Looking for advice on turbo life span.

So here's some history, my spyder has had a T28 since i bought the car over 2 years ago. After the old 7 bolt spun bearings and I bought a 6 bolt, I had Justin rebuild the turbo, was needed, and it performed as great as he has advertised. Since then, I've been reeducating my girlfriend on how to drive manual and such and it has taken a toll on the turbo to where it needs another rebuild.

So that being said, how likely is it that the turbo will hurt my engine? I know it needs repair, but I'm just buying a new turbo when I've saved enough up for it. But until then, what can I expect aside from reduced power? I'm just looking for people's experiences with this subject, not I should buy this or that, just experiences and maybe ways to prolong the turbo from failing or destroying the engine.

Ive ran my t28 since 2008 with 5-6 track days per year (100 passes) and lots of heavy foot driving..still going strong..how did she kill the ol turbo?

It was all the stalling out that I believe ruined it. All the hot oil not being allowed to cool down before shutting off the engine. That along with the inconsistent driving associated with learning to drive manual.

Turbo life is directly related to oil flow and cleanliness. If either one of these are interrupted for whatever reason, the turbo will fail almost immediately.

I've built new turbos for folks that have failed in days because they were receiving dirty oil.

And I believe my shaft play to be directly related to interrupted oil flow due to the girlfriend's stalling. Because of this, can that have a negative impact on the engine besides power output? Such as bearing failure of rod and crank journals?
