I believe it can be a bit of a minefield with the different years and kw for injectors, maybe some who have done it can shed light.
I've recently changed my scv, gas filter, diesel filter and oil/filter, the oil pick up was clear, the sound now is amazing.
It's gone from a 2006 lc3 clattery old diesel to a very much quieter, smoother engine, even my mrs commented when I turned in the yard. It seems that maybe it wasnt looked after correctly by Toyota from a full book of stamps with the previous owner.
