Wrong. More parts = more opportunities for failure. It's not rocket science, but a person needs better than average intelligence to understand it.
More unique systems is the real driver friend, not more parts. You can't seriously think that having 100 bolts holding something together vs. having 99 bolts holding something together would make that something more likely to fail, can you? That would be insanely stupid. And you're not insanely stupid right? Maybe just a little slow?
Turbos also generate a lot more heat, and heat is a killer. Further, your mains/rods/pistons are all under a lot more stress. So the bottom line is that your whole argument is and always has been a joke.
Tell us again how smart you are.
