Attachment 7637I've been doing a lot of research, including why exactly I had a turbo fail. Thanks for getting the ball rolling with blackstone labs, I have leaned a lot. I'll go into details later but the summary is- coolant in the oil is bad. The sample after the gasket change still showed some and the next, even less. Put that together with over spooling turbos and low oil pressure and damage is likely. I sent my locked up dr800 to Pure Turbos in CA to rebuild because they have the ability to balance the chra at speed, which is more precise than most.
After talking to their tech for a while and giving him lots of info like engine displacement, boost psi, oil pressure and type, use of car, etc. I learned I have been over spinning these turbos a lot and way out of the efficient range. He measured the wheels and emailed me a DR800 compessor map. (Top of page)
The tech recomended Garrett GTX 2867R turbos for my application to last longer by staying in the efficient zone and spool faster (because billet wheel and ball bearing center section).
More power!!!

I'm an idiot and drove on that for ~1k miles. no crank damage which is why it ended up being so cheap
Wow, I didn't run it two minutes after the first knock!Quote:
