Hi all
Just wondering on what your thoughts are on the navara engines?
Which one is the better engine out of the two?
I am a bit sceptical about purchasing the 3litre varient as they are almost the same engine as in the patrols. They are both ZD30's but the power outputs are different.
Any information will be appreciated.
Cheers
Matt

We have a mixed fleet of Luxs, tritons and Navaras at work. My advice is test drive either of the others. If shopping on price the Trition leaves any Navara for dead and have been trouble free, which I can not say for the Navaras. Dmax is well worth a look to as have heard lotsc of good reports.

Thanks madfisher
I will not be purchasing a new car, i was interested in the d22's. Im not a fan of the tritons, just because i can see myself becoming sick of the looks.
I like the d22's and the pre '05 hilux's. I do like the dmax and ranger/bt50 but there is not many for sale in south australia that are of affordable price.

To be honest we do get a better run out of d22s then the 40s. Get a man though as the autos are slugs. Brother has a zd30 navara and its has cost him heaps while his old 95 lux he sold to buy the navara is still plodding along with no major expenses. My pick would be a pre 05 Lux, much heavier metal in the bodies then the current ones plus better clearance, and cheaper to repair.

I'd disagree with Madfisher on one key point.....and that is that the autos are slugs....quite the contrary. My D40 auto has buckloads of power and torque and is far better suited to towing than a manual. IMHO if you are towing anything heavier than your garden 6x4 box trailer then go auto regardless of the make/model of vehicle you get....the current crop of manuals mated to the dual mass flywheels are lightweights and cannot handle the load. Read any of the forums....Navaria asia, Newhilux, triton etc etc and all seem to be having problems with early and frequent clutch failures.

Mate we unfortunalty have six of these buckets of( ) . I drive d40s d22 s Tritons Hiluxs sv6s xr6s, almost on a daily basis and all of our autos d40 are all noise and no go. Maybe we just happened to get six duds, but I doubt it. I am sure if you drove nothing else you would think their fine. If anyone doubts what I say I am prepared to take them for a spin in a d40 then a Triton to see the diff. I do not doubt what you say about clutchs but we have no issues ,but are sold off by 100000ks. Patrol do your self a favour and drive some of the others. The other autos all go well. Even the d22 man leaves the d40 auto for dead. We also have a d40 at the dealer every week to sort out a problem. Most minor, but still off the road.

I guess mine must've been a Wednesday manufacture then :-) Lots of guts, even when towing my 1.5 tonne off road camper. It's not as if I just run mine on the formed roads either it has done the trek from Steep Point in WA to Cape Byron in NSW .....through the middle - lots of corrugations and sand and certainly didn't want for power. I've done myself the favour and driven the lot....and none are more powerful IMHO than the D40. I laboured over making the decision to buy for several months and it came down to the D40 or the Hilux....and unfortunately the 'lux lost out because of its very ordinary towing capacity. I'm happy thus far with my decision...no problems whatsoever and it now has 65000km on the clock and about half of that has been clocked up towing.

The 2.5L motor is not a ZD30 at all.

Sorry - I see your comparing patrol to the 3.0 navara donk.

Brother in law has had a D40 with the 2.5 for about 4 years. It goes well when it's not in the shop (regularly) for having DPF issues or spitting the rear diff.

Diesel particular filter. It in the exhaust system to cut polution. Main thing is to run the correct low ash oil or you will be up for $5000.

There is a way around the shortcomings of the DPF, and that is by fitting a DPF DELETE PIPE. Not entirely legal mind you as is circumvents part of the Euro 5 emission standards that have now (or about to be) been adopted in Aus.

We had the 3.0L DID D22's in our fleet and then went to the 2.5L CRD D22's. Worst move we ever did. Would never go back to a CRD D22 again.

Our cars are used at the mines to move communications trailers and access heavy equipment. Slow going driving with a 200kg trailer on the back over semi rough ground meant that the 2.5's just couldn't get going even in low range. Burnt out clutches and everything. We rechipped them but the guys were still unhappy so ended up going to Ford Rangers. That was the best move we made.

The 3.0L DID engine was a hell of a lot better and we still have those cars today.

Regards
David

Mechanically it was fine but it is severly underpowered, especially at low speeds and when towing. It also has terrible throttle response and lag so it was impossible to get movimg quickly.

I'd suggest that you it might be worthwhile asking the people that actually own Navaras and who have had them for some time. A good place to start in the Navara Forum

The people who own them for and look after them.....I too worked for miners in the past and a large electricity company as well...and the company cars were flogged by everyone who drove them. Not suggesting that these vehicles are trouble free....like every other vehicle on the market they have their share of problems. But from my personal experience I find that every vehicle I've owned has served me well and I put that down to care and good maintenance - IMHO while you might get the latter in large corporations/miners you won't get the former from the plethora of drivers that get behind the wheels.

Good point Patrol, but that does not explain why the only trouble we have with luxes is dirty fuel. Can not remember when we had one in for warranty work. Ravs are a diff story.

Matt,

I have an '04 D22 Navara (zd30). Bought it in '06 with 92k on the clock, now have 170k. I had a turbo issue early on (fixed under warranty), but have had no problems since that I have not caused. The ZD30 in the Navara seems to be a much better variant than the early Patrol, as few failures are reported. It's been a great vehicle for my needs, light off road and towing.

It has great economy, with reasonable power output, albeit the turbo lag down low towing requires some clutch slippage to get moving when towing on hills(nowhere near as bad as the current YD25 or Mazda/Ford vehicles though). Against it: rear legroom is pitiful to be kind! The is paper thin, but that is what most likely gives it the zip power to weight! Basically Nissan have not changed much with the vehicle since the 1987 D21, drivetrainwise so it's pretty safe there!

The YD25 is a common rail set-up and seems to be quite expensive when failures occur due to poor quality fuel or the like. It's a bit down in power to the ZD30 when driving, but looks better on paper. I have driven a few, and to be honest would not upgrade to the later model from my experience.

cheers.

A big problem with a large number of 4X4's these days is that the manuals have dual mass flywheels that are quickly gaining a reputaion for unreliability towing heavy trailers. My persoanl preference is to the Auto's.
The 2.5 Lt Navarra has both more power and torque than the 3.0.

Not in the d22? 110kw for the zd30 versus 96kw for the 2.5. (from memory)

They've certainly been playing around with the tune in that 2.5 engine....in my 2008 D40 it is 128kw, in the 2010+ it is 140kw and in the D22 it is 96kw I believe. Only takes a Chipit chip to bring all the lower readings up to 140kw though.
