My experience is this... (riding 30-40 days a season in Revelstoke/Golden area's)
2011 & 2012 cylinder skirts are thin and once the piston wears and starts slapping they will crack that skirt off and it's all over. 2013 & up have a beefer skirt which I beleive solved that issue. I was usaully changing motor mount bushings once a year, as they wear out faster due to the added torque from a turbo. Easy fix, takes 15 mins to due all four. Installed SLP engine brace and Boost-it engine stop which seem to help extend replacement. Exhaust donuts needed to replaced twice a season too. Seemed to go through a few TPS sensors aswell. Ended up always having to carry a spare and tools to set it. I've always dumped 250ml of oil in each tank of fuel to help lubricate the reeds & crank through the aux. injectors. As mentioned above, good fuel is key ! ran between 6-10lbs boost. Originally ran nitrous on this sled, and sure noticed the weight of the turbo hanging off the exhaust side for the first couple rides. Think I weighted it at 30 lbs.
This was on a 2011 Pro 163 Boost-It w/a kit w/ garrett 2863 - C3 belt drive - stock head with 6600 kms. I've snowcheck a new 163 x 3 and will be riding stock this year. My Turbo days are over, sick of wrenching and fixing my $hit for the last 2 seasons. I personally think I floated Polaris' stock market prices for a week last winter with my parts orders LOL.
