GSR or H22 injectors what is the CORRECT answer
ok i cannot seem to get a firm or a straight answer; PLZ dont reply "use search button" obviously that did work!
SCENARIO; H22A1 going into '00 Civic(EK); what injectors, ECU??
i have the H22 injectors, harness, & ECU. of course i have the EK harness. my question is this;
if i use the H22 injectors; will i need a resistor box? will the EK harness plug into injectors? what ECU do i use?
i am told to use a P28 ECU, H22 injectors, modify harness A LOT
other hand i am told to use GSR injectors, GSR ECU, and it easier, less harness modification, & no resistor box needed............
i cant seem to get this straight, could anyone please help

Re: (cmgibby)
I'm not very familiar with the h22 or what gen the a1 would be. If the engine is obd2 than no resistor box. I do know that the lude engine uses larger (320cc iirc) injectors than the tegs 240's. So I would say that rules out gsr injectors and the fuel and timming maps in the gsr ecu are going the be way off I'm sure. I did a staight engine change out on a 98 years ago and if I remember right preludes have a two peice engine harness and you car has a one peice so you cant use the h22 harness. Hopefully some one with first hand experiance with this swap will help more.

You will need to use the H22 injectors. You will need to make an engine harness by combining the civic and prelude engine harnesses. most of it will be the civic harness, but you will need to use the prelude injector clips and alternator wiring. You will also need to wire in a resistor box. For the ECU you can either get an OBD2B to OBD1 adapter harness and run a P13 ECU or a P28, P30, P72 thats been chipped. Or get an OBD2B to OBD2A adapter and run a '96 USDM prelude ECU, or a JDM '96+ Prelude ECU. Note that only the '96 USDM prelude ECU can be used if staying OBD2, all other years have an immobilzer. JDM versions don't have the immobilizer.

OK;
so get a chipped P28, use H22 injectors & get a resistor box. OBD1 ecu therefore get a jumper harness(which converts the OBD2 harness to the OBD1 ECU)
where, what is a resistor box? under the hood, near the ECU? i am just told that it is a lot of work!! i guess i was just trying to see or verify if there was a easier way

The resistor box just drops the current down so you don't fry your ECU using low impedance injectors. It is mounted under the hood, you can source one from an '88 - '91 civic. This a somewhat time consuming swap, take your time and do it right, solder your connections when making your engine harness and use shrink tubing. If done right you will never know the harness was ever modified by looking at it.

you should get a p72 or a p13 chipped so you can keep your IABs. p28s dont support IABs. you can have the IAB funtions installed on the p28 but its a bitcch.
If you look under the hood of a prelude... driver side shock tower, closest to the drive, is a box, with cooling fins, thats the resistor pack. mounted right on the shock tower.
if you have ecu questions or would like a deal on a computer thats set-up for you, lmk.
good luck!
oh, this may help too, its for an eg, but many things still apply. https://honda-tech.com/zerothread?id=650329

huh? you lost me bro
i am installing a H22 into a civc coupe '00. also what is IABs??
i will be using the D16 harness & H22 harness in order to complete swap. a jumper harness in order to use a OBD1 ECU

sry, what didnt you understand?
IAB intake air bypass aka butterflies in your intake manifold. they open and close for low and high end. short to long runners.

i currently have a P13 ECU 37820-p13-010 is #'s on it
and 4 injectors w/ 51cw or 5icw??
2 are marked w/ yellow/white
2 are marked w/ blue/white??
can this be used if i chip ECU? i still dont know about resistor box

no, you dont need a resistor box. it al depends what type of injectors you are running. I currently have an H22 in my crx and no resistor box because im using saturated injectors. Now when I upgrade to some bigger peak and hold injectors I will need a resistor box.
and for reference if you dont know what type of injectors you have just ohm them out. saturated will ohms out around 2 ohms and peak and hold should be somewhere around 10 ohms.

He has the obd1 injectors, so yes he needs a resistor pack if he chooses to use them. unless he buys 97-up injectors, then he will not have to use a resistor pack.
also i think its 4ohms saturated and 12 or 14 peak n hold for stock injectors. i could be wrong however.

ya w/ a P13 ECU i think that is OBD1
also i do beleive i found what i think is resistor box, small metal box, fins on the top, one cannon plug or QD plug on it??

most all the p13 you will see are obd1 peak n holds, however the p13 i was refering too is an obd2 ecu made in the last 6 months of 1996. it is saturated im almost sure. im using one on my H

Re: (THC07)
ok!! i have a P13 that req's to be chipped, how much? i am not sure what bolt-ons if any i will be installing. so far it will be a stock H22

Other way around: The higher resistance injectors are saturated.
(Although resistor boxes technically drive "peak and hold" injectors in a saturated fashion.)

Re: (THC07)
other than Fri & $45 i have no idea what you just said???
i can ship it you, yes, by Fri, yes. however the rest of what you say i need i dont what that is where to get it or why i need it

Meaning a quality socket (holds the chip) SST... is the type of chip used, also quality, with a H series program written on it.
