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.

Both fairly straightforward jobs. Really depends how fussy workshop is and how bad the leaks are. If you pressure wash beforehand and it's a minor weep it may not be an issue. ANother option is of cou

It is interesting, the dynamic currently. I think with the camera/database and automated method of checking number plates, they already know what kind of driver you are (speeding fines, previous

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.

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)

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 :)

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.

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??

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

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

Usually they have a tolerance.

^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.

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.

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
