lol... you can Never clock a TD05-T25... for the sole reason that they dont exist.

you can clock a T25 OR a TD05... there is a pin where there exhaust housing meets the center section... chances are, that will break anyways when you try to separate the exhaust housing. for the cold side, that one is slightly harder with the C-clip and all.

you jus thave to worry about how you want to mount the Wastegate actuator... or eliminate it and run with an external. then you are free to clock any way you see fit.
