Smog Legal Japanese engines? Inquire within.
Ok, first let me give you all some background information. I work for an emissions lab where people bring their euro market cars to be certified for the US. On a one off basis, this is really expensive, in the 10's of thousands of dollars. But, my boss said CARB may be able to issue an executive order that would cover SR20's if its handled correctly.
So my questions to you with SR's is... 1. Has anyone taken their car to a smog station and had it sniffed? If so, how close is it? do you have any numbers? 2. Do SR's have evaprative systems? i.e. a charcoal canister etc...? 3. Is anyone interested in possibly paying a reasonable amount to have their cars able to be street legal so you arent freaking out every two years when smog comes around? The reason I want this is because I want to SR my car, and not have to freak out when smog comes around about finding someone, not to mention rules are getting harder about fudging a smog test and penalties are getting higher. Also I dont want to have to worry about getting my hood lifted if I get pulled over. This wont just apply to SR's it would probably be possible to do RB's and CA's also, as long as the chassis is USDM. Hope some of you are interested.

Of course people are interested and yes, SR's use a charcoal canister. Just start listing prices and what kind of parts people would have to run to make it legal. Would you have to run stock injectors, MAFS, BOV, ECU or would you have to have a stock SR because that's no fun. Or is it solely based off of passing a smog test and the parts don't matter? There are people around the country that pass smog with SR's so I'm sure it's possible.

Well I know people around the country do, but I am talking about a CARB executive order.
I dont know what its going to take, I am just trying to guage interest and to have facts and not opinions to give to him. thanks for replying though

This is one of the main reasons why I sold my SR powered S13.
Out of curiosity, which emissions lab do you work for? Also, have any exective orders been issued in the past? If so, for what cars? Pablo

I've heard of SR's passing the sniffer test with no cat. Not sure how true that is, though.
And yes, I'm sure LOTS of people would be interested in this just so long as its 100% legit (rather than some loophole that won't be open for much longer like the propane idea). |

Our standards aren't quite as strict but there have been a few people on the boards that said the sniffer test just fine...but only failed when they popped the hood.

Lets just try and get e85 going as well. 105 octane for the streets and easily passing sniffer would be nice. Ive never understood the visual test. If you pass the sniffer and have all the other required equipment, why the f does it matter?

Well in california there is alot of extra laws the other states dont have I dont know all of the specifics but I do know
You cannot have a breather, if you modify the engine such as an intake, exhaust, chip, ignition parts etc, it has to have a CARB sticker. the evaporative system must be intact. you cant have any disconnected vacuum lines. your timing has to be within a tolerance of factory spec your gascap has to hold pressure... um thats all I can think of. The cars we have issued E.O's for are Porsche 959's (mostly) McLaren F1's various ferraris and lambos A few different non-diesel mercedes and BMW's and alot of different smaller Harley Davidson manufacturers as well as chinese, thai, korean, italian and indian scooter manufacturers. and also aftermarket companies such as nology. It would be 100% legit, CARB E.O. in hand if it works out, the biggest factor right now I think is getting enough people in California interested.

the biggest problem isn't interest... it's the fact that since SRs arent legal anyway, NOBODY has a stock SR with all the emissions crap intact (yes, we all know some lame guy with a stock SR, its just a generalization). Also, no SR parts have CARB stickers because the SR isnt CARB legal - that comes later. It's an excellent first step, and once we start talking numbers I think a lot of people will get on board, but a bunch of us will still be dodgin those vis inspections.

Problem is, you're dealing with a community of very limited funds and very high ignorance. I'd say 75% of current 240SX owners don't care to spend the money for something tangible, and don't understand the benefits or the pitfalls of failing/passing legally when they can just throw change at a dirtball emissions tester and forget about it. These kids simply do not care about the fact that an SR swap of any kind is still illegal, no matter how cool it is. I think you're going to have a hard time proving that it's a viable option for an EO number and that it will benefit those drivers in the long run, especially since they'll have sold their cars or stuffed them into a tree and moved on to the next thing when you finally have something solid formed. Good luck but don't get your hopes up too high.

this thing is analogous to legalizing/importing jdm stuff like skylines,
most people would want it, yes, but most are broke/cheap unlike those mclaren, lambo, porsche, harley owners but go for it, see what you can find/do, maybe this thing can work out... there was a couple people here that works for emissions/smog centers, they should have alot of numbers for you... if they're willing to share... |

I really don't think an SR will pass CA emissions, cat or not. I don't think sr's have an egr, which is one reason the visual component is required on a test. I don't think any jdm cars have an egr for that matter. The egr lowers CO2 levels, so when my car was on the sniffer (with a cat), the CO2 was off the scale. Plus, every 240 I know of is getting those damned Test Only notices. Maybe you can weld two cats together (some cars come with two).
On a side note - I was reading the uk sr20 fsm and I think the UK sr's have an egr, which might make passing easier. It might be easier starting from there. Just register the car in an area where smog is not required (except when selling the car). That would be in a gray area on this map: http://www.smogcheck.ca.gov/ftp/pdfdocs/program_map.pdf I thought about doing that, but it still won't stop some overzealous law enforcement officer from ruining my day with a ref ticket. I keep hearing that they're going to change this law, but it hasn't happened yet. As far as legalizing the sr20 - I don't think it's gonna happen any time soon. We're all too poor to shell out the cash for that. And if I had that kind of cash, I'd have a BMW. |

This pretty much only applies to people living in Cali, you guys in the other states pretty much get away with whatever.
R240- I think you hit the nail on the head, seems like people dont care if they can find a way around the law. The reason I want this done is to be able to have a legit SR20DET powered 240sx. I dont want to have to look over my shoulder all the time and worry about getting reffed. I also dont want to have to pay someone to pass my car illegally. My goal is to get this cert around $300- 400 per car for the life of the car. Not upwards of $150 bucks every time smog rolls around (what I have heard it costs). Not to mention having the comfort of if I do get reffed having the paperwork saying that my car is legit. Philthy- An EGR is just one means Nissan used to cut emissions, just like a catalyst or air injection. Under a CARB e.o., if the car passes tail pipe emissions it will not need it. There are plenty of cars without Exhaust Gas Recirculation that will pass smog. My bottom line is, is anyone interested in paying around $300-400 to have a certified SR or RB or CA powered 240?

From: http://www.smogcheck.ca.gov/StdPage....y-May_1996.htm "EGR Functional: During the Smog Check inspection, the technician performs a functional test of the EGR system per the vehicle manufacturer's instructions. This ensures the EGR system is operating as designed. EGR Visual: As part of the Smog Check inspection, the technician performs a visual inspection of all emission components the vehicle is equipped with, including the EGR system. The technician visually inspects the EGR valve and associated plumbing for defects or modifications. The technician will either pass or fail the EGR visual test based on observations made during the test." But please sign me up for the legalization. I'm in. |

Philthy- This refers to vehicles that were equipped with an EGR. if you look in the wording,
"As part of the Smog Check inspection, the technician performs a visual inspection of all emission components the vehicle is equipped with, including the EGR system. The technician visually inspects the EGR valve and associated plumbing for defects or modifications. The technician will either pass or fail the EGR visual test based on observations made during the test." To my knowledge no JDM engines are equipped with EGR's because it is probably the most barbaric way of emission reduction possible and robs you of alot of horsepower. Therefore under the certificate an EGR would not be required.

for anyone who passes smog , thats great but you will not pass a test only station with an SR. and the visual part is bullshit, my car passed sniffer with no cat. no egr, with upgraded fuel pump. no charcoal canister, no egr. just visual that gets us.
