Hopefully DA222 has the engine out ... so we know what got screwed up with the clutch ... I'll check by later today.  I have a line on a flywheel in Ohio, still hoping to find something local.  

I think I've got the wiring interconnections to make the engine run figured out ... there are only a handful of connections that need to be made ... and that will even make the ISV functional.  

I have the fuel distributor plate from the MC bolted on to the WX airbox cover.  The igloo fits right over the MC-2's airflow sensor funnel just fine.  I haven't spent much time figuring out the fuel plumbing, but since the fuel distributor seems to have the same fittings in the same locations, worst case I can swap the WX lines onto the MC FD.  

Since I'm using the MC's intake manifold and the urq intercooler I'll need to find a place to attach the intake air temp sensor.  Anyone have any recommendations?  I have an intercooler that came from an urS6 which looks similar in size to the WX ... and it appears to have a port for the temp sensor.  I think I'll take it along just to try it out.  

I'm having secong thoughts on the oil cooler.  The MC has different attachments, so I'm thinking it might be better to try to mount the MC cooler in the WX location.  Any BTDT on whether or not it makes sense to try to mix and match?

Probably the biggest outstanding item is the intake plumbing.  What will I use to connect the outlet of the intercooler to the throttle body?  How am I going to plumb all the vacuum lines for all the functions that need them ... ISV, WGFV, Crankacse Vent, vapor recovery, etc?  I found a drawing in the 200 manual and one in the IST and will see what I can noodle from them.  Here again the goal is to make it look like the drawing on the hood ...
