If it’s on spool up its most probably bearings in the turbo.
If it sounds like an old WW2 air raid siren a squalling ringing metal sound I would say bearings
If it sounds like a hissing nose then leaking intercooler you should also note a large drop in power or lack of when taking off etc.
I would be checking for a number of things like blue smoke from the exhaust, check air and vacuum lines, check for oil in the intercooler, how many kms has the 4wd done ?
Patrols are known for oil in the intake just make sure it’s not shit loads

Rayman, does it sound like a siren or a sweet whistle? It's not just the turbo winding up under load when you accelerate? Does it make the same sound all the time, ie at idle, under load, cruising?
cheers

yes it makes the same sound under all three mentioned just varies a little with revs
Ok, well in that case I can't offer anything beyond what roofy & bushytas have offered above, sorry.
cheers,
