Help guys,
My turbo has a broken fin on the exhaust side that is causing vibration and fuel all over the toad. I have a 8-92 turbo # 8101,440hp. Can I put a 475hp turbo #8511 to make the last 1000 miles home,which I have, or limp home with what I have?

You sure can Richard will be a little more smoke on take off but it will work that turbo is used on a bunch of different hp rating only the A/R is different Good luck
Richard your part number for the 8101 from DD should be 5101513 with a A/R of 1.60 FWIW that turbo was used in seventies for the 8v92 TA green block. with the raw fuel I would be concerned.

The TV8511 is a larger turbocharger>is it from a Detroit? Do you have the actual part numbers? 1.23 A/R on the exhaust turbine housing side?
How did you lose a turbine blade? Was there work done on the engine recently? If you continue to drive your bus, you will have a similar situation that Sean has recently had.
Do you have time to rebuild your existing TV8101? The TV8511 is a nice turbocharger depending>post the part numbers.

Based on extremely recent experience, I would advise against driving 1,000 miles on an imbalanced turbine. You will be better off putting the other turbo on, or, better yet, get a new turbine put on the one you have.
Also, I would make a best effort to figure out how the turbine got damaged before putting a fresh one on. If you are spitting bits out of the manifolds, you need to fix that first.

the turbo is a garrett tv 8511 p/n r8927027 s/n v 5501 bd107 and came off 8-92. this was on the inlet- m 24 a\r .61 b.o. the exh just had garrett on it
The reason it lost a fin was I dropped a valve in cleavlen, ohio. I was towed to canton, ohio to a detroit dealer where a head was replaced engine cleaned out,etc. They didn't have a turbo to replace mine and of course on a friday afternoon. Said I could wait till tuesday or so to get one or drive mine, so we left. this 8511 has no play so I'm going to put it on.
Thanks

Rd;
The number will be stamped inside the exhaust flange. As Zero said it is a bigger turbo and will move more air, you can change the hot housing ( H H ) to help with your low end and take away some of the smoke. You can also take the throttle delay off and go to a fuel modulator. What size air filter do you have, 7" or 8" 7" is fine for 440hp but 500hp.
