I have a 96 JDM ITR Engine. Does it have a purge control solenoid valve and evap canister? I need one for emissions to pass inspection. Not sure if that is on the JDM motors. I know the USDM ones have it. If it doesn't have one what parts would I need to buy? Does it have the ports for the vacuum lines or would I need a new intake manifold? Thanks.

FOR CLARITY:
Car has a USDM P73 ECU so it will throw a check engine light for it I think. If there is anyway around it that will work too. It's not a visual inspection it just needs to have no check engine lights to pass.

Thanks

 

It has an evap canister, but I've never seen a JDM engine that came with a purge valve. What kind of car do you have (year/model/trim)? What wiring harness are you using?

Anyway, if you've got an OBDII car and using your stock wiring harness, then you can just take the stock fuel rail off of a B16A2 which is where the EVAP purge valve is mounted to, then use your existing plug to connect to it.

 

It is a stock 96 Honda Integra Type R (RHD JDM car). Needs to pass emissions so needs to be OBDII with no check engine lights. So I am in the process now. Have the USDM P73 and am adding the sensors that are different between the JDM and USDM models. One of them is that it throws a check engine light for the purge valve since it doesn't have one so I need to add one.

I thought it was mounted to the intake manifold for some reason but it looks like I need a new fuel rail with solenoid?

 

It's mounted to the firewall on ITRs. You're going to have to wire in all those sensors to your existing RHD harness too.

Do you already have the USDM header, cat and b-pipe with secondary o2 sensor? What about the crank angle sensor? The USDM P73 ECU will be looking for all those sensors.

 

My understanding is the differences will be:

1. purge solenoid which I am trying to figure out in this thread exactly how to go about that.
2. secondary 02 which I can weld a bung in and wire up.
3. oil pump crank fluctuation sensor and pully which can be bypassed with the CFK trick
4. VTEC pressure switch which i heard you can tap the vtec pressure switch signal wire into the vtec solenoid wire.

Hopefully I am understanding correctly.

 

You will need to drill and tap the manifold and install a hose barb to run the evap solenoid. There a a very good write on here on how to make a JDM ITR motor pass, I'll try to find it.

 

Oh man that would be awesome. I didn't come across that in my searches.

 

Ok I searched for a while, can't find it. You already know all of the systems the jdm motor lacks. You need the crank (CKF) sensor, vtec pressure switch, purge solenoid and secondary o2 sensor. Along with all of the regular emissions equipment a usdm car has. As you already know the ckf and vtec pressure can be tricked. You also need a USDM P73 ecu. The jdm itr manifold lacks the vacuum nipple for it, pretty easy fix with a drill tap and hose barb fitting

If the link doesn't work search legalizing your Jdm itr motor or check the FAQ. Also I think super street Sean k did a write up on how to do it too. Good luck post results.

 

That's it, didn't remember the title, thanks.

 

Thanks. I read the thread. So I need a USDM Intake Manifold and purge solenoid off of a USDM ITR (the thread said the JDM Throttle Body will be okay). Any differences between the years I need to be concerned about? Will any B16 Intake Manifolds work? Everything else should swap over fine right? Thanks for all the help!

**edit** I think I am just going to tap the stock manifold. So is there any write up on adding the purge solenoid or is it straight forward. Not sure how the wiring and vacuum lines would be run. Is the purge solenoid different on different Hondas or will any b series one work? Thanks again.

Another article hope this also helps

 

Your USDM car should already have a purge solenoid and all of the emissions equipment. Its just 1 vacuum line.

 

The CAR is a 1996 Honda Integra Type R (JDM Car. So JDM engine and car). I am making it legal and need it to hook up to the DLC and be OBDII since it is a 96. I am in the process of doing it now. The other 3 items are pretty straight forward as a bunch of people have helped me with that. Also the wiring up of the DLC should hopefully be straight forward too.

I am just trying to sort out actually INSTALLING a purge solenoid on a car that never had one. I think this might be a little tricky which is why I made this thread to try and figure it out. I know I need to buy the solenoid, tap the intake manifold and run some vacuum lines. Not sure about any wiring or exact details though. Thanks for the help.
