Turbo as in conical glowplug? Yes.
Since conical plugs are legal I don't think you will find many top engines with a standard plug.
The NSR 12S3 is a 3-port so should be legal wherever you race. I have this engine in my 710 and it's simply awesome... Currently running it with the older RD Logics, but my TurboII is on it's way! If it's better than the old one (which it should be) you can't go wrong with it.
