Anyone know the name of this karate movie from the 80's?

(And no, it's not "The Karate Kid") I thought it was called, "No retreat, no surrender", because that line is said several times in the movie, but it's not. It came out in the 80's and it's about this kid who moves to a new city and he is trying to self-train in karate. His idol is, of course, Bruce Lee. Then Bruce Lee's ghost comes to life and trains this kid how to fight and the kid ends up fighting these neighborhood bullies and at the "big fight" between them, the kid's friend yells to him, "No retreat, No surrender!" and the kid gets inspired and wins. I remember watching this movie when I was a kid, around 1985 I think, and I loved it. But I don't know what it's called. I thought it was called no retreat no surrender but I have looked everywhere under that title and none of the movies I find are the same one I saw back in '85. Anyone got any clues?
