OK - I've found a likely donor vehicle for turbo-connecting parts but it's an 806/synergie/ulysse, rather than the expert/dispatch/scudo I actually have. THings are nearly the same, but:
The exhaust manifold on these doesn't just go to the turbo - it has an extra spigot for what I believe is the EGR system:

This seems to show the system that connects to it:
What on earth is all this stuff? And what are the other bits it connects to (e.g. what does pipe 13 connect to, and what are the two greyed-out things the small pipes connect to? I don't recognise any of these, and suspect I don't have them.
What are the pros and cons of EGR?
So, my options are:
1) Use this manifold and make a seal to bung up the extra spigot. Not sure how easy this would be. Just welding it shut should do the trick?
2) Get all this EGR stuff. Might be good for my emissions? What other parts does it imply (e.g. do I need a cat?, different pipes?)
3) Go and find/buy the correct plain manifold (neatest, but I still have to find one or cough up to peugeot). 6 scrappies couldn't help today, and no responses from two internet parts searches.
Which would you do?
One more question - Does having a cat exhaust imply the need for the EGR system to protect the cat?
how does EGR system work?

I recognise these bits from my BX19 diesel.
This EGR system (cant remember what the abbrev is for) was a legal demand on Swiss & Swedish BX diesels in the late '80's, and some of these BX diesels ended on the DK export market.
Basically the EGR system takes some of the exhaust and recirculate it into the inlet - to bring down the pollution.
Hose 13 interconnects inlet & exhaust manifolds via valve 10, which in turn is vacuum operated by the rest of the stuff - including a special ECU 16.
Defo no fun to retrofit. I'd certainly blank off the valve 10 hole on the manifold.
I'm not sure this EGR system is needed in the UK - at least on this yearmodel ?

If you don't already have it fitted, you won't need it as the UK MOT emissions test is done by the age of the vehicle rather than the age of the engine thats fitted to it.
