1zk-te vs 1kd-fte

[Guest Close Guest]

Gday Lawrence,
What are you basing that low cetane level theory on? I thought that Australian diesel had been sorted out years ago, ie prior to Veedub & the rest of the Euros bringing out their own common rail diesels..? Anyways, our issues seem to be more about particles than burn rate.

If I'm wrong, you'll catch me up by the side of the road. If I'm right, you'd better have your snork on backwards.

I bought one of the runout '06 models (GXL TD Auto) new for $49,000. If I wanted to wait for the new D4D engine it would have cost nearly $10,000 more. As I plan to keep it till the wheels fall off, I wanted a simpler designed engine without the high pressure injection or a variable vane turbo. I'm still not convinced a variable vane turbo will last as long as a conventional one. I have no issues with performance as I had a 80 series intercooled 4.2 Turbo Diesel that performed similarly using more fuel. If I want to go somewhere fast, I book a flight. There is nothing wrong with the D4D, I'm just funny about new technology.

Haven't been online for quite a while, but have spent hours reading about D4D problems. I am glad now that I decided to go with the 'old' 1kz slug, I prefer reliability over performance.

Hi Lawrance,
Toyota's manual recommends diesel fuel of not lower than cetane number 50. As far as I am aware, all major oil companies in Australia comply.
What problems with cetane number/index are you referring to?
Cheers

I like the old 1kz technology, it works, has none of the d4d rattles and injector problems and it get there eventually. I wish everyone with the d4d motor the best, I'll be in the left hand lane, chugging along, like Mark, I feel reassured by the reliability of the 1kz. Just before christmas last year I was in the big desert national park (vic), it was 46 deg, driving in some pretty soft sand, air con blasting - wife happy and kids quiet, beer cold in the engel in the back - the prado never missed a beat. Of course, a lot of the reassurance comes from diligently maintaining your car and buying a toyota in the first place.

Look, at the end of the day, we all buy Toyotas for reliability, not Performance. That's what Toyotas reputation is built on. I Hope they pull their finger out and come to the party with fixing any problems their loyal customers have. Todays technology is just getting too much bull$hit when it comes to the 'ol 4x4. I for one dont need all the crap that is on a new 200 series cruiser.... the clowns that need all that technology never take the bloody things offroad anyway.

Well, I bought a D4D, so now I've got both. Solves the problem I suppose.

Re: 1zk-te vs 1kd-fte

This is my first Prado, the D4D, so I cannot compare, but doing 110km in 6th gear manual, dropping down to 5th to overtake a triple, it pushed me into the seat, now I am impressed, very happy

I thought that the cetane levels in Australia are at 46 in order to comply with government regulations as per this document:

Apparently the cetane level in Europe is 55.

Re: 1zk-te vs 1kd-fte

Like all technologies, there will allways be something beter around the corner. I would imagine that as the D4D Prado was first rolling off the production line, there is a better, more powerfull and more efficient motor on the test block right now. lets all be thankfull for what we have, not every one can keep up with the Jones's and have the latest and the greatest. At the time the 1zk-te was released I bet every one rushed in and thought they were getting the best. Who can tell whats around the corner. I can't see why there is a point of trying to compare all the time. On paper the D4d is obviously a more efficient motor but each to their own

Re: 1zk-te vs 1kd-fte

I think Toyota tries to make a careful assessment of diesel fuel quality in each market before it releases a product.

In Malaysia, the D4D motor was released long before it was brought into Australia, and many Malaysians had issues due to poor diesel fuel.

In South Africa, the 120 Series Prado is STILL with the old motor. In fact, even the South African market for 76 series wagon (which has the 4.5 single turbo V8 diesel motor in AUstralia) is still in the dim dark ages of the 1Hz motor, in non turbo format. At least they have a very big wide engine bay now.... :mrgreen:

Re: 1zk-te vs 1kd-fte

Here in Brunei, SE Asia (Borneo), they are still using the 1KZ-TE in their latest Prado's, despite the Hilux and Fortuner being fitted with the 3.0l D4D.

Had mine for a year now, (from new) goes great, but would have preferred the D4D...

May have to fit a Dtronic or DPC Chip for a little better acceleration.....but which one? :?

Re: 1zk-te vs 1kd-fte

Greetings Bonno,

I was born in Brunei!

OK, just for a few giggles, do tell everybody what the price of diesel in Brunei is per litre. (Brunei Dollar is around 0.96 Aussie Dollar so very similar)

I was recently in Thailand and saw just heaps of Fortuners and Hiluxes and Hiaces, all fitted with the D4D motor. Interestingly, the Hiluxes in the older, superseeded shape were already boasting the D4D motor, so it's been in "service" for quite a while now. I'm surprised that despite all this, the Prado in Brunei soldiers on with the older but reliable motor.

Interestingly, I used to live in Melbourne although it was a very long time ago...

As for the price of fuel, I'm not sure anyone would believe me!

Ok, it's 0.31c a liter, I always get change from $25 when it's filled up from near empty...

The Fortuners here are Thai assembled, in fact it was my original choice, but after comparing the ride with the Prado, the Prado was a lot better. But then I believe the Fortuner is based on the Hilux chassis, so the ride was a little harsher. However, what swayed me was the lack of good aircon in the back seats of the Fortuner (very important when it's 30+C almost everyday), as it is located in the luggage area in the rear at about the top of the wheel arch, whereas the Prado has the regular vents above the doors. So any bags, golf clubs etc, etc is going to restrict the airflow.

Having said that, it is about $25K cheaper than the VX I ended up buying, but no regrets with the Prado though. I have to say it rarely goes off the road, except on Wed nights at the Hash (that's another story) but we drive it to KK and back fairly regularily and it certainly makes for a comfortable ride. BTW, don't know when you last did that drive, but the road is sealed all the way now...

Re: 1zk-te vs 1kd-fte

I can only compare the D4D to the old 3L and 5L motors. I used the drive the old 90 series Prado (I think it was a 3.4L petrol) for work off road for work a few years ago and I wasn't impressed with it. It was sluggish and had no bottom end torque. The torque was the prblem where I was driving. Very slow rocky areas.

As for the 3L and 5L motors, they are bullet proof, but take some skill do get the most out of them. About 2 years ago I had a contractor of mine swap my work 5L Hilux for his F250 ute for a project as his F250 4x4 kept on getting bogged while the Hilux had no problems. It turns out that the 4x4 electronics were faulty (on a new truck) but he still wouldn't have managed in the mud.
