Simon Posted May 10, 2006 Share Posted May 10, 2006 My supe failed it's mot today - 1993 j-spec tt with no cats. Failed on CO 0.6 I know that Chris Wilson published this link http://www.motuk.co.uk/manual_730.htm but I can't see anything there that specifically mentions pre 1995 cars and the emission requirements and cat requirements. Perhaps I'm going blind. Anyway, the tester will retest tomorrow if I can send him a link to vosa or dvla that shows that as it is a pre 95 import then it does not require cats and the emissions requiremnts are different than he tested for. Can anyone please help a rapidly greying and frustrated supra owner. post, pm, or email with links or otherwise, the tester will accept an email from me to any official documentation. I'm currently out of the country so can't be at the testing station that's why the tester will accept an email tonight from me. Many thanks.

supra dan Posted May 10, 2006 Share Posted May 10, 2006 afraid to say i dont think there is any info pointing to this, i had mine pass twice with no cats but the garage is computerised now, they put the engine number in and it says it needs the cats. tried another garage who did my mates evo 5 without cat and they said the supe does need it too.

Simon Posted May 10, 2006 Author Share Posted May 10, 2006 But how does the UK database tie up with a vehicle that is an import, I know they have the details from the V5 etc but it wasn't sold in this country so therefore I thought it had different parameters applied.

dilocruzy Posted May 10, 2006 Share Posted May 10, 2006 Has anyone had a j-spec tt MOT'd under the new computerised system that has passed without cats legally. I tried mate, its a 93 TT and failed!!! Needed only one to pass tho. Quote Link to comment Share on other sites More sharing options...
Class One Posted May 10, 2006 Share Posted May 10, 2006 Any car import or not after 1992 requires an emissions test afaik. The pre 95 import myth is just that. Quote Link to comment Share on other sites More sharing options...
stupra Posted May 10, 2006 Share Posted May 10, 2006 Its a pain in the butt this computer testing they do now. How good are these high flow cat's, an can we get them for the soop ?.

outatime Posted May 10, 2006 Share Posted May 10, 2006 Has anyone had a j-spec tt MOT'd under the new computerised system that has passed without cats legally. Mine did. He said there was no match on the computer and it came up as requiring the no cat test. 93 J-spec TT. Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted May 10, 2006 Share Posted May 10, 2006 have a chat with Greg at Turbofit. He's pretty insistant that a 1993 won't need the cats for an MOT (and he does know his stuff!) Edit same for me as outatime, mine went through on the no cat test last week Quote Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted May 10, 2006 Share Posted May 10, 2006 Any car import or not after 1992 requires an emissions test afaik. The pre 95 import myth is just that. you say that mate, but mine (an NA) i asked the tester at my MOT 2 years ago and he went through a book of cars that needed Cat test. So i give him chassis number and the number in the book didnt cover mine, so i didnt need a cat test. He said ring the DVLA for a definate answer as mine was 96, so he thought that was lucky. I was only a coupld hundread chasis numebrs below though If you do ring the DVLA, go through to right department or youll get no where Quote Link to comment Share on other sites More sharing options...

absz Posted May 10, 2006 Share Posted May 10, 2006 i had my car moted last week without the cats its a pre 1995 model. here's is what the mot tester should do. when the details of the vehicle are entered into the computer, it says MODEL type do not say its a 2JZGTE model but just type in default which is also available to do when the tester can no match the exact model of the car. it will then set the emissions on default which is a non cat test. (as long as its pre 1995) Quote Link to comment Share on other sites More sharing options...

Simon Posted May 10, 2006 Author Share Posted May 10, 2006 mikeyh, how did they set up the VTS system then, what vehicle model details did they use or default settings as no model existed? Do you know by any chance please? Quote Link to comment Share on other sites More sharing options...
Simon Posted May 10, 2006 Author Share Posted May 10, 2006 Let me rephrase the question: On what specs should a 1993 j-spec tt be tested for emission. Does it HAVE to have a CAT? Is it on BET test standards. Does anyone know please. It's been a year since I've been able to drive it and I want to get it on the road again so much.

Guest supra rob Posted May 10, 2006 Share Posted May 10, 2006 Any car that can be identified as august 1992 on wards import or not is by law to have a cat test, i have been mot testing for 2 years now and 2 months ago we went computerised and any mot garage that puts incorrect data on the system on purpose if caught will recieve points against there liscence you can ring any vosa helpline and they will tell you the exact same thing. A 1993 tt j-spec will have to have a cat test. Quote Link to comment Share on other sites More sharing options...
Simon Posted May 10, 2006 Author Share Posted May 10, 2006 Yes but what is a 'cat' test for a 93 import, can't be the same as for a 96 UK car surely? Is it a basic test or what, what flowchart is used to decide on the test to use. model and engine code both uk and j-spec are jza80 and 2jz-gte but the engines are different as we know.

Guest supra rob Posted May 10, 2006 Share Posted May 10, 2006 sorry mate but any car reg august 1992 onwards requires a co% of under 0.30% thats 1992 up to 2003, i wud put one cat back in, it only takes 10 mins and saves ya hassel Quote Link to comment Share on other sites More sharing options...
Simon Posted May 10, 2006 Author Share Posted May 10, 2006 OK I appreciate that but how can two engines with the same engine code but have different parts that could affect emissions be classed as the same engine, especially if one wasn't available over here. I accept that I will have to try and find a cat to put back in for the test, but I would still like to see the flowcharts and documentation.

Simon Posted May 10, 2006 Author Share Posted May 10, 2006 For the technically minded, what affects the co figure, engine temp ? engine speed? mixture? what? Quote Link to comment Share on other sites More sharing options...
Guest supra rob Posted May 10, 2006 Share Posted May 10, 2006 Well basicly any make of engine that comes out out the factory is designed to run inconjuction with cats and any cat you will find is designed to bring emissions down to below 0.30% weather it be a 1992 engine or a 1996 they all need to read and do the same job.

Guest supra rob Posted May 10, 2006 Share Posted May 10, 2006 For the technically minded, what affects the co figure, engine temp ? engine speed? mixture? what? co can be affected by a number of things 1 if you got no cats you wud be very very lucky to get it through the emissions, to a faulty temp sender so it could be reading colder then wat it is there for puting for fuel in, a faulty lambda sensor can higher the emissions if its not switching properly and this is normally adjusted by the ecu the list could go on Quote Link to comment Share on other sites More sharing options...
