During a recent annual on my 1980/1992 231 Rocket I noticed the turbocharger has dent in the housing unit and will need to be repaired(?) or replaced. Anyone know who can help me with this or can sell me a turbocharger?

Hello all, long time lurker, first time poster. I am planing on buying a M-20C thru M-20F hopefully in the next month or two inventory on the market willing. I've been looking for the past year since a little before a deployment though the deployment and the two extra months of deployment, thanks for nothing corona virus. I understand the differences between models and don't rally have any questions save for one. What is the lowest fuel flow in GPH can you cruise in a TN IO-360? I know how the turbo works, and what it gives me thanks to a few post on here and their links to great AvWeb articles for more in depth information. Background: My mission primary is to build hours over the next year or two so bringing GPH down while cruising is an important aspect of the plane search (not the only aspect otherwise I'd be looking at anything with a C-85 engine.) With a NA IO-360 I know I can cruise at 6.9 GPH or better. But what i don't know is if I get a plane with a Rayjay TN and a manual waste gate control will I be close to that as well? My thought is if I chose to not use the boost and open the wastegate i should get close to NA GPH, though with the impeller blocking a bit of the intake and the turbine in the exhaust flow I'm thinking some efficiency will be lost and everything being equal the Turbo engine will require more GPH, but is that .5 more or 5 more? My guess is less than 1? having read all the posts on this forum I know that 69% of the responses will say "Mooney zoom" and "WOT all the RPM!" and while I love the enthusiasm and will join you doing that from time to time, I'm kind of looking for the practical low GPH setting in a Turbo. Yes I also understand the temperature sensitivities of the system as well in regards to TIT, EGT, and CHT. Lastly, with the turbo working boosting away what kind of GPH does one typically see in the flight levels, like FL200? Proof reading this, I feel like I could word things a bit more softly or diplomatic, but I'm starting to see cross eyed and need to go re install my 9 yo in his bed so apologies if I am less than as coherent as I should be, and thanks to all in advance for knowledge I know I will receive from this fine community.

I have exhaust leaks at the points showing on the attached picture. Can anyone provide part numbers for the gaskets here. We can likely find the one at the v-clamp but the Mooney parts M20M manual I purchased doesn’t have the turbine inlet gasket shown.
