Twin Turbos

Where can I find them? I saw them once online for a full twin turbo kit that put out 550hp at 6psi for only $5000, and I have completely lost the site. <br>

I need help. I have a clk 430 with a full body kit and rear spoiler and it looks faster then anything...only it's not! <br>

There is a Kleemann Supercharger kit which I'm getting that puts out 430HP. I have a bunch of info on it if you'd like, just email me.
