Emissions test for SR/RB?? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

BRZFanatic · 06-17-2012, 05:05 PM

Hey guys, I've been in love with 240s for a long time, especially S14.5s. I grew up around muscle cars and do not know much about sensors and ecu's and all that, which I know is surprising for a guy my age. Id like to buy a RB25DET 240 but I just found out about the whole emissions problem. Speaking of a 240 S14.5 with an RB, what would be the best way to pass inspection?? I live in PA and I think we are required to have OBD2 inspections here.. I would really appreciate your input, as I need to buy a car soon. Thanks.

Look up the details on your local dmv website It's different in every state

Wow. Really, just wow

According to Google, and many other places... RB's and SR's in RWD configuartion are 100% illegal because they don't have OBD-2 software. Long story short, if you have an OBD-2 240sx (96+) and your state requires you plug in, you're pretty much SOL.

Talked to JWT about it, they mentioned it *may* be possible if you took both stock harnesses, mounted all KA emissions hardware, correctly connected it, converted eeverything over, and had them rewrite a KA ECU to run the swap.

I don't think its worth it to money that hard... could just do a 95 and *explanation stifled to protect me from legal repurcussions*.

Bottom line: JDM Motor swaps are generally illegal for US emissions purposes.

Get a chassis thats not OBD-II, meaning older than 96, you should pass the sniffer with a proper cat. Now, if you guys have visual inspections too, then you probably wont pass unless they dont give a shit as long as you passed the sniffer.

Thanks for your input flip. I am good friends with a mechanic but I haven't been able to find some in depth info for my state on the web at least. And Future, SERIOUSLY?? That really helps a lot. I said it was a noob question, I just needed some confirmation from you guys. And "Wow" does not help answer my question. What were you drunk?

SuperBlackS14 · 06-18-2012, 10:35 AM

Look, I'm from NY, (upstate, OBD-II + safety) and I lived the OBD-II SR-dream. I said forget it and went KA. Wasn't worth the effort. 95 is the only year S14 that isn't subject to OBD-2 standards.

If you're married to the idea of a JDM swap, go with a 95. If you want emissions legal power, keep the KA and Turbo it. Or get an LS3 E-Rod lolz.

Good luck to you man.

I couldn't find any information on OBDII RB's but I've read on forums in the past that Type-X SR20det's are OBDII but this could be false, if you're interested at all I would recommend investigating... or worst case scenario.... MOVE TO FLORIDA! WE DON'T GIVE A FUCK HERE! lol, I have an RB swapped S13 and an SR swapped s13.

BRZFanatic · 06-18-2012, 11:19 AM

ya lol thanks guys. I know what I need to do now. I really appreciate the help. And other than Future's post, this forum is awesome, I hope to keep in touch, as I will be getting a 240 very soon.

Wrong, Japan does not have emissions so there is no such thing as OBD-I or II in Japan. So trying to make an engine that isnt even OBD-I compliant try to pass OBD-II inspection is damn near impossible. OBD-I is passable with a good cat.

BRZFanatic · 06-18-2012, 07:30 PM

So I still might be able to get an S13.5 with an RB to pass inspection...

thats quite a lift (phew) this fiasco has had me stressin all night haha. Looking at 4th gen Camaros and such 0.o a cat is no problem, but I will definitely be looking at my laws regarding emissions. And Im buying a few books on electronic engine management. Like I said, I know carberators, not ECUs. Once again, I appreciate all the help. Now lets outlaw this emissions crap!!! Haha as if. Nothings ever easy.
