Every turbo is going to have failures and i dont care who makes it and who owns it.
IN our world, of diesels, we ask alot of turbo chargers because we are ususually pushing them to a higher pressure ratio then most manufactures originally designed them for, billet wheels are big in diesels because of that, they can get rid of most inperfections in the metal before the wheel is built thus allowing for higher shaft speed. But even then billet has imperfections and limitations.
The best thing we can all do is make sure that we have as much info as possible, boost, back pressure, air inlet pressure helps a ton when trying to figure things out when they fail. THere are also things like oil quality and temperature that arent quiet as easy to monitor and keep track, and determining that failure usually comes down to what the turbo builder finds upon dissasembly of the turbo. THings like burnt oil on the shaft, high wear on thrusts ect, My honest opinion is IF you do have a failure keep in touch with the turbo builder on cause of failure, and have them show proof of what they found. Warranty or not you should know to help prevent it from doing the same thing.
The 366 apears to have some failure rate, but at the same time we have no clue how many units are out there and how many have actually had issues, same with the 76/82s as mentioned.
