0bd1-0bd2

[QuarterMile]

I just bought a GSR motor, it's a obd2 and the EG hatch im trying to put it into is a obd1. What all do I need to be able to do this swap right?

[HondaPower]

obd1 engine harness, fuel injectors.

[2genCRX]

like hondapower said you will need a 0bd1 vtec harness. you can use the obd2 injectors, all you need to do is file down the tabs on the plug in for the injector and it will fit the obd1 harness.

[sirtef9]

thought so, I have some mounts you can check on, I think there 94 Ls if thatd help any?

[boostedEG]

you dont need to do any of that.

an obd2 INTEGRA harness will plug right into an obd1 civic/integra chassis harness. this does not work with OBD2 civic harness'

you will still need an OBD1 P72 ecu.

if you want to change all that other shit though you will need to change the alternator in addition to the harness, injectors, distributor, etc.

[QuarterMile]

Is there some kind of adapter so that way I wont have to deal with any of that just use the adapter? J/W

[boostedEG]

an obd2 INTEGRA harness will plug right into an obd1 civic/integra chassis harness.


no adapter required. just plug it in, and plug in an OBD1 P72 and your good to go.

get the following:
-OBD1 engine harness(Not obd1 92-93 integra doesnt work trust me)
-OBD1 Alternator
-OBd1 injectors
-OBD1 DIzzy
-OBD1 ECU (p30,P72) or if you cant find a vtec one for a good price pick up a stock eg ecu so you can Drive while looking for a good deal on one!
-Integra 94+ mounts
-i would replace the timing belt,water pump,tensioner,cam seals,headgasket if i was you since the motor is already out it will be sooooo much easier

No man i would just do it the right way!


explain to me how my way is the wrong way?

[Civic-8442-]

explain to me how my way is the wrong way?

oh NO SORRY i didnt mean it like that! your way is right!
I meant as in dont getto rig it and go the cheap way! Sorry man for the confusion(BOOSTEDEG)

[Civic-8442-]

Oh sorry boostedEG i have no idea why i even wrote that! wasnt thinking!

[2pteg]

you can spend more $$ and do it civic 8442 way. that means you have to change lots of things. or you can just put it in your car the way it is and everything will plug in except for 2 sensor on the passenger side herness and work just like anyother cars. i think doing it civic 8442 is more of a ghetto riggin it.

[boostedEG]

no problem civic-8442-

i dont think either way is actually ghetto rigging it. the way i mentioned is just easier IMO.

[QuarterMile]

Will I lose any HP or anything by the two sensors being unpluged? With the check engine light show or anything like that?

[HondaPower]

Yes on CEL.

[Civic-8442-]

Engine light ON=No VTEC

[young geezer]

i have a obd 2 motor in my obd one integra and everything plugs in except for the 2 sensor. no engine lights on, no hp lost. and vtec kicked in .

[VteCrazy]

I found a adaptter on ebay that will fix this I think.

This is what I plan on buying, can anyone tell me about this.. I heard this will fix the prob. Let me know.

[boostedEG]

that harness will allow you to use your OBD1 ecu in an OBD2 car. you dont have an OBD2 car.

you have already been told how to correct your problem
1) convert the alt. dizzy, injectors, harness, etc to OBD1
or
2) simply plug your current OBD2 harness right in and start driving.

[boostedEG]

and i already emailed quartermile telling him i knew someone looking to convert their OBD1 GSR to OBD2

so you two could really help eachother out if interested.

[VteCrazy]

He already figured it out, that guy moe helped him figure it all out so everything is good now.
