Is it possible to get a 2g to break 500hp and still pass smog, caus that was gonna be my goal with the gsx when i get it but i just dont like the idea of swapping lots of parts for smog, if this isnt possible then what is a more reasonal hp that can pass smog.
 
Check your state laws for the older motor being illegal. It will surprise you. I know of more than a handful of honda guys who swapped older b16 motors into their civics, and got fined by the emissions test people. It IS illegal in arkansas.
 
damn i got it lucky, i could have a 427 under my hood and they would never know....LOL my first time to inspection i had no idea i had a test pipe (came with car), i failed emissions of course, but they said nothing about the absence of a cat. they didnt look under the car or under the hood i watched as they did it right in front of me. LOL but then again, this was the same smog station that setup my car on the rollers, with the front wheels on em and tried to dyno it. LOL before they knew it, they were inches from the car in front of them. i said nothing cause i was hoping to get a free bumper outta the deal.
 
Jim and otherd have already said this, nut I will say it again. It IS ILLEGAL to swap and older motor into a car. They wont see that there is a differance, but if they find out I hope have a good lawyer.

A 500hp smog legal 2G in CA......... good luck.

man turn the boost all the way down, lean it out with afc, shti theres ways, If you have awd theres less of a worry since they only have 1 roller instead of 2 to put your car on, I have no cat, I have a 3" turbo back with a small16g and I was running pig rich at the time of my test and I passed with flying colors.

Im defintely going to have to post a B.S. flag here, anyone else care to comment. There is no way I know of to pass without a cat, if there is, this guy was not trying to do it anyways.

I will take a picture of my PASS car with my readings so you can look salty, just for u!
 
Maybe it is a Cali thing then. I have never heard of older motors being illegal. That would put junk yards out of business for motor swaps then. I couldnt even tell you how many times I have put sb 350's in some car that didnt have an 8cyl to begin with.

Also, it is very possible to pass without a cat, I have done it 3 years in a row, a good runnign engine with good tune wil do that.

You guys are thinking to litteral and not using common sense. Do all small blocks look the same. Does your old lame as 327 look just like a ZZ4 crate motor?? Yes. Most of the time they just take a quick look and see that there is a small block in it and you are good for visual, unless they get picky and look for EGR and other realted items. Most of the older cars all came with a ton of options engine wise. You could get a Nova, F body, Vette, etc.. with inline 6's all the way up to all aluminum big blocks so a small block in a 6 cyl Nove isnt a big deal it could have been there in the first place. Now if you put a small block in a Volvo then I have a feelling they will start to get real picky on there inspection.

Also I fail to see how come just becasue you have done it and got away with it makes it legal and are argument invalid. I speed on the way to work does that mean that there is no speeding law out there?? No, it just means I havent been caught yet. Like so many internet warriors you havent checked the law and just go by what your uncles, mothers, cousin, twice departed did once in 70's. I bet if you actually checked the laws for your state it would say that it is illegal to but a motor that is older then the car into said car.



man turn the boost all the way down

This is a lame statement. Boost on a turbo has nothign to do with an emissions test. For one they shouldnt be pushin the car hard enough to make any boost so the setting is irrelavent, and second to actually hit your desired setting they would have to go WOT so why does it matter if you are at 10#'s or 32#'s???

Previous owner of my car took it through E-check and it passed without the cat (they did sniffer only, no visual).

just a question, how can they tell if its a 6bolt in a 2g. in NJ they dont look under the hood, perhaps its something in the ecu? or, no one can make a 2g ecu into a 1g/6bolt? does it even matter?


The only way they would be able to tell if its a 6 bolt in a 2G is if they ran the VIN # off the motor or knew what to look for (different intake manifold and the dent on the oil pan to name a few). But is anyone that doesnt know shit about DSM's gonna know better to look for that? Absolutely not.

Funny how that's what I said and was pretty polite about it, and I get blasted by guys who are just assuming it's legal.

Like I said. If you have emissions testing i'll bet that your law states you can not swap an older motor into a new car. Just because it looks the same does not make it legal.

You can buy it perfectly legaly however, it falls into the same category as those fake HID lights. They are OFF ROAD USE ONLY but guys use them all the time on the street and mostly get away with it no problem. Doesn't matter if they say DOT leagal on the box, they are not.

I can safely say you're on your stock motor then?
 
i just got through talking with one of my friends who had a honda that got caught with the older engine.
He said he put a b16a1 (OBD1) with an OBD1 ecu, converted his car to obd1, all in his 1996 civic ex. we don't have emissions testing in arkansas now, but we used to. The last year that arkansas had the testing, my friend had his car tested and they noticed that because it was a civic ex (Came with a sohc motor), and that his car was a Dohc, they ran the numbers. He said that he had to go to court, and they ended up fining him like 1000$ and he had to put a stock motor from his year car in it before he could drive it.
He just kept it in his backyard for a few years and when arkansas cut emissions, he got it running again. :thumb:
 
I talked to an RRE guy about what i could do to a 2g eclipse to get the most power and still be carb legal. He said that the most you can get out of a car and squeek by the carb smog test is only gonna net you about 300 hp max. He told me that i would have to run a evoIII 16 g turbo or a 1g turbo and run it on about 14-15 psi. Thats only for smog tests. you can run more boost to turn up the power a little for your everyday driving, just dont get caught speeding and if you do then get ready for a spank by the fuzz and the carb ref :cry: He also said (in contrary to what ive read in the FMIC thread i started) that you can run the Greddy FMIC just as long as you get a better turbo than the 2g stock p.o.s.

I highly suggest you talk to the RRE boys for the full deal cuse some of the ppl here might not know as much as them fellas. :thumb:
