I am about o put a 200 gsr into my 92 dx hatch. this car has never been messed with before and is 100% stock. i know that i need a odb1 ecu, but will the engine harness still work? also i heard that i need to run vtec wires from the ecu to the vtec solinoid and there might be others. anyone help with this swap would be great thanks

i put a 96 gsr engine in a 92 dx. the vtec solenoid and presure densor was already there.the engine harness plug in the shocj tower harness of the civic. i ran a chipped p28 so no need for knock sensor wire and secondary butterfly (iac if i'm right) just connect the iac with the vtec solenoid with a jumper and voila! i mixed heater hose from gsr and civic, cont remenber which one, throttle cable from gsr and all oem brackets( got the ole car so it's been easy) .

let me know if you got other question. juste keep everything from 2000 gsr and plug the harness in the civic. that's all

pK1spooled

if i use a stock edu how many things do i have to wire? and is there anyway the stock throttle cable will work or should i order a new one?

physician

don't know for the civic throttle cable, i havent try, i guess you can try it then if it not work then buy a gsr cable. if you want to run the stock gsr ecu( obd2) you will have to rewire so many things.... get yourself a 94-95 gsr ecu or a vtec obd1 like the p28 chipped to run the gsr

ok.
If your '00 GSR engine is US spec and it comes equipped with the engine harness completely intact & uncut....your in good hands. The harness is the key ingredient here. You will need to use it in place of your 92 CX harness, even tho its OBD2 spec, it's totally OBD1 backwards-compatible with a 92-95 (OBD1) vehicle. It will plug n' play to your CX's engine bay's main harnesss plugs located on the passenger side shock tower.

If your car is definitely a 1992 model, you don't need to wire in VTEC at all...its prewired from the Honda factory. Only 92 civic's had this special treat from the factory. But you will need to wire in these items:

- knock sensor (pinout D3) from the ecu plug out to the main shocktower plug.
- IAB solenoid. The black sensor box found on the underside of the GSR's intake manifold. Wire this in you want the secondary butterlies to work.

thank you for your help, i just picked up an obd1 gsr ecu today but i have a dx is the vtec prewired in that?

yup. ALL 92 non-vtec civic models come prewired w/VTEC from the factory.

Its easy to double check too.
Go look at your ecu plugs and see if you have non-empty pinouts at these locations:

A4 - VT solenoid
D6 - VTPS

Everything is pretty much hooked up but i have a few questions with a couple of hoses.



1. i cant find where to put the evap hose. can i just get rid of it? or where does it go?

2. i dont know what to do with the hose coming from the map sensor on the firewall.

3. i dont know what to connect to the sensor? on top of the intake manifold

4. i sthis clip some of the wires that i have to hook up to the ecu, its the fourth clip on the shock tower?


please help me out i am so close.

also does anyone have a link to a diagram showing the pin layout on the ecu?


thanks

the hose coming from the firewall goes to the nipple on top of the throttle body. the old map sensor is no longer used as you have the one on the throttle body now, just unplug the one on the firewall im pretty sure, otherwise your ecu will read 2 map sensors, as fas as the other plug, what does it go to on the other end??

the number one hose goes to the pcv conister and the number two hose comes from the map sensor on the firewall, so i hook the pcv hose to the map sensor on the intake mani and remove the map sensor and hose coming from the firewall?

boosted_dc2

one comes from the charcoal canister right??? that oned goes to the top of the throttle body. the other one from your old map sensor is not used anymore, you have another map sensor on your throttle body, so you dont need your old one anymore. just unplug it.

umm dood....you keep the harness that came with your car, or you will have soo much more headache.....just swap the harness from your old engine onto you new engine...then put in that ECU you have.....lot easier

pK1spooled

sorry its is coming from the canister, its the evap not pcv

he didnt have a vtec harness before so this wont work. does that car run yet???
and yes the line from the evap canister goes to the line on top of the throttle body

i havnt tried to start it i only cranked it over without the ecu in to see how it sounded, but everything is going very good right now. thanks so much for the help

boosted_dc2

just try to start it, ill bet you it starts. you wont hurt anything by trying it.

i started it up today and everything was good, but i noticed two hoses coming from the charcoal canister one says pcv and one says evap i dont know where either of them go please help me!!!also my shift linkage hits the side of the exhaust tunnel when i put it in first gear and second, is it def bent and do i need to look for a new one? if i cut a little off is this bad for the transmission at all? its that solid rod sticking off of the end hitting the side of the tunnel

what linkage are you using??? dont worry about the charcoal canister unless you have emmisions, i dont even have one on my car.

Landon

it is gsr linkage it came on the motor and i really couldnt tell you if it is bent or not, everything fit fine until i went to put it in 1st gear

boosted_dc2

it might be bent, can you take a hammer or something and bent the exhaust tunnel a little, or is it really hitting it bad.

Landon

pK1spooled

its not hitting that bad i jst wanted to make sure any modifications would not be bad for the transmission

just dont bend the linkage whatever you do.

the linkage is mint now , but i am trying to finish the wiring and i cant find the secondary intake solenoid or any wires for it, can someone help me please? and do i definetly have to switch pin a20 to a17 this doesnt make sense to me?

the secondary intake solenoid, i am assuming youre talking about the secondaries in the manifold. it is the thing that looks like a flying saucer, on the right side of the intake manifold if your looking at it from the front of the car. the iwre colors are pink/black and another color im pretty sure. you should get a helms it will help you alot.
