EURO emission class

[sweettom]

Hello!

 

I'ld have a important question. To witch emission class include the supra '93?

 

it would be necessary to know to my MOT in Hungary!

 

If my car is EUROI how could i modified to EUROII?

 

I've found some website:

Euro 1 AFAIK you can get it to 2 if you fit a "Mini Kat"

The Japspec JZA80 won't comply with even euro 1.

 

In Japan they test on warm engines and in europe after a 40 s warm up.

 

The eurospec JZA80 is euro1 and can be upgraded to euro2 with a minikat or a cold start regulator.

 

I have fitted a Japspec 2JZGTE to my MKIII Supra and I had to fool the temperature sensor with a timed relay and fit both the minikat as well as a cold start regulator and the bigger eurospec stock replacement catalytic converters.

 

But then it complied with euro2 and was a hair from euro3. (It came in at 1067 in CO - euro2 is 2200 in CO)

It's not only different test procedures in Japan, also the lack of the egr system and other components used (injectors, maps in the OEM ecu etc.) will make it unpossible to improve the Euro-class to "Euro 2". The Mini-Kat is of no use for a JDM supra.

EGR is not needed for Euro2. I have Euro2 on a japspec with upgraded cats (magnaflow california complient) and a modified temperature sensor (a timed relay that switches in a 200 ohm resistor after 4 s and forces the ecu out of the cold start tables). Then I fitted a cold start regulator making the car run 2500 rpm for 38 s.

 

I tested the car to 1067 in CO. That is half of the limite for Euro2. The only reason it didn't get Euro3 was a little too high HC.

 

So for Euro2 I would imagine just the cats and the tempsensor modification will be enough.

Yes Kristian, but you've done more than one thing to your engine. And then someone tested the car and you got an emission certificate.

No problem. These kinds of emission test usually cost ~1700-2500Euros. And I doubt the OP is interested in spending these amounts of money.

What I wanted to point out is the that the JDM versions don't comply with the EU ones and therefor a thing like the MiniKat won't work.

At least if people involved act according the regulations...

I also know people that drive around in Germany with wrongly achieved Euro-classes which could lead into problems (tax-fraud) ...

[Kristian_Wraae]

Well I think that is what I wrote.

 

If the car is Japspec then no EURO of any class unless modified and testet by TÜV individually or as they told me if someone does the same modifications as I have done they will certify euro 1 to that car since my car did euro2 (but that will only be mkIIIs with a JDM 2JZ-GTE and the same modifications as I did)

 

If eurospec then Euro 1 or if they accept the german papers for the Walker mini-cat that can be bought on ebay then possible upgrade to euroclass 2.

 

The fraudulent papers that circulate were also sold to me (for 500 euro....) and they were rightfully not accepted by the danish authorities. I wasn't told by the company that sells the papers that they were fraudulent. But I later found out that they had modified that car with an air pump pumping in air before the cats, new euro spec cats and a complete remap using bioethanol.

Btw the test costs 1000 euro in Hannover. And I think it is not too much compared to what we pay for our cars and the modifications that some do to them.
