Which model to buy.

[JamesC]

Turbocharging is nice to have especially when one engine quits on a hot humid day, particularly if there is weather/terrain below you that you don't want to descend into. Trade-off weight, more likelihood of needing a top overhaul, and overhaul costs of the turbo/waste gate/controller.

[general]

It's only money $$$$$$
The turbo will cost more $$$ all the way around.
Just like gas via diesel pickup truck
