John,
really sorry to hear that.
More
like a major set back. I suggest you re-build it your self.
Can be done by a first timer in a few days. Since you won't have much
cleaning to do and can re-use most of the apex seals, it will cost only a few
hundred bucks in gaskets, supplies, tools and a single replacement
seal.
If you
want, you can ship your new turbo to me for save keeping (heck, you're only
going to destroy it too). :-)

Well, they say a picture is worth 1000 words.
In
this case the picture is worth about 1000 dollars. :(
The
compression tester prints a tape showing the compression pulses. On rotor 2 it
looks fine. 3 peaks for every cycle. On rotor 1 there's one peak, one tiny
blip, then nothing. I took off the exhaust manifold and, sure enough, two of
the seals are shiny and spring back about 1/16 inch when you press them
(hard). The other seal is intact, but not shiny and only springs back maybe
1/32 when pushed. It IS moving, so it's not a stuck seal - sounds like the
side seals are gone. We'll know more when the Mazda guy gets the engine comes
apart......

(just a minor set back)
