Anthony Posted August 19, 2008 Share Posted August 19, 2008 Good morning, apologies digging through archives, but is it post 92 (K) that a Cat is required ? I am hoping its a bit younger Link to comment Share on other sites More sharing options...
Nick Pargiter Posted August 19, 2008 Share Posted August 19, 2008 Anthony I think it depends whether it was factory built or not. If it wasn't factory built then I think it is something like August 98, after that an SVA was required. For factory built cars I think it was about 92, 93.

Rob Walker Posted August 19, 2008 Share Posted August 19, 2008 With kit cars that were to be self assembled then if you purchased your complete kit before June 1998 you had 2 years to complete the build and it would still be emissions test excempt. If you were building from secondhand parts then you needed to prove that the engine was manufactured before 1995. As regards factory fully built cars I think it may be 1992 but I am not sure.

Support Team Shaun_E Posted August 19, 2008 Support Team Share Posted August 19, 2008 Depends whether it is kit built or factory built. A kit built car only needs to pass an emissions test if it is post 1st August 1998 (i.e. passed SVA). For a factory built car it is more complicated and will depend on the engine that is fitted. Assuming the engine is from the same year as the car then any post 1st August 1992 car will need to pass an emissions test which requires lambda to be between 0.97 and 1.03 - effectively requiring a CAT. Extract from the tester's manual is here. There are exceptions for some cars - see this flowchart here but I have no idea if any Caterham is on the exceptions list. If it is, then it MAY only need a CAT if it is post 1st August 1995. Searching the VOSA website can usually turn up the information but the full MOT manual is not available on there and the flowcharts are not on the motuk website. There are also exceptions for engines that were not designed to meet the lambda test and again a letter from the manufacturer may be required.

Peter Carmichael Posted August 19, 2008 Share Posted August 19, 2008 It is all in the 7FAQ All factory cars should have had catalysts post-'95. Most needed them since '92, with exceptions for the carbed cars. All Sevens since '98 have needed to pass SVA and need a cat. Link to comment Share on other sites More sharing options...

Graeme Smith Posted August 19, 2008 Share Posted August 19, 2008 All Sevens since '98 have needed to pass SVA and need a cat. EXcept those with NOS engines of course, i.e. 1600VXs Link to comment Share on other sites More sharing options...
