hi from kiwiland
my not so baby godzilla is running a rb30det with a gtr box and it probably more fun than a stock gtr .
if you want to put a 25det in you can use an adapter plate between the sump and block with the rwd blocks.awd blocks are wider at the bottom to accommodate the gts4/gtr sumps.
the gts4 boxs r ok but the gtr boxes r heavier ?stronger with a very tall gears(im getting about 65km out of 1st )
the best post is the "r33 rb30 conversion" which covers most the 4wd mods needed for the rb30det which will be the same for the rb25det but if you're gonna put an rb25 in you might as well put an rb30 in as it gives you a bigger bang for your bucks.
p.s im pretty sure R.I.P.S uses an r33 gtr box in his 10 gts4 rb30det
