wanting a turbo for my 2JZGE

I've read in other forums and what not that I can throw a supra turbo on my 00 gs300 and it would work, minus the fact that I would have to change out my tranny after a while. I'm not looking for high HP nothing really over 400hp.
I want a little extra boost to my ride. So is there anyone out there that can help me locate a turbo and let me know what else I would need to make my NA to NA-T. please help me out. thanks Tony
