No, nobody here knows anything. Here's a list of what we don't know: we don't know what year Tiburon you are talking about. We also don't know what engine you are talking about.

How about instead of complaining about this forum and creating duplicate threads, start providing us with a little information about your Tiburon. We can't read minds here.
