Cat is by far the leader in turbo applications, and I'm not sure if your talking about the new proclimb chassis, or the old M8 chassis.
I wouldn't bother with an old M8 chassis, they are fun but OLD, you feel like your riding a bathtub after being on the newer sleds.
The turbo pro is the funnest sled I've ever ridden, however you are correct in worrying about the motor and the motor problems have nothing to do with a turbo.
The fail rate with the 11's has reared it's ugly head, I haven't heard about any 12's so maybe poo has improved on something.
Ahhhh that's a little harsh. Maybe if you're thinking '07 and older M chassis. '08 to '09 got better yet, and a 2011 M8 is a pretty sweet ride. My Pro is great, but if I came across a brand new 2011 M8, I would take it over paying a whole bunch more for a newer sled. I love my Pro, it's really been awesome, but I loved my '08 M8 too, that sled was awesome. Maybe your bathtub comparison was from like an '06 RMK to the current model. That would be correct
