Well looked over at the gto forum on this board and read a bit about the aps goats.They seem to be working fine with same mits turbos. Tony.aka nineball has been running his quite a bit. No problems mentioned. No mention of collapsing inlet tubes on the gto forum. They look a bit different though from the f body setup.

looks like it was just a part failure...possibly not put together correctly. i dont see APS not doin anything...they've maintained really good customer service untill this point. they should step up and replace the unit no questions asked, upon inspection of the failed unit ofcourse.

that is exactly what it was
I will know more when I actually get it off of the car
I just hope that it does not have problems with the intake pipe getting sucked together because I intend to run quite a bit more than 7.5 pounds of boost
in fact it will not make that low on my car
I had the E-Boost ll set to 0 which makes it run off of the wastegate alone and it is making about 11 to 12 pounds pretty easy

You can swap out springs in the tial gates to anything you want. They come stock with 7.5 psi did you swap in bigger springs or have aps do it?
You can always run more boost than the springs but you are correct you can't run less.Boost controllers really only let your raise boost past the gate springs.

Could there be an element of mechanical damage somehow that cause the cover to fail ? which then lead to the compressor wheel/shaft failure ?
The Mitsi TD0x range of turbos are almost bulletproof. Ive seen them used and used them myself on loads of Subarus etc, and never seen one fail yet, even when you wind the boost up like mad.

I am just curious... when you found this damage, were heads of the bolts broken off in either the compressor or exhaust housings? (I mean the bolts that hold down the retainers.) If so, who installed the kit?
A few observations... I have popped a few charge air hoses on my Supra a few times and they don't look like your pics. Pic 1 and pic 2 showing the hole, it looks as if there was something that impacted the hose while under pressure, or there was a slice in the exterior and it weakened it possibly? It just looks weird.
Also, on an aside, in pic 3, is that a hose clamp holding on a rubber hose on the oil drain side of the cartridge? It looks like it makes an immediate 90degree turn? Wow. If so, thats a no-no bro.
Lastly, what did the turbine look like? Was it caked and covered with burnt oil? Any oil streaks on the inlet of the compressor? I am guessing no. The compressor exploding was due to the housing(s) seperating from the cartridge it looks like to me. Not the other way around. I have seen and relpaired several turbos that have compressors explode (Supra world, not GM) and not one has ever caused the housings to come apart.
Thanks.

A couple of 20Gs would have to work pretty hard to supply a good flowing 400+ inch motor. I'm wondering if it was a combination of a balance problem exacerbated by extremely high shaft speed?

keep in mind I am running a 403 not a 346
I think I am over powering the wastgates

with the E-Boost set to 0 it would make 6.5 pounds at the intake
on the same setting it is making around 11.5 in 2nd gear now
however on the PTS kit I was useing a 6 speed and now have a 4L80e and it probally loads the engine faster and may be helping it make boost quicker that it did before

I installed the kit myself
the exhaust housing has a V band clamp
the compresser housing has a internal snap ring and that is all
no bolts at all

Thanks.
the parts that are in my hand fell out when I pushed up on the compresser housing just a little
I think that the housing dropped down onto the spinning wheel and it went BOOM

Ive had engines with 2 x90deg bends, 5/8" diam directly after the turbo, and oil drains were never a problem.
Of course, if a hose is kinked, thats a different story, but a smooth 90...no worrys IMO.

I am not saying this is exactly what caused you failure, rather that a 90 degree bend right off the oil outlet can caused the coked oil to stay in the cartridge longer which can cause pressure surges and blow out turbo seals not to mention lack of fress oil. Talk to any turbo rebuilder and they will tell you that. What is supposed to speed the oil out of the turbo is gravity. Not pressure. The inlet orifice is far too small is have any meaningfull oil pressure when the oil reaches such a large hose.
Now in this application that may be your only choice. I dont know. Also, you may want to invest in some high temp steel braided #10 or #12 fittings and hose instead of rubber hose and a hose clamp for the outlet. I build my **** to last a long time and take abuse is all and I never cut corners with something like turbochargers. If you have questions, my rebuilder was www.alamoturbochargers.com.
What sucks is when a failure occurs it is hard to tell the cause. Things go boom and all you have left is lots of tiny pieces.
