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.

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.

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)

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 :)

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.

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

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.

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
