please educate me on 4 and 6 cyl turbo deisel patrol
hi there,im in the market for a 99 model GU turbo deisel.
iv looked at heaps and have my heart set on one,but someone asked me today whats the differents between the 4 cyl ones and the 6 cyl turbo deisel.
i had no answer apart from more turque from the 6....
what are the pros and cons of the both and what is the better and more reliable option.

if you stand still ill drive over you
is it the 2.8, 4.2 or 3L. dont nkow much about the RD28, but its a little six in my opinion.......i dont know what difference that makes, but the 4.2 is a proven engine. the 3L had lots of little problems on the early ones (99 is an early one) check if the probs have been sorted and it should be fine.
different hp and torque curve
4.2s don't have electrics
3Ls are all computerised drive by wire etc
4.2 is more reliable as its old skool tech
3Ls now are fairly reliable they've sorted out the bugs
4.2 lots of mods available fairly cheap
3L some mods available at expence
both all come down to how deep ur pocket is
4.2s are noisey
3L smooth and quiet
if it was me looking for the car i would take the 4.2 turbo ... and i dare say the majority of people here would as well ....
all comes down how much u wanna spend as well

The 4.2's come with a bigger and stronger gearbox than the other two.
You have the advantage of towing power with the 4.2 over the other two.
The 3 litre has electrics and a computer to run it.
The 4.2 motor and gearbox are proven.
the 3l and 2.8 are reconised as problems.

torque
I am not sure but I think the power and torque figures are taken at the rear wheel. So the gearbox and clutch apply more stress in the 3.0 ltr. The gearbox and clutch in the 4.2 ltr are much stronger and more robust so the gear has an easier life.

GU Patrol - 4" Lift- 285/75/16 Coopers STT's
Lets just say this, More Cylinders, more power.
The RD28T is a very gutless motor when it comes to towing and hills, but has more off the mark speed than the 4.2TD (this was what i found).
The ZD30 was also great off the mark, but towing and offroad, it lacks alot, but it much better than the RD28T in terms of power
the TD42T is fantastic, in fact i am very disapointed i got a TB42 engine.
TD42T run hard, tow well and go forever.

patrol.
well than that has made the choice so much easyer.
atleast now i can answer my own questions,and also when the wifey ask them to.
i think to be honest im going to go with the 3.0L turbo deisel.
the reason being is i wont ever be towing anything,and as far as 4x4ing goes the sand and some light bush is all i will be doing as im paying enough for this thing and dont wont to damage anything.
i come from a drag racing back ground where bigger is always better,so in this case yes the bigger 6 should be the way to go.
but as some people have said,the 3.0l has had the bugs ironed out and makes good power,my mate owns a 4x4 shop in noosa and i think sells d-tronics for them,couple of after market bolt ons and i think ill be happy.
iv now changed my mind on the truck that i want and found a truck last night that is a 2002 and is choc a bloc full of options and things and is bloody cheap with just under 100k klm.so im going for a test drive thismorning and may bring her home.
cheers scotty

if you stand still ill drive over you
For your driving requirements you have made a good choice.
I drive an 04 STR navara with a ZD30 and love it, and its very economical and tows our 20foot v8 ski boat without dramas. The old man liked it so much he recently swapped his 4.5petrol GU for a ZD30 GUIIII.
But he does have a GQ SWB TD42 for the tuff stuff.

The 3lt is a good choice for the basic blue moon holiday or trip up the beach or the soccer mum. Cheaper to purchase, cheaper to run.
For somone in a club or takes trips often offroad, tows often loves there offroading but cannot afford the TD4.2 then the 4.5 on LPG is a good alternative.
For me if I could not afford the TD4.2 then the 4.5 on LPG is my second choice.
I could get me a 4.5 160 000km leather sunroof electrics new tyres auto immaculate $15 000. And yes the Auto's are strong aswell.

the 3L uses a smaller box than the 4.2L as it doesn't have enough power to run a 4.2L box
The 2.8 runs the same box as the 2.8GQ and 3lt GQ (this box is also the same one found in 300zx Nissans).
But the ZD30 and TD42 us the same one (FSR50?? I think).
And yes there was a batch with a dodgy 5th gear (in both ZD30 and TD42). But these should all be fixed by now.
Oh and also the ZD30 has 4more KW and 20nm more. Its just that the TD42 will have more off boost than the ZD30.

THOUGHT FOR THE DAY....
I hope i'm not going to be considered as hijacking this thread by asking the following question but as we're talking different types of nissan engines...
... can someone please inform me of the difference between the TD42, a TD42T and a TD42Ti engines? I thought Nissan only ever made two types of 4.2 litre diesels; one a turbo and another a non turbo but i appear to be mistaken

the TD42Ti is the new intercooled motor with electronic controled injector punp, under the skin there all prity much the same.
I don't know why people still like the 3.0L my experiance is there still a handgrenade motor and the longer you keep them the more likely to have them blow up in your face. all the electronic stuff on them tend to play up on you if you do dirt road driving as our work one is.

Turps can you confirm this as this is very interesting to me.
LudaCris
i could next week. Should be away camping with my brother and he has a ZD30 with 5spd.
But I am still looking for where I read it.
Just messaged Roly who had a zd30 GU. And he confirmed the gearbox is the same.
THOUGHT FOR THE DAY....
is there anything different internally then between the TD42 and TD42T? I ask as i don't want to pay extra for a TD42T over a TD42 from a wreckers if i'm only going to get a different manifold for a turbo that i'll only take off and replace with an aftermarket tubo and manifold from someone like AXT.

Pre 93 Td42 engines are supposed to have heavier pistons which are suitable for high boost turbo applications. After that the pistons are lighter but I think are ok for turbo provided the pressure aint turned up mad. I`m not sure but I would think that TD42t would have the heavier pistons but then maybe not. Someone will know. I only know all this because of this fine forum

My understanding is that it is pre 95 TD42 are the same intetnals as the TD42T but the post 95 TD42 has lighter pistons and maybee some other internals. But it still handles turbos fine, but keep a handle on how much boost you run on a post95, the pre 95 to my understanding handle a fair bit befoure complaining
