What's up ? Dust-Devil, you having a bad day ??
I think Jim M1 was just telling us he bought a 2.8 diesel nissan, and as we all know they are slow and sluggish, And he has done some little Mods that have made a marked improvement on the perfomance,

I think he has the right to pass on that info without, getting any sarcastic remarks, Hope your day improves,? Rgs dazren

Well there you go Dazren, even you should be able to deduce what the 'and????'

He wanted to know about Diff lockers and if you weren't so occupied with being the forum Nazi you might like to tell him all about them

Dude.

Sarcasm about what may I ask,and while your explaining that, how about elucidating your theory on my knowledge of diff lockers.

Jim M1 himself is the first to mention diff lockers in this thread and his requirement for info on them. I was just indicating that requirement to you.

Am I missing something?
I can't see any reference to diff locks in the original post!

HI Jim,
Stick with it and don't worry about any criticism, they know not of what they speak.
The 28Td is as magic truck I had one and it took us and the camper all over Australia.
You have done some mods. I'm not sure where you are from but there is a mob at Sandgate, Qld who will put a chip in it for you which gives the same effect as a 3" turbo exhaust.
There is nothing wrong with the 2.8 Nissan turbo Diesel.
Kev

Hi there Jim,

Firstly, don't pay any attention to the sarcastic comments. It seems an inherent feature of this forum.

Look, the GQ's are a great vehicle. Regarding the drive train, I haven't heard of any issues with these models. However if you start running large tyres (35's or something) then you can *probably* expect to start breaking things (CV's in particular). ARB air lockers are a great investment, being stronger than the stock diffs. If you're just running standard tyres (or a BIT bigger) and you go easy on the old girl, the truck will give you years of service.

Cheers,

Tim.

Good to see the 'old skool' hot rod tricks work on the 2.8.
Leave the big tyres to the P-platers, taller tyres will destroy its around-town and low-speed off-road performance, and its fuel economy

Jim

Jump onto the Patrol Forum
Lots of advice there.

Plenty of them around,
Plenty of tricks you can do to get them up and running.

Just remember they can run with the best of them, if you go set them up the right way..

As far as Hard Core 4X4 Driving goes, don't wind them up too much, as the drive train (I have been told) lighter than their 4.2 lt, or 3 lt, counterpart.

Cheers
Bucky

I have a 96GQ 2.8 as well.
Goes great.
Only problem they had was that around 250 000 k's they can wreck their heads. I had mine rebuilt when mine happened.

As for gearboxes etc, I was talking to the Nissan mechanics here recently. Rarely did they have trouble with the gear boxes on GQ's, but apparently they always had one on the self for the GU's as that was a regular job.

A snorkel works well as well, but, you can hear a lot of induction noise with one. Apparently also common.

Hi ur not wrong about the induction noise, it sounds like its going to suck the world through the snorkel. I have a question? any body know how much boost the 2.8 GQ can take befor everything falls out? It has a after market intercooler fitted.

+1 have a GQ 2.8. everyone hates them but I like mine. Economy is good and its a 4wd not a race car so I expect to be slow. Jim, if your in Sydney would be good to get a bit more info on what you have done and where you got it done.
Thanks
Jase

Hi jase. yes I am in Sydney. I'm a mechanic I did all the little mods myself. Yes thay are a bit sluggish but a little bit of boost makes a big differents. It just has to be done right, diesels are very touchy it is all about the Exshust temps. Get it right & you will get good fuel economy when cruising and power when u need it. My GQ has done 462000km when I got it.. So I pulled the sump off check the bearings thay look good clean the oil pick up it had slug build up i also removed the turbo oil feed line put air through not happy so I changed it with a braided hoes just for peace of mind so far happy as.

Thanks SDG. I will, I'm willing to brake one to find out its limits. I don't want to but when you want more and more power something has to give. I would like it to hold about 12-16 pounds of boost and be reliable. Slowly I will found out.
