Given the price of the turbo and supercharger kits, I’d consider going with an LNF instead. A friend here recently got a new (possible remanufactured, but this engine was clean inside and out) LNF, complete with turbo, for about $2200 from ATK. He’s put about 2k miles on it so far and has had zero issues.
Now, you’d also need a replacement clutch and flywheel (they’re different for the LNF and LE5), a tune and an intake, but my feeling is that you’d wind up with a more stable result.
I love the turbo kit on my ‘06, but the LNF is a different beast.
On the note of turbo vs SC:
I enjoy driving an SC-equipped car a LOT more than turbos. It's as close to an NA torque curve as you're going to get in a forced-induction application. I've heard many times about the power that SCs take to run, and that's true. In the "Jay Leno's Garage" episode on the C7 ZR-1, the Chevy rep mentioned that the supercharger took something like 300HP to run at redline. (Of course, it generates way more than that, or else it'd be a waste of time.)
In a perfect world, we'd have a nice 48V electrical system capable of (easily) running some sort of electric turbo assist at low RPM to combat lag. Or a nice big V8.
