I have a 2017 Mazda CX‑9 Grand Touring AWD with about 64k miles. My CSP11 coverage runs until around October of this year, and I haven’t seen any symptoms of coolant loss or head issues so far. As low as the miles are, I'm worried that the worst is yet to come -- or maybe I'm past the danger...

Does anyone have knowledge or a source showing whether the internals (pistons, rods, etc) are any different in the turbo motor vs the NA motor? Generally you use stronger parts to support the turbo, but it's possible they streamlined production and kept them all the same. But you would think...
