emissions

[lester]

Hi people here's a poser for everyone. I have a 94 mpi which is going to have a normally asperated 1.3 unit. I will put a cat on it, now i have been told that a carb engine with a cat will not go through emissions. The early mini's with cats and carbs don't need to go through a cat test but the later one does.Anyone know the answer?
Cheers for now Lester;)

went thru the mot ok without it, just took a bit of tweeking of the mixture to pass! :D not that i'm saying they run better without or anything :D

mine is a 91/92 and it doesn't have a cat and it got it passed on the emmissions with abit of tweeking but it was running on 3 cylinders at first in the morning untill it got used to it and now starts up fine on all 4 and even pulls away alot quicker and alot more nippyer

Couple of things

I gather you mean SPi on a a 94 plate?

Are you replacing the engine with a older block?

If so, I read somewhere that if it is from a pre-cat year then if you can prove the age of the engine that it will be liable to that years rules.

That's how people like morespeed get away with carbed up 1380's in modern shell's with late reg plates.

quite right, by law any vehicle on a K plate or later (all these are equiped with modern computerised emission control) will be tested on the lower emissions level, vehicles that have been modified to carb engines CAN be adjusted to the lower settings, which is not recomended.
The new MOT test now incorporates as you know a linked computerised system, therefore it is best to inform DVLA of engine change on the log book, so when you come to test the vehicle, the emision limits on their database will be altered acordingly to that vehicles engine spec. The engine change more often than not will need to be checked by DVLA agencies.
