neo2810 Posted October 25, 2010 Share Posted October 25, 2010 I've had a good search, and this seems to be a largely unanswered question where the NA's concerned. My car goes into AAS on Wed for a new induction system, performance manifold, double decat and new performance exhaust. It's then due it's MOT mid Nov. Mine's a '93 J-Spec so as I understand it, it will be tested as a decat car and have to be below 3.5% and 1200ppm. How many of you have successfully passed the emissions test with both decats?

Aero-M Posted October 25, 2010 Share Posted October 25, 2010 You can get a mot a month before it's due to expire, so as it due mid nov do it first then you'll have a year plus a few weeks. As far as I know it was 1993 for uk cars and as Fiz said 94-95 for imports that cats were required Quote Link to comment Share on other sites More sharing options...
Supra-Brett Posted October 25, 2010 Share Posted October 25, 2010 Dont worry, every time i MOT the inspector cant find the exact model as its an import, and hence they use some massive default readings for CO etc. Basically, it would be almost impossible to fail.

gjp Posted October 25, 2010 Share Posted October 25, 2010 Also the na engine number is not in the mot book so won't need an emissions test anyway. Or so I was told Quote Link to comment Share on other sites More sharing options...

David P Posted October 25, 2010 Share Posted October 25, 2010 Copied from the 'stickie' at the top of the page re. MOT. "One useful piece of advice which is probably the biggest is for you NA guys... So far, going by the emissions database, there is NO such thing as a NA supra. The database only lists a 2JZ-GTE engine, (for the mkiv) so all of you that are worried about having no cats fitted then don't! Yes you will fail the initial 'BETS' test but it follows into a full CAT test, in which a 2JZ-GE does NOT exist, as it wasn't a UK car, so this puts it into the category of being a 'non-listed' car, as such the 'default' limits are standing idle of 3.5% CO and 1200ppm HC. I have passed a certain members car, using these limits (no names given) and it is FAR from standard and it passes every time. As well as there is no rule stating you MUST have a cat fitted. If you can get your CO% to below 0.2/0.3% at 2.500-3000 rpm and HC to below 200ppm your fine! I also know of a new 'rule' that is out regarding exhaust noise, in which 'anything that is louder/noiser than what is regarded as a standard noise level' is now classed as a fail. Which to be honest is most of us!" Interested to know what power gain you achieve. Quote Link to comment Share on other sites More sharing options...
