Default Standard plug vs. Turbo plug

Are the engines the same except for the head button?

well since your questions is so vauge... if you get a turbo plug you need a different head button. so if you bought an engine and it said "turbo plug" or something then yes that would be one difference but the engine could be better built or something to make it a "turbo version" of the original

like the OS 18 TM and the OS 18 TZ, the TZ is supposedly faster and supposed to be turbo..

The standard plug uses a copper washer to seal the combustion chamber like a ring on a full size spark plug. There is no taper to the plug and it leaves a big flat spot in the dome of the combustion chamber.

A turbo plug doesn't use a washer and relies on a taper at the bottom of the plug which is supposed to match a taper built into the head button. This is what makes a seal for the combustion chamber and is considered a better seal then the copper washer. Because the plug is tapered the flat part of the plug that is at the top of the combustion chamber is smaller and allows for a more domed combustion chamber.

The tigher seal and better shape of the combustion chamber will improve the engines performance and that is why most high performance engines today use turbo plugs instead of standard.

Sorry...let me re-state my question.
I have a ton of turbo plugs and an engine that has a "standard" head button.
Can I just put a turbo plug head button on it and run it without any other mods?
