I'm basically in the market for a new fourby, and I'm pretty sure it's gonna be a GQ.
I've never owned a diesel before, or a Nissan for that matter.
My main goal is efficiency and range, but I don't want gutless either.
With that goal in mind, would the 2.8L Turbo Diesel be better than the 4.2L Diesel??
for what you want mate the rd28t will be fine. with some small mods you can get more power out of it, without blowing the fuel budget out the window. td42 can produce alot more power with mods but fuel would be then the issue
good luck
MQ Dual Cab RB30 INJ well on its way....

There are a million threads on this debate both on here and on the patrol forum. Do a search a have a read through them all and make your own mind up as to whether the vehicle will suit your purpose.
2.8 = entry level and you will be content, (no offence to current 2.8 owners), after having owned a 2.8 for 3-6 months...you will probably wish you went 4.2 at the time.
Yeah TBH, I would be driving to work in it every day, Hurstville to North Sydney, and that would be it's primary use. I mainly want a bigger range vehicle so I can tour, cape york, outback etc, with a BUNCH of people (not just a +1). Things the soft top Sierra simply cannot do..
Basically what I'm trying to ascertain is what is more efficient. Looks like that'l be the 2.8 turbo.

Sounds like you have it sussed Will you be towing or looking at bigger tyres at all?

I'll definitely be adding larger tyres, probably not towing. The amount of extra space will me enough already , probably just remove the rear back seats, that'l be ample.
hey buddy ive had a 2.8 for about 2 months now and just got a 3" exhaust from turbo back and wound up the boost a little and have just put 285/75s on it and it still goes fairly well. but ive taken out rear seats as in the 6/7th and i never load up or tow but i think its a great truck with a few small mods. oh and yeah pretty good on fuel ay
but the 4.2s are also good cuz my brother has 1 i reckon that you test drive both but remember the 2.8 will need mods if a standard 1 cuz they are poo without em, hope ive helped.
umm got a good price from my brothers mate at toys exhausts in kippa ring (redcliffe) and got quotes from beaudesert exhausts just for a 2 and 3/4 system without dump pipe and install myself and got full exhaust, dump pipe all tucked up nice, 1 straight through hot dog muffler installed and a borrow car for the day for a bit over half the other quotes for smaller uninstalled exhaust minus the dump pipe. So it pays to ring around it is the best mod you could do to a standard rd28t i reckon, i was stoked when i got it back, very good work buy toys. I wouldnt go any smaller than 3", a few exhaust shops have told me the same, sounds very good too, and sounds quiet and normal when cruzing.

I've read you get pretty good results with a zorst on the rd28t's. I rang beaudesert today and they quoted me about $1,000 delivered to Melbourne for a mild steel system from turbo back. Beaudesert said they put a 2 3/4" on the 2.8s and its pretty easy to fit as its just a bolt on replacement.
How much did yours end up costing if you dont mind me asking?
what economy do the 2.8s give?
i really dont think they would be much better than 11.5L/100 which is easy from a TD42, even on 35s 12L/100km is do able.
i know the 4.2 is all i would be looking at
97 GQ patrol coilcab. TD42, safari turbo kit with fiddled turbo, D-GAS kit. dyno results to come...
4inch lift, king springs, efs and procomp shocks
315/70R16 cooper ST's
found fuel economy...

exactly.
doesn't mater what engine it has (to a degree) it's still trying to push that same GQ wagon along the road. same reason 4cyl camrys use a heap of feul.

Yeah I hear the 2.8TD use roughly 9L/100km. Citation needed, but thats what I've heard.

9L/100 is a bit light on..... I get anywhere between 11 and 17 depending on conditions roof rack on or off etc. Generally 12 - 13 on the highway running 33s though.
If you sat on 80 km/h you might be able to do 9s but life is too short for that.

How come??[/quote]
Just thought that you'll probably fancy 33's one day and I don't know how the 2.8's with their gearing handle them? - A few people on here will give you some idea!
My GU with 33's is better than my old 4.2 GQ with 33's on road, but doesn't come close off road if you need low down grunt.
I'm not sure if the electronic pump on the GU is better or worse for extracting more power easily though.
It comes down to whats available too, at what price. Was it a lwb you were looking at? (never seen a lwb 2.8 GQ)
Given the choice, at the right price, the 4.2 would always be my first choice, but the lwb GU with 2.8's seem quite cheap there, and a good start for a motor swap later on if needed (if you get it at the right price of course)
9L to the hundred is pushing it!
new common rail diesels in patrols dont do that so i doubt the old 2.8 would.
even the ford rangers are having to be conservative to get down to that
