If you are specifically looking at turbos you have to look at the horsepower rating much more than a specific boost number. A turbo that makes 40 pounds of boost on a 2 liter engine would have to work just as hard to make 5 or 6 pounds of boost on the Camaro 6.2 liter motor. "boost" is just a measurement of the restriction to pushing the air into the motor. These LT motors are making a lot of power on just 5 pounds of boost.... 600+ horsepower worth of air moving on just 5 pounds of boost. That is a petty good flowing system. Hopping up a 2 liter 4 cylinder engine is easy, anything over 150hp worth of air is a gain..... you have got to get a serious turbo to feed this 6.2 LT that needs 450 hp worth of air without boost.... I can't see that this going to be done cheap.

Twin turbos rated 300 to 400hp each mounted directly on the exhaust manifold and sharing a common intake tube is the easiest way to get usable power. Ball bearing ceramic, titanium, small housings....all help reduce lag.... but add to the overall cost.
