The difference is the Ecoboost does it by jamming a ton of air as well as a ton of fuel in at the same time whereas the diesel does it naturally without stressing the engine nearly as much. In the same sense though, that diesel will run out of stream quickly like the Ecoboost when the rpms climb which is where a big block gasser continues to shine pulling nearly to redline.
Not sure what you mean. Two V6 motors making 420 ft/lbs of torque at the same rpm are putting the same amount of stress on all components. That energy is transmitted to the crank the same way with the same forces. The smaller displacement diesel is actually stressed more than the gas motor in this example due to smaller components. Diesels have much higher compression and boost pressures than a gas motor. You mentioned not seeing many turbo gas motors because until recently, direct injection and engine control computers are fairly new.
