I just had my TA-49 Turbo rebuilt and it had a hard failure. Started to blow oil into compressor side and compressor wheel contacted side. This turbo did not even have a hundred miles on it. This failure happen on the way home from the track after four runs. Anyone have any idea what could have caused this and what I could do to prevent this again? The rebuild cost me 425 bucks and I feel that it should have lasted a lot longer than 100 miles.
Rebuilt turbo failure within 100 miles

Did you prime it first? Who rebuilt it?
Id be willing to bet the stall and shut offs at WOT are the culprit. Loss of oil pressure while spooled will cause failure almost instantly since the thrust is very high as the compressor is pulling the air in.

Good call Bison, that turbo's probably spinning over 100k rpm and then it lost oil pressure and I'm sure oil runs off the shaft super fast at those rpms.
Don't shut down the car after any runs until the cars back to a normal idle, can't do much about the burn out stalls but check into your chips Decel and you'll probably have to feather it and then ride the brake to keep it alive for now.
Might be time to go to a bigger turbo, rebuilding the 49 twice kinda blows. I think you can do a 62 with the small shaft TA comp housing.
