Are you guys saying that SOS 2.1 Autorotor with the intercooler making a sweet 400 whp will pass emissions? If so I may be thinking of selling my ctsc whipple.
ScienceofSpeed Supercharger?
- Thread starter NSXCessive
- Start date
We have passed 4 cars with our supercharger and intercooler through Arizona, which has the same standards as CA, the strictest in the country.

Anything can be made to pass smog tests, aslong as the car has a proper tune and a good set of cats. As for reliability and drivability a proper turbo set up is just as reliable as a charger! I put about 12,000km since turbo and drive everyday problem free, and will be doing a couple more this winter so there will be three turbo nsx's rolling around Toronto this summer!
Did anyone see na1tor's incredible turbo last summer? After his thread a year ago, I was amazed and shocked and awed and terrified of that turbo, all at once!
Where were you all summer na1tor? I was looking forward to seeing you car. Never did.
If you can plug in and have cats, any FI choice should pass (I think). I wouldnt expect that the SOS SC would have problems passing, but you cant go full AEM EMS I dont think.
Chris, can your SC run on the stock computer or the AEM F/IC piggyback?

Ya, the computer was confused because I had Clare's DNA all over me.
Ohhhh yaaaa, that just happen'd bitches!
You CAN get the Standalone AEM EMS to pass emissions but that's a completely different tuning session altogether... You'll need to put the car on the Dyno and hooked up to a 5 gas emissions analyzer and tune the AFR and EGR duty until the HC, CO and NOX are all well within passing limits at the RPM and load boundaries the emissions testing is conducted under.
I've got a JDM H23A Vtec engine in my Accord running off of an AEM EMS and after spending just over an hour on the dyno with a mechanic holding the RPM at around 3k in 2nd gear while I tinkered with fuel and EGR duty, I was able pass with flying colors and save the calibration so I can load it up every 2 years for the Etest. Idle is easy to tune since NOX is not a factor.
If anyone is thinking of going full Standalone AEM EMS, I'm pretty confident I can get it pass emissions as long as the car was passing emissions before the SC install...

Didn't happen to me so I guess we know who's the girl...
This thread is making the gears turn in my head....
Selling my GMSC will pretty well pay off a huge chunk of a na1tor turbo kit. If my aem ems can be tuned to pass emissions this might be do-able.

If John is thinking about spending money on his "project" then consider it already spent!
Just note that most Turbo kits delete the necessary emissions items that enable the car to pass so make sure those are retained or can easily be bolted back on and functional.
- EGR is mandatory for emissions (obviously needs to be wired up as well)
- Cat converters are mandatory (most turbo kits remove the cats, SC kits keep the OEM exhaust)
- Wideband O2 sensors configured and used with AEM (should come standard with kit)
As long as these massive FI kits can be tuned for a STABLE idle at a solid 14.7 AFR and low/medium load to run at 14.7 AFR, I can get them to pass. FI kits that cannot be safely tuned at around 14.7 AFR in low/medium loads or idle will never pass. I would inquire to ensure that the kit you buy can do this.

Bad timing for me as I was in the midst of the 02 Conversion + paint, suspension, headers, stereo etc... and all at the same time trying to get the car ready for XPO budget was blown last year. I also knew something was in the works with SOS's Charger so I held off. I'm sure the winner of the XPO CT are happy a great deal on it & thousands less than MRSP both CT & SOS chargers that is!
My mechanic also thinks it shouldn't have a problem passing emissions testing. For the guys thinking of doing engine work I also believe any of the 3.3L, 3.5L etc different displacements from the stock engine would qualify to be tested in the hot rod class. I believe or even putting a 3.2 in an early NSX 91 to 96 would qualify as well? I had an old '91 Integra 1.8L which I swapped to a 1.6L VTEC engine and it from that point was tested in the hot rod class funny because it was smaller than the original displacement engine... crazy huge allowances in testing there. Of course I had to prove the motor was different, carried the paper work for it when testing time came.
Found this tid bit from back in my integra days...
"Hot Rod: a motor vehicle in which the original motor has been replaced with a motor of a type not installed by the manufacturer on that model YEAR of motor vehicle."
Well if you do sell Chris might give us a better deal if we roll more than one across the boarder? If anyone else is interested PM me...

