GU - 3.0 Vs 4.2 Diesel

Hey Guys,
First of many questions, please bare with me but I need to know!

Looking at a PDF on the nissan web site the evoloution of the nissan patrol engines. I noticed the out put specs of the 4.2 & 3.0 are not that different.

TD42T 4.2 litre, water cooled,diesel engine, turbo,
114 kw @ 3600 R/min 330 Nm @ 2000 R/min

TD42Ti 4.2 litre, water cooled, turbo diesel, intercooled,
114 kw @ 3600 R/min 360 Nm @ 2000 R/min

ZD30DDTi 3.0 litre, water cooled, turbo diesel, intercooled,
118kw @ 3600 R/Min 354 Nm @ 2000 R/Min

ZD30DDTi 3.0 litre, water cooled, turbo diesel, intercooled, common rail,
118kw @ 3600R/Min 354 Nm @ 2000 R/Min .


I guess what im wondering is how does the ZD30DDTi drive against the TD42T, forget what it says on paper what is the real world experience? Fuel constumption, Overtaking, Towing patricularly up hills , down hill decent (engine braking) etc. The other thing drivability as a daily driver given I have to pass throught he city every day.

Love to hear your thoughts and experiences.

Oh, and if any one can tell me which year/series each engine became available that would be a bonus too.

Not sure about the years they cam into play etc mate, but my last GU had the turbo diesel 3 litre and it was outstanding. A great motor, plenty of low down grunt and fairly economical considering the size of the rig.

This should be a topic you'll get plenty of response to mate, so hang tight and others will weigh into the discussion to assist also no doubt.

not from experience but most people say that the 4.2 ti is the go. I have a zd30 in mine and as long as you're on boost it goes very well perky tourquey and fuel is about 13 L per 100km combined driving early Di models 99 to 02 models are the grenade engines so get a 03 to 07 model I think 07 is common rail engine appeared and replaced the Di.
The common rail tends to be thirsty on the juice apparently but doesn't seem to have many problems neither did the later Di models.
The 4.2 is everyones fav. not sure on fuel consumption but does what the 3.0 does but in a higher gear and has a good reputation as the early zd30 motors are suspect .
It's a personal choice and a financial choice as 4.2's carry a premium I went the 03 Zd30 and doing some mods to increase reliability and I love it goes better than holden suzi and toyota off road and you can't go wrong with a nissan unless you get a 99 to 02 zd30 motor!

The 4.2' s can be modded to produce a lot more power than the 3.0 L. For this reason they are prefered for more extreme offroad/ comp situations and also to heavy heavy towing. They also hold their value longer and will not depreciate as quickly as a 3.0L, and thayey sound awesomly tough with the right exhaust and mods.
The 3.0 Di up to series II 2002 where considered to be a bit of a hand grenade but few would be left with problems these days. To be on the safe side series III's are prefered over the series II for that reason, as Nissan had sorted the problems by then, But some mods are still prefered to be performed just to be on the safe side, like blocking the EGR and regular cleaning of the MAF sensor [think of these things as preventive matainence]
The shape of the Patrol changed very late in 2004 now a series IV with flattened flares made as part of the body, as opposed to the more tacked on plastic look type on the series III. The dash also changed but the 3.0Di remained till it was changed over to CRD in 2007.

If your're into the tough stuff and very heavy towing, and got the $'s to spend to make a super toughttruck that will annoy the neibours with black smoke and turbo whistle, go the 4.2, but it'll cot more to buy than a 3.0L.

If the above is not too much of a concern then go the 3.0L and if you want more power, just chip it. The CRD's,.. well some have had drama's with bad fuel economy and others have not. The pick of the bunch in the 3.0L feild would then be the 3.0 Di series IV [2005 - 2006 ] with the revised body and dash just before the CRD of 2007.

So there goes... I 've done me researh, now I just got to get my hands on a Patrol. Anyone want to give me one... ? :bowdown: I'd like a 05-06 series IV 3.0 ST-L with a manual box and grey leather.... Thanks.:toot:

I'll even give you my 1993 DC Hilux with all the ARB fruit, [Air lockers ect] :049:

Luxo has pretty much nail it in his response....


Also, I think u may open a can of worms here. This has been done to death and you will get the "4.2 all the way" fanboys start ranting about how every 3ltr blows.... "my mates brothers sisters boyfriend had his 3ltr go bang" Blah blah blah.

As long as you stay away from the 2000 - S2 2002 models, you should be fine.

Also, it went a little like this..... Series 1 GU 2.8ltr (08-99) -> Series 2 ZD30 (2000 - late 2002) -> Series 3 ZD30 (late 2002 - 2004 ????)... Thats all I know. Common rail was introduced in 2007 as mentioned above...

Cheers

I'd love to help, but no I don't lol. I spent 10 months of visiting patrols for sale to finally settle for the one I have now... Was frustrating!

Hey thank you guys for the input, seems like a GU IV with low Ks seems to be my choice, strangely Ive seem a couple of GU III with 60Ks on the clock advertised which did catch my eye just seem a little pricey.
As for towing right now in the forseeble future my outback sturt camper trailer is whats going to be hanging out the back 700kg dry and about 900kg loaded shouldnt give any of these trolls too much grief.

Like you Luxo, the finance minister has taken to the idea of leather inside!

TD42 is iron fellow with timing-gear on pinions, remembers Okinawa.
ZD30 is the aluminium fruit of modern marketing and service-owners demands.

Depends what You need: off-road or on-road car????

Hi Starck,
The Patrol must be multifunctional
1. My daily driver 100 klm round trip good percentage of it in built up traffic.
2. Family tourer with camper trailer and travel anywhere in .
3. Offroader for easy medium trails (have a 5L Rangie for the hard stuff)
