your using. Iirc the obd1 injectors require a resistor box while the obd2 ones doesn't.

 

if your using stock stock injectors yes you will. If you use aftermarket saturated injectors you willnt need a resistor box

 

Yes I'm using obd1 injectors from a 93 h22, what do yall recommend to do use a Gsr harness and add a resistor box or try and find a obd1 h22 harness with it already

 

you can use either as long as u install a resistor box. if you can find an h22 use and just trim what you dont need otherwise just add it. there are plenty of threads on here of how to make them

 

thanks alot

 

majority all obd1 h22 came with saturated injector ... i ask the same question and pplz told me i need one i took mine injector to honda they told me they were saturated so i dnt need an resitor box............just check your injector to see if there peak and hold or saturated

 

how can i find that out? they are just stock h22 injectors

 

Correction All OBD1 H22 injectors are peak and hold which means they need a resistor box (low impedence=peak and hold) All OBD1/2 Civics, OBD2 Preludes/Accords, 94-01 Integra and so on are saturated (high impedence=saturated)

To check the injector to see this, use an ohmmeter. When you ohm them out, they will have i believe 2 ohms or less (hence, low impedence, peak and hold so the resistor box adds around an estimated 10 ohms more or less) if they were saturated their resistance will be much higher, like around 11.6 or so. If its from an OBD1 injector from an H22 it will be low and therefore you'll need a resistor box/inline resistors

 

my stock h22 injector were around 11ohms and it came out of a 92-96 obd1 prelude and my boy jdm h22 obd1 92-96 as well were saturated

 

Must have gotten them mixed up with some other injector because NO Prelude injector from 92-95 was saturated (peak and hold injectors require a resistor box, thats why Accords and Preludes within these years have resistor boxes). The 96 crossed over to OBD2 and they are saturated.

 

i ordered a h22 from hmotors. i asked for a obd1 motor. turns out the motor is a 97 but everything is obd1. after some research i found out that accord sir's were obd1 up to 97 then switched over either mid year 97 or 98. so would i have peak and hold injectors or saturated?

 

so if i wanted to remove the resistor box i would have to get obd2 h22 injectors which dont require one which are high impedence?

 

Correct. Those injectors flow 290cc

 

kewl thanx, yea i think ima just wire a resistor box, obd1 injectors are 3something cc

 

The OBD1 injectors are 345cc

 

use a multimeter to check the ohms on the injectors

if its less then 5 ohms you will need a resistor box

if its 10 ohms or higher you will not need a resistor box

 

Already told him this
