I have a 1hz 4.2 litre diesel in my troopy.There are 250,000 km on the clock,the motor does not use oil or blow smoke and seems to be sound with no unusual rattles or groans.Turbotech in W.A can fit a Garret watercooled turbo with a 2.5inch exhaust for $3,500.
Do I need to make any modifcations to handle the turbo?

Hi Terry,
Had the blokes there fit a turbo to my 4.2 GQ with 235000 on the clock, same deal, same cost, also got a
snorkel. They did good job and the old girl goes like a shower of faeces now. No modifications needed. Ask Bill from turbotech if you are unsure bout anything. I'm off there tomorrow for a tighten up after the settle in of
mine.
BTW I think I get better economy now, certainly when towing. Engine temp rises up to 3/4 of hot on a warm day working it hard, but I think that is helpful in fuel combustion anyway. Certainly doesnt overheat, which I was concerned it would.
good luck
Dave

Keep an eye on the radiator fins.... if you go off road, the dust gets in them and turns to mud in rain/puddles/creeks/rivers etc..... and slows down the heat transfer dramatically. I pull our radiator out every 3 or 4 months and thoroughly clean it and give it a light coat of paint and temp propblems are eased!

The difference between the GQ motor though is that nissan use the same crank and bearings etc when they bring out a factory turbo. The nissan motor may be a dinosaur as far as tech is concerned but its as tough as nuts. The 1hz is renowned for problems with the main engine bearings and for not being able to handle a turbo. I would make sure you get a warranty and look right into it, personally i wouldn't be doing it.

250K's???? The motor's just run in! ;-)
Seriously though, we have just had our GQ turboed at 253K's.... and a mate has rebuilt his 80 series and added a turbo as
well. I am very happy with ours, it has made such a difference!
Used a TurboGlide system from Russellvale in NSW, including the 21/2" exhaust and had injectors done as
well and a big service to the truck. Goes like a rocket!
I can't see the 80 being any different, but
check with a couple of mechanics as
well to settle your mind.

I did my 80 at 273 00 km.
Get it compression tested.
Have the injectors done and most of all FIT AN EGT.
If these are not set up right they will crack pistons but when done right you will have no problems.
You can get these things cracking but they don't last for long. If the fuel is set wrong they can over heat as
well. The EGT will tell you everything.
No higher boost than 8 psi and no higher EGT than 500 deg at full throttle for 2 minutes. Thats if the probe is directly after the turbine.
Don't be too worried so long as you have it tuned right.
