UPDATE!!! The JDM ITR intake manifold is the same as USDM!!

Let's get this over with shall we. Here are links, and stuff quoted from those links. YES, JDM engines will pass smog, they just need the USDM equivalent smog eqiupment.

Some may be asking is my modification legal. Well here you go, if it's not in this database then it's not legal.

Ok, so my understanding is that the JDm engin must be the eqilivant of the american counterpart right? so could i smog a 200 jdm type r moter in a 2000 cx?

 

Yup. You will need a USDM ECU and Exhaust manifold though.
The JDM 4-1 is not legal but, you will have no problems what so ever selling it and then all you have to do is purchase a aftermarket header with a little extra cash on top of the money you made selling the JDM 4-1.

 

Nice write up!! This should clear up the confusion with legalizing a JDM motor swap in CA.

 

I'm hoping. Saw too many people saying it couldn't be done.

 

wish me luck, I am reffing on Friday

 

Luck. 2 visits = no sweat. 1st visit they tell you what is wrong or hand you a sticker.
2nd visit if you fix everything they told you, you get a sticker Well, for 8 bux.

 

Much luck man! My USDM exhaust manifold is in the mail to replace my JDM DC 4-1 temporarily. I hopefully will be refing my car as well in the next two weeks or so.

Thanks again to Spade who put an end to all this "JDM motors are illegal in CA" BS. Good luck to all JDM owners.

 

Wait I'm confused would this only apply to same year only because i have and older verison motor in my 98 hatch can I still pass if I fix what needs to be fixed when I need to see the Ref

 

If you have an engine that is older than your vehicle you must sell it and get one that is same year or newer. There is no way for you to pass even if you upgrade all emissions equipment to your chasis or newer.

 

k cool thx for the info
Heres my dilemma k. i got a jdm b20 long block runnig a ls tranny and a ls head i bought from a friend. I wanna get the BAR sticker imma drop the motor in less than 2 weeks(car in shop) right now the motor is stock and imma add all the necessary smog equiment when i do the drop do u think i will pass. i have a 97 cx and the motor is a 98/99 b20.
any help will greatly be appreciated thxs.

 

Trannies don't matter.
The LS head should be fine since it is a duplicate of the B20.
I don't foresee any problems. Just make sure you have all the vaccum lines hooked up.

 

Bump for Spade, another informative post, wow, do you ever sleep? LOL, anyway, keep up the good research!

 

Do you guys know if a 94 jdm h22a will pass in a 92 civic cx if I used a usdm p13 ecu?

 

good info!!!

 

[QUOTEJapanese Replacement Engines
Used engines imported from Japan can be used as replacement engines as long as the engine being used has been identified as functionally identical to the original engine.[/QUOTE]

So how can a civic have a JDM B series engine if this quote says that it has to be functionally identical to the original engine....

the way i understand this is that a 95 del sol DOHC VTEC can get a 95+ JDM engine to replace their blown engine....

not a 95 civic with a D series being replaced with a 95+ JDM B series???

I think that replacing a D with a B is not functionally identical....

The only way that I can see that they are functionally identical is that they are engines that have cams, pistons, and they operate like any other engine....

is this what it is saying or what??

 

what he said

 

Spade should become a state ref...

 

not trying to be a dick or the bringer of bad news. but its not gonna pass. 2 reasons. if you read the site its says.
basically head swaps are illegal, i was going to build a crvtec untill i read this info

and second
the CRV is a light SUV, your putting a SUV motor in a passenger car.


im looking into this right now.. the ref is gonna call me "in the next 2 business days" When i talked to a ref this summer he said it was fine. As long as the JDM motor matches is USDM counterpart. Its like getting a engine change first.. then swapping that engine change for a JDM motor. Thats the only way i can explain it. hope that helps.. and ill let you guys know what he says soon

 

thanks keep us posted with that REF!!!!

 

IT IS POSSIBLE! Here you go https://honda-tech.com/zerothread?id=375500 Read this, I went ahead and called a Irvine Smog Referee and asked him all the questions. TRUST SPADE HE KNOWS WHAT HE IS TALKING ABOUT!

 

just making sure.....

you know how those things are written...they sometimes dont make any sense....

I need some hope..for getting a JDM engine....

know what I mean..

they are cheaper, and seem to be a lot more around than the US ones..

 

GET ONE, YOU WILL BE FINE. If I were to do it over again, I would have installed the motor first, then before I could have added any additional bolt-ons, I would have taken it to get it smogged and get the BAR sticker. After you get the bar sticker, you no longer have to worry about some smog technician saying, "Um, I think this is a different engine "

Good luck. If you have any further questions, call a ref yourself. They are more then happy to answer all of your questions and myths about JDM engines.

 

man good luck, hope it goes good for u, ill be in the same boat soon

 

thanks for the post man it is really help full
