If you have basic mecinacial skills then go for it.
Get a turbo/manafold/dump pipe from a Td27, usually found on a terrano.
The manafoild bolts directly to your QD
so you will need to :
Sort out oil feed and return - feed should be tap-able from oil filter housing or your oil pressure sensor, return will need to be custom.
Sort out water lines - tap into your heater lines, easy done.
adapt the dump pipe to your current exhaust, easy if you can weld
Sort out your intake pipe and pressure pipe - easy with some silicone joiners and spare pipe.
then you need to adjust your diesel fuel injection, as qd not factory turbo it does not have the boost compinsator.
or you could import a Qd32 factory turbo motor from Japan and swap it out.
