Ill be building a 1293 engine very shortly, now i know that the MOT tester uses the age of the engine to determine what sort of test they should be using but how do they determine the age of the engine? do they go off the engine number or would i have to prove the age of the block myself? thanks

was the engine in the car at the last MOT ?

As far as i know it the age of the car, not the engine.......

It's done on the age of the engine, but it works both ways - if you put a 2010 engine in your mini it would have to meet the 2010 emissions standards

no

engine or car what ever is older

this is why you can fit a modern engine in a classic car and get away with out running the fuel injection and keeping the cat in the exhaust

Im an mot tester, and ive always gone on the age of the car, which is what the emissions machine asks me for, not the engine age, in fact theres no option for engine age.

Id also like to see how someone can properly prove the age of an engine to me too.

Right you are;

http://www.motuk.co.uk/manual_730.htm

Vehicles Fitted with a differnt engine

Test according to which is older, engine or vehicle.
e.g. A 1995 car fitted with a 1991 engine (of whatever make), test to 1991 standards for emission purposes.

Note: The onus is on the vehicle presenter
to prove engine age.

It's which ever is older, however, it is the responsibility of the owner to provide proof of engine age, just saying it's the engine out of an older vehicle is not evidence enough, the best evidence is the registration document of the donor, detailing the engine number and age of vehicle.

My engine decoder, coupled with information from the Rover parts catalog has been used as engine age evidence for an SVA.

The last option is an engineers report.

However, a rebuilt engine is no longer the original engine, so cannot be considered as "old".

Ah, but doesn't matter if the car is older

At the moment i have a standard 1275 SPi engine in the car, but when i replace with the 1293 carb unit i'm just confused as to how you'd get through the MOT.

You wont, unless you know a tester which won't mind loosing his licence if he gets caught.

Hmm...may have to rethink this idea then haha

Plus the companies licence to do mot's too, and possibly appearing in court.

Mot testing is so frustrating, especially when friends come to you, expecting a guarenteed pass, which i cant do. Im not risking my job, (plus everyone else i work withs job), house, car, livelihood, etc just to save someone else a few quid getting theyre car to meet the minimum standards that an mot is. Yet, theres plenty of dodgy testers out there willing to.

Quite easily, using the engine number.

If the engine number/type doesn't match that in the database then it can be proven to be a mismatch. Theoretically as soon as an engine is rebuilt/reconditioned using larger bore pistons etc. then it should have a new engine number assigned to it, that doesn't always happen though (in fact, it rarely happens with homebuild engines at all).

Anyway, the vehicle has to pass an emmissions test to the age of whichever is oldest, car or engine.

What i cant understand is how people who put engines such as vtecs and r1s in get through the MOT? surely if people can get through MOT's with those engines in a mini then i could get through one with a bored out a series?
