ok im thinking about droping my h22 turboed in my civic and im wondering how i would go about hooking up the resistor box for the injectors ? and im not sure what i will need the car currently has a ls swap in it and im not sure if i would still use the si rear t bracker and side top post bracket?[i know i need the mount kit]. the h22 is in a 97 accord which is set up like obd1 with the side connectors in the engine bay but is obd2 inside car to ecu and is wired up for obd1 dizzy. so would it be easier to pull the wireharness out of the accord and use it sinces its ready for the h22 or use the 97 ex harness and wire up a resistor box and wire up for a obd1 dizzy. thanks for all the info ahead of time

You can make your own plug and play plug harness to wire in a resistor box without cutting or splicing or cutting into your harness at all. I highly recommend this look here: https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/complete-diy-plug-play-obd2-civic-resistor-box-write-up-ej6-ej7-ej8-em1-eg1-eg2-eh6-2073540/ . the dizzy im sure u can buy a obd2-obd1 conversion harness to run the dizzy that's on the motor for like 35 bux at rywire.com. USE THE HARNESS THATS IN THE CAR it makes things much simpler and run from there. jumper harness for a chipped p28 to run the h22 and u should be good to go as long as u have bought all the mounts and stuff to do this.

i have a jumper harness for obd2 to obd1 and chipped p28. ok so that sums that up any1 know bout the brackets

If the engine is already OBD2 you dont need a resistor box. I have an OBD2 H23a vtec in my civic no resistor box. OBD2 injectors are Saturated and dont require a resistor box. OBD1 H22 are Peak and Hold Injectors You need a resistor box or you will burn up your ecu. Check he plugs on top of the Injectors the OBD2 plugs are Black, The OBD1 are gray. good luck with your swap.

i have precision 1000 cc injectors like listed the cars fully built turboed i have to have a resistor box.

You said you were droping an H22 Turbo engine into your ride, It didn't say anything about what Injector you were using. Just tring to help.

h22accord101

yea i know and i appreciate your help man. but idk if you know anything bout turbo cars but any turbo car doesnt use stock injectors they dnt preduce enough fuel. but there r sum injector that dont require resistor boxs but i have to run 1000cc injectors which require resistor box and i dont wanna wire them in to the injector wires i think dude above has the best ideal but i appreciate your help cause if it was stock i wouldnt have knew you didnt have to have one

everything is over complicated in this thread,

If you are installing this in a civic, use the civic harness and use the alternator wires form the prelude/accord harness. the civic alternator wires are too short. Depin the wires and match accordingly. do not cut unless you are wiling to solder properly and heatshrink. use your CIVIC injectors and your CIVIC fuel line. you will need to flip the fuel line to work properly (the side that is connected to the filter will need to be on the h22 rail). the civic harness will plug into the injectors and into the shocktower plugs/ecu (depending on ef/eg/ek).

ok the car is turboed and has 1000cc injectors like ive said i am not using stock injectors. and as i also satted its in a 97 civic which is a ek and i will have to extended alternator line only thing i needed to know was about the resistor box and the guy up top clarified that for me.

thanks for every1s help

im currently starting the same swap will the civic injectors provide enough fuel for the h22?

h22accord101

i wouldnt think it would if it was me try and find a set of obd2 h22 injectors and use them if it was me. and guy above stated the obd2 h22 injectors dnt need a resistor box so itll be enough fuel and match motor

not to thread jack, but stock civic injectors will not supply a bigger motor and a turbo. you will need atleast 440 injectors. civics range from 190 to 220.

i would advise against h22 injectors. they are 240 injectors. Forget resistor boxes on the original motors.

if you are installing these in a civic, order injectors for a civic. the injectors are interchangeable. just be sure to order the proper size for current or future power goals.

hey be my guest man the more advise for some1 the best i dont know everything bout hondas but ive worked on alot of them boosted and na

austin.sin.slmr

I have the greddy kit off of my d16 that i will end up modding to work the h22 i only am looking at 7lbs - 10lbs of boost, what size injectors would you advise? i dont want to do anything real crazy with her i drive 45 min each way for work daily...
and also any ideas power wise what some thing like that with a auto would create?? im hoping to still get some short of decent mpg out of it lol

440's/450's.

cool thanks guys

xero_xero

for 450hp (expected) you would need at least 900s
for 300hp you would need 600s

this is based on your hp numbers along with the duty cycle of the injector. you should never surpass 80% duty cycle on an injector. so if you have 1000s. expect them to run 800cc/min max.

link to the calc.

Engine Horse Power - put your number in
BSFC (.50 for n/a) (.60 for super/turbo)
Number of Injectors (4 for h22)
Max Duty Cycle (always .8)(stops you from overworking your inectors)
Fuel Pressure (43.5 unless you have an aftermarket regulator)
