Just updated the build thread, cross posting for those not really following our Swedish adventure. 

We lost a small hold-down off the cobra pipe.  Looked everywhere and fished around with a magnet.  Was it laying on the radiator support?  Had it landed near the turbo?  Was it on the ground? 

When the turbo began making an odd howl, our worst fears were realized: it had made a nothing-but-net shot into the hose port and was riding the perpetual spin cycle on the “in” side of the turbo.  Oops. 

[As has been pointed out, the Cobra side is “in”.  Stupid me.  Who lets me work on cars, anyway?]

Here's the result:

 

For reference, this is the exhaust side of the new turbo:

 

Lessons learned: be like the pros - put a shop rag in every open thing while you're wrenching.  Also: this Mitusbishi unit was tough: it never smoked, it kept making boost, and the shaft bearing was still tight even after the involuntary machining.

Good thing it was the hot side. Sucks when you lunch a motor by fod'ing it out.

You sure that is the exhaust side? To me, that strongly resembles the intake side of the compressor and the v band clamp that attaches it to the "king Cobra" intake pipe.

Knurled.

Er, yeah.... exhaust sides are always part of the shaft, the compressor wheel always bolts on.

 

And the only way you are dropping a fastener into the hotside is if you have the turbo off of the exhaust manifold.  (The axial end of the hotside is the exit)

You’re both right. Cobra side is in. Post edited, title still wrong.

Oh that's no fun then. How much crap ended up in the intercooler?

I just sort of assumed you had the downpipe off.

All of it?  We never dropped the intercooler but found bits of what must have been vanes.
