    time to buy a VXR unit. mine squeels a bit but still holds 22 (overboost)-16 psi full throttle. the blue smoke isnt good TBH. as the turbo would be the cheaper option to change i'd go for that, i doubt (and hope) its not a ring.

    the only things i can think of are the plugs in the center of the turbo (blanks) u need to swap them (cant remember if there is one or two) with the old unit... thats it.
