You are under a very misguided impression then. If you would like, there are plenty of English Torahs running around and I think you will find about 30 lines into it exactly how much "translational difference" there might be. It isn't even the same book.
The messiah in the Torah is the king that restores the Jewish kingom and brings upon the messianic age. You are going to have a hard time convincing any Jew that Jesus was a messiah, because all of the things that were supposed to happen, didn't. That of course is all explained in the New Testament saying why everything that was written in the Old Testament doesn't apply anymore, but again, why does anyone choose to believe one over the other? Where is the reason for that decision?
