Change 90 amp alternator to a 150 amp.

I need to change out my alternator on my 2004 Freightliner (Dodge) Sprinter 2500, is there any problem with the wiring to change from a 90 amp. to a 150 amp. alternator.

I see no problem changing over as, the only changes to the alternator are internally the 90 amp uses different output diodes than the 150 no adaptor should be needed

The battery post (B+ on alternator) wire must be up graded to at least 2 Gage's larger.
