I'm not sure it would be practical, and I AM sure it would be expensive to build and fit in a car! A single turbo would be more practical, and I wouldn't be surprised to see that in Trail Blazers before long, maybe even in 1500 series trucks. The six has the low end pulling power (torque) without the turbo, the turbo supplies the mid range + power. A turbo twin cam, variable timing I-6 should deliver close to the same performance as the latest small V-8s with better economy.
