The answer is here: http://forum.fordsierraclub.co.uk/vi...=MOT+catalytic
"For emission purposes vehicles are tested against details shown on the VIN and not the registration plate. Vehicles fitted with a different engine are tested according to which is older, engine or vehicle.
Catalytic convertors were introduced from 1st August 1992 and are compulsory after 1st August 1995. Vehicles first used between 01/08/92 and 31/07/95 are only cat tested if there is an exact match (re engine code) in the analyser database or in the Inservice Emissions book. Vehicles first used on or after 01/08/95 are cat tested using vehicle specific limits if there is an exact match. If there is no exact match it is cat tested using default limits, CO<=0.3%, HC<=200ppm"

At present no car requires a cat for the MOT as long as it meets the applicable emissions requirements, that will change from next year where a cat will be required for some cars.
To answer the original question, for a car first used between 01/08/86 and 31/07/92 the emissions limits are 3.5% CO and 1200 ppm HC, so no cat required.

Jan 2012 any car which was fitted with a cat from new will need it to be fitted for an mot, vsi on the mot computer will tell the mot tester if the car in question had a cat from new.
There are loads of new things coming into the mot test next year and a lot of the old stuff dropped out,
