Just bought this novarossi engine
 

Here's a link to a novarossi engine I just bought.

Is it a good buy? To me, it looks like another Mugen MT12 engine, but the guy says its a Novarossi NSL-3 engine. On the sides of the engine, it says Nova on one side, and M12 on the other, which leads me to believe its a Mugen MT12. Its hard to tell because he changed the head to a cooling head. But the engine does use a turbo plug, which I dont think the MT12 uses.

Anyhow, let me know what you guys think.
