there's the GM supercharger kit that was just released for the ecotec engine but that won't get you the blow off valve noise because there's no blow off valve. you could get the RSM kit like you said, but its pricey and i've heard of a lot of people having problems with it. then there's the Hahn Racecraft turbo kit for the ecotec, but the intercooler piping was made for a manual tranny, so you'd have to fabricate your own pipes.
then there's the option of building your own turbo kit piece by piece. in my opinion, this is the most cost effective way to boost your engine because you get to select what parts you want to have and where you buy them, instead of having a premade kit with certain parts you might not neccessarily want.
