They wouldn't let me use a Type 40!  The Prince, the sanctimonious, pretentious Time Lord I had in mind wouldn't have even used his.

Though... Technically, according to the "science" there's no difference between a Type 40 and the Type 90.  The Type 40 can materialize via the Tree of Life everything it needs to become a type 90.  If it needs more power a TARDIS can just materialize around another star and add it's mass to it's own Eye of Harmony.

Nobody, not the fans, nor the writers, seem to realize how broken TARDIS are.
