i am sure my engine already has 1 webber carb, and an ecu, and a CAT.... and an MOT
Sorry babe, but I think your confusing injection with carbs.
Carbs are like having a tap left on with fuel coming out with very low fuel pressure needed and is adjusted very crudely. They are set to over fuel slightly to get power out and as such is very hard to setup with a cat on the car as over fueling wears them out.
Since we all have to have cats on the cars to pass mot, car makers have to get the fueling spot on so not to wearout cats.
This is why every car has some form of fuel injection these days. :yum:
I am 99% sure that all cars with carbs dont have cats on them (happily corrected if someone has an example

) however if you want to go via carb route then get the inlet manifold from the fiat panda, alternatively find out how the pandamonium was done as that had twin carbs too.
Webber are famous for making carbs but they dont make them anymore (no car makers buy them) they can only supply refurbished units however they do supply a lot of today injection systems (perhaps this is what you mean?

)
Fitting carbs will sound wicked, will get power out of the car but not as much as a remapped injection system and will cost a fortune to run as it is over fueling all your petrol away...
Setting up a non-standard carb is all about filing/rubbing/sanding down a brass pin so it changes widths in all manner of none linear fashions. This pin is called a jet, or rather it controls the jet opening. Any non standard jetting is often limited to a fair old range of these pins. If you can find someone who still has such a range and a range that suits your car set up, the rest is easy. Its a black art mastered by only a few, if you are taking things seriously. But please note the carb's man dream is one carb per cylinder, forget the difficulties of mechanically linking all together so the carbs work together. (Guess you know the problems uneven firing/compression/mixtures can produce at the finer end of things, if your being serious). NB some natty little Jap sports cars had one carb per cylinder.
The old story was to have one carb? But Carb men need twin carbs. And dream of one carb per cylinder and the next step every carb man wants to make is injection......
Unless your Micheal J Fox I wouldn't try to go back to the future..:devil:
Lol - i did that without taking a breath!!
