< They do not. BTDT. Turbo EMs run _way_ hotter than
 normal premium quality EM nuts can tolerate. It's amazing how many very
 skilled but non-turbo oriented wrenches will lead you astray on this one.

    yes, but its so tempting.  These cost about $3 each at the dealer (you
need 10), and the big 12mm nuts cost $8 each (you need 8 to do bolt the 
turbo
on right)!!!  These are all made from titanium, thus the cost.  You are in
over $100 by the time your done here!  Anyone know of a cheaper source?

hmmm...  installed a new 2 piece em a few months ago and used the copper EM 
nuts to avoid the "frozen nut" syndrome that caused the final bridges of 
uncracked stud material to break during the EM removal process (5 broken). 
 Can someone cast some light on what happens to locking copper EM nuts in 
this case?  I've not seen anyone discussing failed nuts, just broken studs 
from high leverage and heavy exhaust system components hanging off of the 
head (plus motor mount problems, etc.).
