my question is that, would a jdm itr engine bolt up and plug and play in a 92 civic, considering i got the complete clip. i have read that some wires are diffrent on usdm itr`s. any help woul be appericated

plug & play?

no

 

it won`t plug and play even though i get the whole front clip?

 

you dont need a front clip.

your swap is gonna be the exact same as people who just bought a "complete swap" from somewhere.

everything will bolt in but you still need an OBDI setup.

 

depends on the model of civic. ex/si is easy others you have to wire vtec wires. if you have ?'s im me

he is going from an OBDII motor to OBDI car, its gonna be alot more than just vtec wires.

 

i am going to have to disagree on the difficulty level you have let this kid on to believe. i have a 93 si hatch (vtec wires already there) and i have an itr swap in my car, this is how easy it is. itr swap-97 gsr harness with secondary butterfly wiring cut off cause its not used, the gsr harness plugs into the stock civic shock tower plugs-then an obd1-obd2 jumper harness with p73(itr) ecu or chipped p28 w/o jumper harness. i have both ecu setups. so there you go. it really is easy. if you dont have the vtec wires all you need to do is add knock,vtec solenoid,oil pressure(only usdm),and i think thats it. did i forget anything???

 

can't he just run all of the engine harness plug it into his civic harness. then run a chipped p28, or use a OBDI--&gt;OBDII jumper harness and run his OBDII ECU

if its a usdm itr yes, if its jdm no cause the harness is for rhd so its backwards. like i said it depends on the trim model of the car but also the origin of motor

 

It's not "backwards" in terms of matching it up to the stock EG harness, the harnesses will plug and play, BUT without Vtec wires. Knock tensor isnt needed. Did you mention that your ITR motor had Sec. IB???? Wrong there, the only Integra motor to have secondary intake butterfly is the GSR. You are right about being able to pull the wire from the secondary since it wont work, but the ITR doesnt have that. That's why people buy the Skunk2 IM for their GSRs because its basically a re-drilled ITR manifold, enabling you to run a Ecu w/o secondary butterfly sensor.

he needs a conversion harness
jesus he asked if it was PLUG AND PLAY
i said NO

its not difficult to get one but its NOT PLUG AND PLAY

Correct, he will need an OBD1 to OBD2 conversion harness to use the P73 ECU. The JDM OBD2 P73 is nothing more than an OBD1 ECU with OBD2 style plugs. With the use of a USDM OBD2 GSR or ITR engine harness, the motor could be dropped in with all the OBD2 components and be pretty much be all plug and play. He could also use a chipped OBD1 P28 or P30 ECU and eliminate the need of an ECU adapter harness.
Of course if the car is not a 92 (any model) or an Si/EX/VX, there will need to be some wiring done on the chassis side harness. But to answer the original question, no the ITR engine will not be plug and play even if you order a full front clip. Unless you are wanting to do a front end or even a RHD conversion on the Civic ( ) you are wasting $ buying the full clip.

 

thanks for all the replies this is the story i have a 92 civic dx and have the option to purchase a complete jdm itr front clip. what would be the easiest way to wire into the civic. or should i buy a a usdm harness

 

Don't forget he'll need axles unless he is swapping in that 5lug up front also. 36mm axles don't work so well with US knuckles

 

how much would a complete usdm itr ecu and harness cost? would it be alot easier to do that instead, or is it just as easy to wire the jdm harness minus the labor? and where can you find usdm itr motors?

NO ITR harness will plug and play in that year civic. USDM, JDM it dosent matter.

he NEEDS a OBDII to I conversion and a OBDI ecu.</TD></TR></TABLE>

itr may not be able to be used but obd2-1 conversion isnt secessary to do under the hood. i have obd2 gsr harness on the itr and it plugs right into my plugs under the hood. now i did need an obd1-2 underdash harness jumper to get the stock obd2 ecu to work otherwise you can just get an obd1 p28 chipped to work.

Since your Civic is a 92, IT IS prewired for VTEC, all 92 Civic's are regardless of the trim model. The EASIEST way to drop in a JDM ITR in your 92 DX is: Get yourself an OBD2 USDM ITR or GSR engine harness, this WILL be plug and play with all of the OBD2 components on the motor and WILL plug into your cabin harness plugs on the shock towers. This will take care of all the VTEC wiring and all you will need to do is pin 1 wire in the driver's side shock tower down to the ECU for the Knock sensor. Sound simple enough, I think so?
For the ECU you can easily use the ITR P73 with the use of an OBD1 to OBD2 ECU adapter harness. The JDM ECU is simply an OBD1 ECU with OBD2 plugs, there is no additional sensors or wiring needed. You could also use a chipped P28 or P30 OBD1 ECU as well which would eliminate the need for the ECU adapter harness since your ECU plugs will plug directly into them. Doing this will require the use of a USDM VTEC solenoid and pressure switch or a little wiring trick (super easy) since the ITR motor will not have a VTEC pressure switch.
If the ITR is a 98+ it uses larger outer CV joints with a different spline count so you will need pre 98 ITR axles or any 94-01 USDM Integra, 93-97 Del Sol VTEC or 99-00 Si axles.
