supercharger- no lag, always boostin (lower MPGS), better throttle response, no special exhaust/ wastegate needed, draws power you would normally have in your engine because it is belt driven.

Turbocharger- Stages ( Bigger Turbo), Better MPGS with same or more power as a supercharger, need more upgrades to your engine to start off unless you are running low boost, even though you have to get bigger injectors to push more power with both the supercharger and turbo.

I would say go with the turbo, easier to change HP range without having to change pulleys especially if you have an electronic boost controller.

Neither is way better than the other. Biggest difference now is:
No more supercharged versions being made -- unless you could find a new '07 that has never been sold you won't have a full warranty. Since the Turbocharged version can be bought new you'd have a full warranty.

turbo charged. these smaller engines seem to respond better to turbos and alot better to upgrades then a supercharger.

i work at slowboy racing inc. which does 4 cylinder performance engines and we get some stock cars in (evo's, sti's etc...) that with just a few bolt ons and a tune push high 300hp/low 400hp with no internal work

There is a reason they swapped out the supercharger for the turbo.. Nuff said
It wasn't about performance, it was because they said the supercharged version couldn't meet the new Federal emissions requirements.

Where the supercharged version really "shines" is in appearance.....nothing like opening the hood and having a supercharger staring you in the face. The Turbocharged version just has bland tubing running over the engine.

Turbo... we only have four cylinders. A 4 cylinder reacts to turbo much better and the power is almost instantly there. Granted it takes a few thousand rpms to really kick. A supercharger takes power to create even more power. So the power thats not really there on a 4 cylinder to begin with gets taken away by a supercharger to create more power. With a small enough turbo and other mods to go with it, boost lag very well could be minimal. So i must agree with the turbo route. And yes both of them have their advantages and disadvantages just like everything else such as a charge throughout all RPM's vs a spool of only certain RPM's, larger turbos, larger pulley's and injectors so on and so forth but it is your car so you call the shots. Just make sure you definitally do your research. And by the way ZZP has great stage kits for the Supercharged Balts as well. Supposobvly better than GM themselves.