Haha those 'gears' in your head I think its called the winter blahs... sounds like you are on the way to Turbo territory?
The biggest problem with the Hot Rod class for emissions is that if you replaced your motor on or after Jan 1999, you must comply with current Drive Clean standards and full Etesting.
In other words if you replaced your engine 11 years ago, you may qualify for a Hot Rod status, otherwise, if you replaced your engine anytime after that, or plan to, you need to fully comply with current drive clean testing of the year the motor was replaced.
If your car is a 1987 vehicle and you replaced your engine on or after Jan 1999, it would need to be Drive Clean tested as a 1999+ vehicle and you technically would need to be tested as such... not that you would be silly enough to volunteer that info up yourself, but technically speaking, the mechanic or shop that did the swap is breaking the law by NOT submitting that info to the Government and can lose their certification / accreditation to service vehicles. The end result would be that you would receive from the Ministry of Transportation a renewal notice for your 1987 vehicle that will now require emissions testing as a vehicle of the year you installed the engine.
Now there are many stories of people bringing their modded cars to facilities and they tested it under the Hot Rod standards, but that is not actually legal unless you provide proof that the engine was replaced before Jan 1999.
This is not opinion, just facts.

Yes, the definition of "Hot Rod" is one which a vehicle has had it's engine replaced with an engine of a different year.
However, the testing requirements of a Hot Rod follows the above mentioned rules...
"Hot Rod" engine was replaced before Jan 1999, use more lenient Etest limits (based on year of original car - not engine)
"Hot Rod" engine was replaced in 2010, treat "Hot Rod" as a 2010 vehicle using 2010 Etest limits

Garrick, stop it...you're killing my buzz. 
There is another customer in Toronto looking to buy the supercharger. Drop me a line, and I'll put you two in touch.
take care,

Don't worry John, I can get the AEM to pass 1999+ emissions requirements as long as...
- the EGR is present and hooked up to one of the AEM optional or configurable outputs (which it should by default)
- cats are hooked up and functioning
- The kit doesn't require that you run richer than 14.7 at idle and at 2,500 rpm with medium / light load
All I'm saying is that there is no easy way out unless you do a proper Emissions tuning session or just don't renew your sticker...

Man, I can't stop looking at the pics posted in the other thread of na1tor's turbo setup. Can you imagine what that'd look like with my see through taitec rear diffuser?

It would look like a beast! But I don't think there is any room for cats under there... See if he's able to put some high flow cats in for emissions...

It would look like a high tech rice-cooker... burns rice fast... :biggrin:
I dont get how a AEM EMS can pass emissions. What do they plug into? I get that it can pass a sniffer test, but plug in?
HA HA, I said butt plug. That'll get Stu's attention!

AEM EMS completely replaces the ECU and is "plug and play" so it connects to the OEM harness. It controls everything that the OEM ECU can control. So adjusting the fuel maps will tune the AFR but activating the EGR requires some customization that most shops won't bother messing with.
The AEM is already hooked up to the EGR, but you have to configure the AEM to control it. The hard part is the tuning which is a balancing act between HC, CO and NOX. You can even configure the AEM to turn the check engine light on and off upon startup so it passes the visual OBD inspection.
If the Drive Clean testing started to use OBD2 scanners, an AEM would never pass of course since it can't provide an OBD2 interface... it's not inconceivable that the AEM "could" be produced to provide OBD2 but the only purpose would be an illegal one... :wink:
Not sure if that answers your question about the butt plug...

For what is is worth, I have a SOS supercharger installed. I am running a Fcon pro management sytem, kicking 420 hp at the wheels.
Working with Chris, the car had no issues passing our emmssion standards.The Aem unit can pass as well.
My advice, do even hestitate!!!
