Turbo inserts?

Is there any sites out there that make turbochargers that you can put into your engines? I'm looking for some that would fit into the Tamiya 350Z.

Scale Speed Works makes turbos but the Z doesnt have an engine.

D'oh! In that case I'll be needing a 350Z engine as well. Know where to find one?

You cant just buy one. You could scratch build one.

Well I better scratch that idea. Now I need to find a different car. . .
