Hi All
If I fitted a Zetec engine from a post '92 car with no cat, how would the SVA inspector know. Do you have to prove the age of the engine. I plan to use most parts from a Sierra except the engine

Hi
Yes he will know, he will ask you the age of the engine!

In sweden we can pay a onetime fee of 7000 SEK (780 Euro, £500), then we don't have to have any emissions reducing devices. However £500 is a big part of a locost budget, so it would be nice not to have to pay that fee. If we use a 3-way catalytic converter we dont have to pay that enviroment fee.

My qusetion is: how difficult is it to add a cat? Or bring the cat from the donor engine?
In order to get the cat to operate properly thier has to be som electronics to regulte the air/fuel-mix.

As you say there are some electronics connected to the cat,loads of electronics to be precise,best bet is to take the whole loom and a workshop manual and work out what you need , a lot of wires are resisted and need to be the original wires and the original length or it wont work properly
good luck!

Thanks theconrodkid, I'll keep that in mind when I do my research.

Has anyone successfully fited a cat? If so, what problems did you encounter?
