Question; How much do the tray back XR6T’s ute’s weigh?

Hi all, Sorry for the newbie XR6T questions. What is the recommended max rpm these engines like to rev to before they start to run into trouble? It already has a good set of valve springs, custom exhaust manifold, larger turbo, external wastgate, flash tuner, injectors, fuel pump, custom intercooler, 3.5” dump pipe and twin 3” exhausts.. Cheers, The Juggernaut.
