John,

I called Alan and had him send me a TV 8101 complete turbo and then sent him my old one. If you'll call him monday, and want to pick it up at their place, he can have it there.

John, that is a TV 8101 with the A/R 1.84 it is for a 92 series,the 92 series parts number start with 51 FWIW.
The turbo change alone is not going to help with the fuel mileage when changing turbos you pay a price some place on the torque range for instance a fast spool up you will have the torque and no smoke at the low end then lose it on the top end of the range. 
Not knowing what injectors you have that may be the best turbo for you
So where do you want the power low, middle or top.  

good luck

On digging down with the help of Cliff, Richard and Kevin i have found the following..

My 8v92TA Has a turbo as follows

TV 8101 with the A/R 1.84  My friend that had the engine rebuilt is not sure but thinks it around 485 hp.
Right now I do not get any smoke (that you can easly see), so do I stick with 1.84 or go to 1.60 which may give me a faster wind up and better milage.

They make the following turbo,s

TV 8101 with the A/R 1.60 (this is the midrange turbo) and,

TV 8101 with the A?R 1.39,

Frank,

I heard pinging sounds coming from the Turbo as the engine was switched off and the Turbo slowed down. I removed the air intake and spun the turbine blades. If I pulled it away from the exhaust housing it would spin with no noise, but if I pushed and spun it towards the exhaust clam shell it was making a scarping sound. When I did take it apart I noticed that the clam shell clamp next to the exhaust was a little loose. I pulled the complete Turbo out, no vains were damaged with the exception of the tips that had been scraping the ID of the exhaust lam shell. when you move the impeller up down and sideways there is definite play. So i feel like I was blessed to find it before it did any damage.

I am even more blessed to have Cliff, Richard and Kevin,s help to walk me though what to look for and how to do it and were to look for parts..

Dallas,

Great to hear I little input from you, now I know you are feeling better and up and running.

You probably have not noticed that the Turbo problem just started last week.

When we talked several months ago I had no idea what type of injectors,what the engine is timed to and I still dont.

I am/was looking for better MPG 5 or maybe 6 is just not enough. I was hoping a diffrent turbo will improved my MPG (as I have this one out and have to spend the money) might just be the ticket. i would love to brag about 10 MPG would you not. I know from past experience the old 03,s or 04,s may get 7 MPG at best.

As for the 4.5" X 9" hole in the side, its larger than the 5" OD pipe that goes from the air cleaner to the Turbo.

John I'm posting a complete 8V92 reference list..   You can see your turbocharger listed as a TV8101 with a 465010-0003 part number or 5102117

John, here is the build sheet for your turbocharger.    I received your message this afternoon.  If you engine is really at 480HP, then you might really want to keep the larger 1.84 A/R.   Please realize that the A/R  should not be compared to another "out of family" turbocharger.   It's not a apples to apples comparison when you look at the larger TV85 series.
