Superchargers are far easier to install. You drop them on top of the throttle body and tighten a pully around the crank. A turbo has to be custom made to link the exhaust to the intake, which would be difficult to connive in the engine bay in the Crossfire. You'd need an entirely new exhaust manifold, header, and cat-back, along with a completely redesigned intake route. Plus superchargers put less wear on the engine because they only boost when your throttle is wide open.

If you want power you're going to have to lay down a LOT of money. $1,000 won't even get you 20 horses. $6,000 and you may get something going. $15,000 is when you car will start to go much faster.
