Basically started off with a random breath test on doncaster road near westfield. Blew clear, then like 20m down the road another lot were set up - the EPA for random emissions testing.

My mate got defected in his brother's 300ZX TT tonight - too low, bald rears and no number plate lights. What interested me more was that he passed the EPA random test. I will check with him tomorrow, but i'm pretty sure that this car has gutted cats... What worries me now is that if i get random EPA tested, will my car pass the emissions test...? It has a 'race cat' but i suppose the question really is - can the car still pass emssions without the cat?

Has anyone ever been random checked by the EPA?

OK, by what i know, they do the whole noise test and emissions test on the spot, i guess they'd do a look over of your engine bay too.

But still, CAN the car pass the emissions test without / with a gutted cat? Does anyone know?

Faulty or no CAT will definitely show up on EGA as they will get a high hydrocarbon reading. I haven't seen the equipmeny they are using at the moment but I'm reasonably sure they haven't changed the way they check. As for the $10,000 fine, I've never heard of this being issued against any individual.....has anyone else?

Hey Inasnt

I went for my EPA test at Macloud today... (I was suppose to go last week, but I had put it off till this week)

I passed the noise test right on the nose at 90db !!!

talk about close....

As for Emissions test - didn't even test it.. he said skylines run very clean - so he didn't bother to test it... The fact the my Low Fuel Warning Light was glaring him in the eyes while he did the noise test may have atributed to his desission not to do the emissions test.. :P

But the big thing is that the Sound test was done at 5100 rpm

(not the usual 3200 rpm that the exhaust shops test at)

He said that a Twin Turbo 2.6 L has to be tested at 5100...

At the EPA they work off a more detailed Vehicle Reference Book then the epa approved exhaust shop test centers have...

And as the test centers don't have the detailed book - they test at the default for a NA 6 cyl. which is 3200rpm....

They also also asked me if I had changed my exhaust since my last EPA test in november 2002 when it tested at 85db at an exhaust shop test center... I said "Yes, I changed it when I got this latest epa notice... if I am going to get epa notices while running with a 85 db muffler then I might as well run one that is 90db"

He said "fair enough" and passed me :P

sideways

they tested my car at 5100rpm 2. I was gonna ask them wtf they were doing but since it only read 83db with thew stock exhaust i used for that day i didnt say anything.

My car was actually running rich as they told me coz i put back on all the stock stuff which changed all the flows. Did a tall guy with glasses and grey beard test your car?

  • 1 year later...

i think theyre supposed to test at around 3/4 of the redline

for engineers certificate for my rb25 silvia, it test was carried out at 5625 (3/4 of 7500) and did 89.5 dBa on (what i think is) a 2.5" full exhaust with canon (exhaust pics here)...this is nsw though, not sure on differences with vic

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
