Emission Testing Modified Skyline's

[MRGTR911]

Guiltoy gave me alot of advise for my emiisions Tuning. The guy at the EPA Even told me ill never pass

Theres a guy in Penrith Hitman, He passed my car with all the mods on it with a standard Cat so he done a very good job ... Considering the first time i failed miserably, He has passed cars far worse then mine...

I couldnt believe the look on the Guys face at the DECC When i got passed .... Ahahaha

[Shaun]

i need a cat too mate. what do you have on your car at the moment?

i want a 3" high flowing one better then the xforce ones... or a 3.5" or 4"

we should find a decent flowing one and try get them cheaper for 2...

il start looking around... if you find anything let me know.

My exhaust came with a 'racing pipe', so ive got that on at the moment. I just PM'd the guy who was doing the Metal cat groupbuy, and he said he'll check to see if he can get any others. $300 delivered for a 3.5 inch is pretty good, and im sure theyre the full deal. On ebay, the same ones are $370 delivered.

Im either going to try to make my 4 inch exhaust quiet (with removable modifications), or just buy a standard exhaust. Anyone want to sell a standard r32 exhaust??

Ive used a Below Standard Exsaust which my neighbour at work used to fit on MY R32 GTR IM Currently taking it off and putting my race exsaust back on ... If you need it and i dont know if its fits let me know you can come down and put it on to pass Ur noise test and Emissions ...

[Guilt-Toy]

no i modified my exaust

What exhaust did you use to get 89db stock?

[Guilt-Toy]

can you look into getting one for me too ? does it have the flanges?

cheers mate

Shaun - if mrgtr911 is nice enough to lend you his exaust system then i would use it for the tests as he was able to pass his gtr with it.

No worries, thanks. Where abouts are you?

I rang a few people about the exhaust thing today, and some places will hire them to you for the test. Another bloke said for $100 he'll just say there was a standard exhaust on my car and pass it.

I think i might try to modify my trust exhaust first though. Some places put a solid flange in the exhaust, but drill heaps of 10mm holes in the solid flange, significantly reducing noise. And i can also plumb my external WG in just before the cat, so that if i want to go to the 'track', i can remove the cat and vent the gate to atmo.

The metal cat is unflanged. Just jap sell the Catco 3.5" for about $440, although he said he'll do it for $400. I think Catco do a 4" as well.

MRGTR911 - What mods do/did you have to your GTR as i need to go through EPA for emmissions.

Thanks

[NYTSKY]

Can i ask why you would remove all the stuff you used to pass the car for emissions and db?

If you get caught by the cops with out all that stuff you are going to get defected anyway.

[MRGTR911]

Shaun im in Sydney Bankstown Area if you need any help PM ME Because im keeping the exsaust for future purposes , im Putting my old race exsaust back on but fitting a Electronice Silencer so when i get pulled over ill have less headaches..

Belo - http://www.skylinesaustralia.com/forums/19...ec-t191300.html

Thats my car for sale with a list of mods i had when i passed the emissions test. only thing i had changed was Exsaust Back to standard With a standard Cat . So if i passed this believe me your in with a good chance .. Most important thing is the Tune , If i was you id go to HITMAN .. Hes a good guy And very trust worthy .. Leave the car with him for a week and hell give it back to you passed ... If you have any more problems PM ME ILL oofer my advice i went through 3 weeks of hell ...

NYTSKY, I Didnt neccesaraly Take off many things to pass Emissions , Just put Exsaust Back to stock With Stock Cat , I actually Passed the emissions And noise test With my HKS Filters , so i can tell you i had a really good exsaust on the car, Its actually smaller then a Standard One . the only problem i had was because the EPA Defected me for many Other things which made it hard, The guys at the EPA Know how to defect, Cops dont know there heads from there asses...

In Future if i do get pulled Over i have all Documents, Engineers report , Emissions Test that i have Passed , They could get me for Noise but now that i have installed a Electronice Silencer it is alot Less Noisy , but end of the day if a cop or EPA officer wants to be a Dick they can do watever they like. But this time i am fully prepared, I Have all parts For a GTR to Pass Emissions, So ill offer my help to whoever needs it As anthony ( GUILT TOY ) offeredhis help to me ...

Any more Questions ill be happy to help....

[Guilt-Toy]

Cheers mate, at the end of the day the more legal skylines on the road the more the police will think twice before thinking they can defect the shit out of us. I like to think that skyline drivers can be different to typical bogan type commodore drivers that drive around with defectable cars and i dont mind helping anyone that needs help cos i know it aint easy to do it on your own.

i spoke to a tuner today that recommended getting 2 high flow epa/carb's complaint cat converters installed to aid in the chance of passing emissions as opposed to 1. I'd never even considered it, anyone's thoughts?

[Guilt-Toy]

i heard that it dont work. 2 cats would take a long time to heat up and work properly, especially seeing that after the first test they stop for 5 minutes before starting the second one the cat would cool down again.

Pretty expensive too, id imagine.

No news on the cat. Im just waiting for him to get back to me.

[MRGTR911]

Keep in mind guys i passed with a standard Cat .... you may not need a aftermarket cat...

[Guilt-Toy]

i think you will find most of the standard cats are actually "compliance cats" that the guys that get the cars past the compliance testing use to pass the "simple" emissions test. these could possibly be a catco 3 way or something similar depending on the compliancer.

HELP REQUIRED!!!

Due to a defect notice on my car & with the mods I've got I've needed to do an emissions test, BUT....

WHAT ARE THE GASEOUS LIMITS & HOW CAN I GET THEM IN WRITING!!

Need them for Hydrocarbons (HC), Carbon Monoxide (CO), Oxygen (O2) & Carbon Dioxide (CO2)

Apart from finding Hydrocarbons to be .93 & CO to be 9.3 I'm having no luck to find the limits for oxygen or carbon dioxide. The test was originally intended for just the 2 I already have, but all 4 were tested so all could be good enough to hand in with my engineers report, but also need the proof it complies with the other 2 as well.

If anyone can help me out with this that would be great, as I've already lost a couple of weeks over xmas & new years (workshop holidays) in which time I could have had this handed in already. Only got until the 22nd to drive my car so looking to get it done asap so I can hand it in (ie next couple of days)

Cheers, Nathan

[Guilt-Toy]

Howdy Ossie ! Spewin about the defect...

Did you read the whole thread? what year model is your car? I am pretty sure i put down the limits for the tests for my 95 model car and i think those figures are from around 91 to 98 year models.

You should call the RTA and ask them, they gave me the figures i needed while i was getting the test.

From memory i think the NOX can be 1.93 for the 91 to 98 year models..... go back and read my posts, its in there somewhere.

let me know if you need any help.
