everybody scared of turbocharger, yet nobody mentions that they are simple devices that are PROVEN in every single 18 wheeler that runs down the road. The turbocharger isn't the problem it's the owners that are usually the problem.
the 2.7 makes more torque than the 5.3 down low.
turbo engines were and still are used in aircraft too, so by themselves they are not less reliable.
that is the way automotive engineers are going, smaller displacement with forced induction. This way they can achieve excellent fuel usage characteristics and excellent emissions characteristics that satisfy the US government. Secondary benefit, when you want torque, you can have it. Just mash the pedal.
There is some different maintenance that should be done (more often than the book says....), and shut down needs to be a little different as well. Need to let stuff cool off a little before shutdown.
Then you have guys that can't leave stuff alone and start modding them. Turbocharged engines tend to respond a LOT better to mods and that also often leads to failure-not because the engine can't take it, mostly because tuners don't have the same kind of knowledge that OEM's do. I know y'all gonna argue about that....go ahead...ain't hurting my feelings.
