[urq] WX to MC-2 Swap - Oil and Intake plumbing

[urq]

I will try to keep the number of messages I put to the list to a minimum ...
and if anyone feels I'm sending too many messages on this don't hesitate to
let me know ... 

OIL: Today I remembered that I have two alloy oil pans that I've picked up
over the years.  One of them is a one piece affair ... part # 054 103 603C,
and the other has a main pan, an alloy extension and a plastic windage tray
... 034 103 603B, 034 103 627D and 034 103 623.  I'm thinking I can use the
latter part, but the extension might interfere with something.  Does anyone
know which models these parts came from?  Is anyone using the part with the
extension in a 10V urq application?  There is some sort of oil return line
fitting on the extension, I suspect it may come from the turbo.  I'm
assuming that I'll want to keep the single oil filter flange from the MC,
but I wonder if there's going to be an issue interfacing to the WX's oil
cooler.  It seems larger than the one from the MC ... but I do have both
available ... 

INTAKE: When I saw the MC airbox I was worried that I'd never be able to get
it to fit on the WX airbox ... but the plate bolted right up!  It also
appears that the top flange on the airflow sensor funnel is the same size as
the WX variant, so the alloy igloo should attach.  I'm going to have to move
some of the items that attach to the fuel distributor around I'm sure.
There are a couple air paths on the MC which would need to get worked into
the WX airbox.  One path is the IAC/ISV path, which basically allows air to
bypass the throttle plate when the engine is idling.  The other is the valve
which shuts off the fuel to the engine on overrun by bypassing the airflow
sensor plate.  I want to have the idle stabilizer function working, I'm not
so worried about the airflow sensor plate bypass.  If anyone has a solution
they worked out for these paths I'd appreciate hearing about them.  

I'm on to the electrical details now ... as noted earlier, I'm figuring that
I'll be able to determine a way to make it so that the car will run fairly
easily.  

A long time ago I got a copy of the MB service documentation ... I need to
dig it up!  I'm thinking that this with the Bentley for the 200Q will get me
the info I need to work out the details ...

I'm still hunting flywheel ...
