changin middle section on a turbo?

[EuroGSTSpyder]

Well I bought a Big16G and installed it.However I broke one of the bolts to teh oilreturnline.When trying to get it out even the tool that we used got stuck in there and broke so I cannot bore it out now either.I fixed it temporarely with one bolt and a special hydraulic compound so its there and sealed right now but I cannot run like that when i go higher on boost and all.
So my q is this:
Is it possible to change just that part of the turbo so I can get the oilreturn line done as it should be? I will leve it to a shop here that build turbos for disambling and rebuild/flowprep/balance...but I need a section of a Big16G to do this if possible?
Anyone got a smashed Big16G over? *smile*

Yikes, busted the ez-out as well? Bah. You could go after it with a small grinding or carbide point on a Dremel, but it'd take forever. Unless you just got lucky and put enough vibration into it to shake it loose.

Then again, the lucky don't snap off bolts to start with. Bah.
