1zk-te vs 1kd-fte

[pml120r Junior Member Find all posts View Profile Close pml120r]

just would like to know , why alot of you guys rubbish the 1kz -te engine ? And how many of you have had a 1kz-te before the 1kd-fte? :twisted:

A lot of the d4d owners here have moved up from an older diesel.

I dont follow the engine numbers but I gather thats what your talking about.

Having driven both, its like chalk and cheese to compare, power to no power, average fuel economy to good fuel economy, less torque to more torque, poor overtaking to good overtaking. etc.

A search will bring up dozens of threads on the different engines and their abilities.

Oh and moved to the right section. Mod.

:? well said , but both engines have the same torque ! the 1kd-fte has more power yes ,so why bag out a reliable engine.
I am gettin about 10l per 100km around town out of old engine! what fuel figures are u gettin out of D4d engine?

[Guest Close Guest]

Might need to check your figures I think...
:?:
32% more power (dealer specs) 96kw vs 127kw
20% more torque (dealer specs) 343nm vs 410nm
19% better fuel economy (my actual increase between 2003 td auto and 2007 D4D td auto still with low km on the clock) 12.8l/100km vs 10.4l/100km

(Note the above is copied from another thread here)

I have seen fuel figures around the city driving real easy in the 9.5 L per 100 once personally. Hwy is always about 9-10 per 100.

Whos bagging ?? its in a Prado so all is good :wink:

I have an early 04 model, back in those days there was no such thing as D4D, I bought the petrol one because I liked the grunt, sure it uses more fuel but you get that !

Wagga Wagga...hmmm sounds familiar....


Anyway as a 1Kzte owner/user I can say that its a big improvement over my last Toyota engine.... the old faithful 6cylinder 2H.

Hills that resulted 3rd gear & 60km/h now result in 3rd gear & 100km/h over the top, & thats using the 4 speed auto too.

On a recent trip back from Sydney, many hills resulted in a close to 100km/h speed when the cruise control was still requesting 110!
In addition, I was able to pass several small 4cyc petrols...not many, but a few!

One very slow car was an older troopy.....they definatley don't like hills at freeway speeds.....they are certainly underpowered, but ideal off the track...much like my old 2h HJ60 was.

A D4D would be nice though....I have my eye out for a DTronic incase one happens to come my way.....

Never had the old Diesel motor.

But went regular beach fishing with a mates Hilux (old shape / old Diesel). Really struggles above 120, i.e. overtaking. Has to rev the guts out of it in all gears, and quite a fuel sipper as well, 13L / 100km.

Sand driving in the manual was a mission. Has to red-line it before changing up a gear, losing all momentum and bogging down in the next and it takes another minute to get the revs up again. Having to slow down is a nightmare, stay bogged down in the current gear or swap down, losing even more momentum....

Other than that, 5 people, with back fully loaded (canopy) and towing 1ton up North and it keeps going on. Pretty bulletproof motor.

Geez auto's are great in the sand.

Mind you, I know I'm getting fussy, but the Prado should really have a 6cyl Diesel pumping out more like 150 - 160kw. The 4cyl should be more for something like a Rav4, which in overseas markets they do come out in Diesel, even the Corrolla is in Diesel overseas.

Only the 3 of us that im aware of Stormy

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.

Mark.

go the d4d

The "old" engine may not be powerful but it probably is more reliable in the bush as it is "older" technology.

I would even say that that the old motor is probably a little more tolerant of low quality diesel.

I have the old oiler , can't afford the new one have to pay for it up-front no leases. Does a good job , gives adequate performance and fuel economy, D4D would give better overtaking ability and most importantly longer service intervals .
Got to admit that on a day to day basis that I drive a fully laden 4.2 Patrol (3.5 tonne) so I have lots of experience of getting the best out of these type of engines do around 1500-2000k /week on some of the most testing roads (on off roads ) that your likely to test the performance limits on . Don't have any trouble keeping up a good average ,what you loose up hill I make up on the corners etc . The Prado feels like a rocket ship in comparison !

I've got the old oiler. I can confirm Lawrence's comments about tolerance of crap fuel. I live in remote WA and our local mechanic has replaced a few fuel pumps from D4D Hiluxes, but has seen no probs with the older engine. I suspect that this is associated with the small tank in the HIlux leading to jerrycan use, rather than dodgey fuel from the roadhouses. We have our work Hiluxes fitted with long range tanks and a "no jerrycan" policy to circumvent that issue.

Having said that, I'm sick of my lo-tech sludgebox and am gonna get me a D4D. Does anyone make a diesel with an injector pump any more? We're talking last century technology here and Toyota have well and truly tested the D4D in the Hilux, prior to fitting it to the rest of their diesels. I do too many kms to ignore the saving I'll be making with the 10-20% better economy of the D4D.

And you'd be surprised just how many caravans, corners and hills there are on the Stuart and Lasseter Highways when you're driving the SLUDGEBOX FROM HELL.

Still better than my 79 series ute tho.

Seems like Toyota are experiencing problems with the low cetane level of diesel fuel in Australia, and may have to detune the D4D motor to cope with the lower fuel grade.

Seems like the D4D, in it's higher state of tune in the Prado, can experience knocking, but the same motor in a lower state of tune in the Hilux and Hiace do not seem to exhibit the same issues.

So the power and performance of the D4D may be it's own undoing. ops:
