Hey guys I have a 3.0L V6 1991 Pajero just wondering if there are any swaps i can do with gear ratios to improve offroad ability with larger tyres... I know the 3.5 can swap with the 2.8 diesel ratios can the 3.0L do the same???

Have a hunt around in the Tech database.
If you have a LWB, you probably have 4.675 diffs. The SWB
has 4.875 diffs, base model N/A diesels (from memory) have 5.29 diffs.
However, 5.29 diff ratios are hard to find, and not compatible with available lockers.
Later model (3.5 / 2.8) have similar ratios, but the rear diff is larger. Front diff may be the same if you have a manual gearbox. If you have the auto, your front diff is smaller.

what ratios are you running atm? check ur build plate in the engine bay for ur transaxle code and the numbers that read something along the lines of 4.625 etc is ur diff ratio, then cross refernece with the data available in the mitsi bible in the mitsubishi section on outers

Ahh so that's where it tells me. (trans axle code)
You learn something every day .. (I seem to forget more than I learn, but that's another story)
