Strangely, this is one turbo problem I have yet to encounter, and I'm
not using anything fancy -- just basic locknuts from McMaster (not even
stainless).  I only use them once, though.  Lots of *other* problems at
track days, but not turbo manifold ones. :)

I've heard speculation that the problem might be related to whether or
not the holes for the studs are drilled all the way through into the
manifold, such that if there's hot exhaust gases hitting the back of the
studs it makes things worse.  My CA 99 2-cat manifold has blind holes,
what are the others like?
