This is true, naturally aspired engines lose about 3% for every 1000 feet you go up in altitude. But the bigger motor will still have more hp then the turbo'd motor in this case. At the same altitude. This is only because this motor is twice the power of the other. If you are talking identical motors then turbo is the only way to go.
