I've already done a search on this, and didn't find the answer to my specific question.

Is the JDM ITR motor (96+) OBDI or OBDII? I read on one website that "most" JDM motors stayed OBDI. If it is OBDII, what kind of problem is this going to give me when I am wiring it into a 92-95 EH2? Is there a harness conversion or is it simple wire placement? Thanks for your help.

P.S. One other side question. Is there any advantage to buying a USDM ITR motor over a JDM ITR motor. I know that the JDM motor has more HP, but why would someone buy a USDM one? I know there are a few people on this board who have them so maybe I can get a good answer.

 

JDM ITR engine is OBD2.. The only thing your gonna need is a rechipped ECU, someone on this board does it.. Kenji I believe.

Also, there is always an advantage to buying a USDM engine over a JDM engine.. You can identify correct mialedge easier than a JDM engine. Some people prefer USDM for emission reasons..

Theres alot of people in this forum with this swap..just look around

 

I've heard about the Kenji P28 ECU being used by a lot of people on here. Will this make the wiring basically plug and play. I am also aware that I am going to need a VTEC solenoid off of a USDM b-series engine. But will this ECU make it to where I can use my stock wiring? Thanks

 

If you just use the OBD1 ECU there isn't any problem at all. Its just like any other EG / B-series swap.

Which ECU is the OBDI ECU for a JDM ITR motor?

 

There isn't an OBD1 ITR ecu.

You'll have to run a P28 (you don't HAVE to). I'd suggest getting one from kenji..

good luck

All JDM motors are technically OBD I. But when they went to OBD II for America Honda changed the plugs to OBD II style plugs. So the ITR is OBD I with OBD II style plugs.

Get a rechipped ECU and a USDM vtec solenoid (JDM one is has oil pressure tapped off). Oh and YOU DON'T NEED A DIFFERENT ENGINE HARNESS. USe the one that came with the car. Even though is looks as though it won't connect to the chassis side of the harness it will....I know because my car is set up like that.

 

If i buy the ITR swap am I going to be stuck with a p73 ecu that nobody wants to buy or does it actually hold a little value?

 

Some people think that the JDM ITR ECU is actually better then the USDM ECU. You'll be able to sell it simply because its from a JDM ITR motor but it really isn't worth it (Esp with that 113 mph cut off).

Get the motor and worry about that other stuff later.

 

Hey you're in ATL too? But anyways, the reason I ask is because I am getting a friend of mine that works at Nopi to call and get a price on the ITR swap (just tranny and motor) to see what the price difference is and see if I will come out better just buying the whole swap.

 

WHo @ Nopi and what do you mean buy calling to get a price, from where and price difference vs who/what company???

 

Local friend name Alan. He lives in my town. Hey's got some "connection" through a company, I believe it is Best Japan Motors.

 

Best Japn (I assume the one in Marietta) only gets B16A's. If they do get B18C's that new news. Also their wire harnesses are cut. Just giving you a heads up. You should try Osaka Motors in Canada or Nippon Motors or Honda Motors Online for a JDM motor they all have good prices.

I was asking who you knew @ nopi because I used to work there unfortuneately for a little while. Alan is the guy that kinda looks like Chris Ellington, had a 1gen DSM a short while ago right?

Yea, he had a 1st Gen Talon Turbo. Pretty fast car but ugly as ****. He just got a 95 EX though. That was the company that he had told me about before and yes I believe it was out of Marietta.

I've looked at hmotorsonline.com and osakajdmmotors.com and both of their prices are reasonable ($4800) and $4200 + shipping of course. These are complete packages with axles, ecu, wiring harness, motor, shift linkage, and tranny. Do you know of any places to get a longblock/tranny combo or is the whole swap the best way to go? Also do you know if these places cut their harnesses?

 

Osaka, Honda Motors online, and Nippon DON't cut harnesses. Best Japan does. Like I said I knew about them for a while and I don't believe they get b18C's @ all but check them out. Just be prepared to buy a new harness.

Tell Alan Hurell says what's up. I can believe he bought a civic. I thought he was Anti-honda (Or maybe it was someone else I was thinking of).

You really can't go wrong with either of those prices to be quite honest. Even if they don't come with mounts or axles. Those are still good prices.

 

He actually had an EF Si before that Talon and was looking for another Honda the whole time, i dont think he is anti-Honda.

Both of those prices DO include axles AND mounts, so I suppose it's going to be rather difficult to find a better price than the $4200 from Osaka

 

They have the best deals going that I've heard of fro ma legit shop. Can't go wrong with them.

 

ok i have a question. im not completely understanding this. say i have a 92-95 hatchback , vtec wired or non vtec wired. osaka's jdm itr comes with everything: motor/tranny/ECU/axles/shiftlinkage/wiringharness etc. Can i use the ECU they send me? What all will i need to buy? I will be getting swap done by a shop. help me out so i know.

EDIT: how much is a USDM vtec solenoid anyways incase i need one?

bump i need to know ^ ^ ^ ^

 

Yes you could but you would need and adapter harness not to mention more wiring hassles. I would recommend selling that and buying a chipped OBDI P28 though.

 

but would i need a vtec solenoid? a USDM one i mean.
how much do they run for?

 

Dont they all come vtec wired?

 

1992 Civic's are all wired for VTEC on the cabin harness side. Using a VTEC engine harness will eliminate running wires. Some early model 93's I have seen also have the VTEC wires embedded, but it's rare and usually Candaian models only. I had a Canadian 93 DX hatch (made in 3/93) and it was wired for VTEC.

 

Wrong.
The JDM ITR vtec solenoid does not have the pressure switch.

If you are going to be running a usdm richipped ecu, you will need to purchase a usdm vtec solenoid.
