The Epa Thread/Roadworthy Thread

I have to get an EPA noise and emissions test done fairly soon and was wondering If I could get some advice? I have a R33 gtr vspec series 3, current mods are, -5 turbos, power fc, greedy elec boost controller, nismo fuel pump, fuel pressure regulator and injectors, cam gears, exhaust, and pods

I was planning to remove the boost controller, return the injectors and ecu to stock. I believe that the turbos shouldnt be a problem as they are nearly the same as stock. Do I need to return the fuel pump and pressure regulator to stock, I know Im meant to but will they effect emissions if the stock ecu is controlling them and would the inspectors be able to tell between the stock and nismo items. I will quieten the exhaust and leave it that way. Also if I refit the stock ecu will I need to get the car retuned? And is there a difference between an ecu for a gtr and gtr vspec. Any advice is appreciated. Thanks.

Any advice? Just like a bit more of an idea to what stock parts I'll need to start collecting/replacing. Cheers.

Everything must be factory that you can see.

Turbos, you cannot... so obviously they do not count.

i have a intercooler hole in my engine bay. can i get a rwc if weld it up? or have to weld it and get a engineers certificate? thx

[R31Nismoid]

Depends if you've been defected or not.

If you have not, you might get away with it.

If you have, unlikely as it'll be listed on the defect. Any legit RWC place should not honour it without an engineers.

[Bruce_Sun]

not defected.

should i do something to make it not so obvious like weld on both side and paint the new metal plate to make the color same.

thx

You should make it as close to factory as possible mate, closer it is, the better.

Even if it takes more time/money... as once you get defected for it, I'm not sure any engineer in Vic actually signs off on it (if you have airbags)

[Bruce_Sun]

no airbag, it is a R32, is it going to make my life easier on this? damn stupid previous owner!!! they cut a hole there and not using it

No airbag means any engineer will easily sign off on a PROPER repair job should you get defected (requiring engineers)

So you shouldn't have any issues if you do a good repair now, and then just go about your normal life.

Being you'll already have fixed it, no-one will know otherwise

is a r32 skyline GTS rb20e airbox can fit in a gtst? can i pass rwc with it?

[HIZOKU]

I got defected for not having a battery wire with tie downs every 60mm and open ended wheel nuts is that BS or can i be done for this?

i got done for other things but just confused about these

^Wow that's harsh.^

I cleared mine EPA today. Even a standard 32 cat back exhaust was 93 db so it failed yesterday, everything else was ok except the guy thought I had diff fuel pump coz it was noisy. Pulled it out and its nissan

Had to get a new muffler and it made it 84 db today. It's been 6 months and I will finally have it back on the road.

Not sure about the battery wire but my car from factory has open ended wheel nuts as does just about every car I can think of that has steel rims.

[R-SPEC]

silly question - is having a stock airbox with the lid off considered a form of aftermarket intake/defect?

[wht510]

Battery wire tie downs every 600mm (60cm). From memory that's the requirement, but sometimes it's better to have every 40cm.

It's a fair call, but pretty pedantic. If I was the copper, I would've said "Fix this and you can go on your way".

As for the open ended wheel nuts.... Not sure!

I got EPA'd at a defect station at 90.4db...and was told id get a letter warning that it is close to the limit.

I just received a letter saying 94db and to get it checked/fixed.

Im wondering is there any % leeway on these tests like speed cameras have 3km... or is it 90 flat. 90.1 over = defect??

[wht510]

You sure you didn't miss read the reading of 90.4?

On a serious note, do you have paper work to show 90.4?

Usually they have a tolerance.

[alr33x]

i think 90 is 90 but just get it fixed and be on your way, lucky you didnt get the 600 fine to go with it i rkn

^That

Either way, you are illegal so what it "is" its honestly irrelevant.

You need to be 89dB 4900RPM if memory serves me correct for the RB25... so regardless of 90.4 or 94.0 - you need to fix your exhaust.

There is no tolerance far as i know however. If it's 0.5dB over, you are over and will fail. As the EPA people "tell" you, thier meters are perfectly calibrated.

I know for a fact they are not (having gone to two testers and had a variance of 2dB), but thats just how it goes really.

[2000gtt]

$600 fine?!!?! is that for repeat offences or 1st timers?

i called the epa up, it was 90.4db, but 94db on de-acceleration...

Even after all the defects i have seen cops hand out, i have yet to see even the best cops give a defect for the battery tray hole.
