Engine conversion and mot emmisions question

[tidyclio]

Hi, Just about finished putting a 172 enigne into a 1.2. I would like to get it for an MOT on Friday and was just wondering if anyone can tell me whether or not it will fail on emmisions as it is originally a 1.2.

Are the tests set by which engine it is or just the year of the car?

Any help appreciated.

doesn't matter, if it passes it passes all car regardless of engine have to pass a set limit

Thanks for the answer. Fitting the engine in the next couple of days just waiting for some bits. Got the auxilaries bolted on just can't work out which bolt should be on the bottom of the tensioner and whether it should fit inside the bolts hole or sit on the outside by the washer!

Hope it's ok to give you a bell still if I run into problems.

Thanks
