I had similar lack of info when I asked about later gearboxes for a 1991 2.5td.
Why would you want to swap? The 2.5 is probably as fast as the non turbo 2.8
If you get any info about whether the 2.8 bolts on to the 2.5 box or whether a later box is stronger & goes onto the 2.5 I would appreciate hearing about it.
Triton/Pajero are a good jigger except for the gearbox & I would like to know if this has changed.

Yes it will fit, it is the same block, but the gear ratios will disapiont. The 2.8 runs a taller diff, it would be terific of road but a bit slower on the highway. Eric.

Eric, I thought that the taller diff would be better on highway as the diff in the 2.5td makes a few revs. The taller diff off road would be at a disadvantage due to faster 1st gear if it really is taller.
My 2.5td gets up to 135kmph or better with an accurate speedo, depending on whether I have wide or standard tyres. They also affect fuel consumption.
I am sure my feul pump also was not set properly from new as the exhaust has always been very dirty when you plant the right foot at low rpm.
I got adventurous & took the top off the injector pump & spotted the toothed spring loaded cog then turned it clockwise quite a bit until I got the right setting with lively performance & less smoke. Have yet to test km/litre but must be better.
The mixture can be rest more easily, so I found, by removing the brass plug on the end of the pump & inserting a screwdriver till it touches the toothed wheel & rotating it left or right as required. Too lean & the mootor is less reluctant to power up to higher rpm.
I digress here but thought it may interest some.

Rex, 3000rpm gives 105kmph & 4050 approx at 135kmh.
Only do the latter when I have made some change or testing it.
Motor seems quite happy at most rpm & cruises above the 100 limit easily if required but I usually keep it at or below 100.
Done 220,000 & its very smooth when warm .
Dont know how long it would last at coinsistent 4000rpm but I heard of another 2.5 up here with 500,000 on the clock & poorly treated too.
