DaveK 0 Posted March 25, 2007 Unfortunately my car is a K plate car registered on 30/8/1992. Im assuming the information below that i have taken off a website is accurate. Lookin at this it seems that K plates onward need considerably less emissions than those before K. Im building a rally car and so will need to be able to make the most of the emissions. Should i be looking at gettin a pre K car so i can tune it higher (even a B or C reg model)? Or will the emissions on a standard 1600cc (tuned as far as regs allow) be ok without a CAT for the lower emissions car? First used between 1/8/75 and 31/7/86 - meter test CO <=4.5%, HC<=1200ppm. First used between 1/8/86 and 31/7/92 - meter test CO<=3.5%, HC<=1200ppm. First used between 1/8/92 and 31/7/94 - advanced emission test (CAT) if its running on petrol when presented, to the vehicle specific limits usually around CO<=0.3%, HC<=200ppm and Lambda 0.97 - 1.03. Remember from 1st August 2001 a basic emission test will be carried out initially. Share this post Link to post Share on other sites
boombang 2 Posted March 25, 2007 As I remember, the emmissions is based on the older of the two out of shell and engine - but you'd have to prove the age of the engine. Share this post Link to post Share on other sites

Ryan 99 Posted March 27, 2007 (edited) What if the vehicle is fitted with a different engine?If the vehicle is fitted with a different engine from the one it was originally fitted with, then for emission purposes you should test to the limits determined by either the vehicle type or engine – whichever is older. For example, if you are presented with a 1995 car fitted with a 1991 engine of any make, you should test it according to the age of the engine. In this case, you need to do a non-CAT test, with limits of 3.5% CO and 1,200ppm HC. It’s up to the owner to prove the age of the engine or vehicle, for example with a letter from the manufacturer."

DaveK 0 Posted March 27, 2007 New question.....are all the 1.6 engines the same, i.e made before 1st august 1992 and dont req a cat? If they are the same that just solves all my dramas! cant remember ever seeing a K plated 1.6 Share this post Link to post Share on other sites
jackherer 543 Posted March 27, 2007 all 1.6s are pre 1992 manufacture and cat-free but some are registered after that on a K plate nonetheless. Share this post Link to post Share on other sites
