D4D 3.0 to replace KZ-TE 3.0 in Double cab

[Bushcrazy]

My 2000 3.0 KZ-TE on 200 000km just now blew the cylinder head gasket. Estimate repair costs received were between R13k to R18k without the engine open which may increase the quotes. I also heard that after such repairs the engine start to use oil and other components like turbo, oil pump etc most probably will also need to be replaced on the 10+ year old engine at a later stage which make the repair not looking very economical.

I am thinking to seek a good second hand low mileage 3.0 D4D (Complete engine, gearbox, EMU and harness) from a write-off insurance claim which apparently can be bought for less than R40k and to have it installed in my 2000 model D/C.

Do anybody know if such a conversion has been done, where I can find more information and contact details, any complications/difficulties and expected outcome

Hallo Herman,

Enige iets is moontlik - mits jy genoeg geld daarna kan gooi!

Voor jy 'n ombouing doen, maak jou somme mooi, maal dit met drie, maak jou kar reg, verkoop hom en gebruik die geld wat jy vir die ombouing wou gebruik om nou die voertuig met die enjin klaar in te koop. Maklik, problem solved!

[Bushcrazy]

Dit is `n opsie maar huidg het ek geen skuld op die KZ-TE en is die voertuig aanvanklik deur my gekoop. baie mooi opgepas, al sy dienste gereeld gekry en was nog nooit in enige ongeluk nie.

Maak ek die voertuig reg @ ongeveer R15 000 (Min geskat) en ek verkoop die voertuig weer vir R110 000 (Inruil was verskaf teen nuwe DC @ R87 000) is my kapitaal beskikbaar R72 000.

Koop nou `n nuwe of goed opgepaste 2de handse voertuig sit ek weer met baie skuld.

Maak hom reg. Ek het myne reg gemaak, en hy gebruik nie olie nie, sy turbo is nog reg na 9000km en hy trek soos nooit te vore nie.

As jy D-4D gaan kyk na die Fortuner ratkas. Permanent 4x4. Kry 11.6Km/L

[Family_Dog]

Maar Gert, wat kry jy as jy nie gesleep word nie...?

Moet jy dan nie ook die voor diff vervang nie? Permanente 4x4 en die voorste diff heeltyd gelock, gaan dit nie lol nie?

Ook sit nie d4d se kort propshaft aan die verkeerde kant vs die IFS s'n

Dit is `n Toyota Hy sleep. Hy word nie gesleep nie.

Get Fana to make you a belhousing and fit a D4D, its a far better motor and way better fuel consumption that the Kzte. It can definitly be done, otherwise fit a lexus. I have often thought of fitting a lexus to the Kzte as the gearing is perfect for that moto and I think the fuel economy will be pretty good as well.

[Bushcrazy]

Hallo Gunta

Yes very attractive options

The fitment of the D4D drivetrain will be relative easy but the electronics we see as the challange.

Any idea of somebody that did such an conversion or that can be recommended for the eletronic/ wiring part?

[Gunta]

Depends on if you are using the original ECU or going aftermarket. Personally I would go with the original. Any auto elec would be able to tie in the ecu into your harness with ease. I had mine done and it cost me 2k otherwise you are going to spend 5k going aftermarket.

[Bushcrazy]

Hallo Mark

Thanks for the advice.

No I want to use the Toyota D4D and not any aftermarket system.

I saw on your profile you have a 1995 DC with accessories.

Did you do the D4D into this vehicle?

What is your overall feeling, like fuel consumption, power, ease of the conversion?

Didn't you run into problems with the D4D being a bit higher and the intercooler on top of the D4D a problem in your vehicle?

Did you also install the scoop on your vehicle for the intercooler?

[Thabogrobler]

Herman,

Mark has the 7MGE motor in his 'lux - the old 3 litre Cressida motor - But it is still a very nice truck!

AFAIK no-one on this forum has put a D4D into anything???

[Bushcrazy]

Hallo Thabo

Yes I think you are correct as the communications are all around the D4D, everybody believes it will be a super conversion but I can't find somebody that has attempted it up to date.

I have registered this post on the Land Cruiser and Mud forums, who knows maybe I do find somebody that can give some guidance.

However if not I may repair the KZ-TE as cheap as possible, seek a good D4D drivetrain with all bells and whistles and then remove the KZ-TE engine and sell it off and start the D4D swab.

[Thabogrobler]

There is no way that a engine swap would be cheaper than a proper repair!

And think of resale value - will you buy a vehicle with a different motor in? I would not easily part with my money for a conversion, unless it has been proven before.

[Bushcrazy]

You are correct. An conversion swab-out will cost between R45-50K and the resell of KZ-TE drive train R10-15K. Meaning that it will cost on the long run between R35 - 40K but then you have a relative new motor, much better power and fuel consumption.

My 2000 KZ-TE body is in an excellent condition and if I have to buy a new/later model DC will I again have a lot of debt.

My idea is not to convert and to sell but rather to upgrade and keep enjoying the same vehicle.

I also think if I want to sell somewhere in the future the person buying the vehicle will also have done their own homework and will have to compare prizes to what is available.

[Gunta]

I dont think you will have a problem selling it with a D4D. I would do the swap if I were in your position.

[bosjakkals]

I would deffinately fit the D4D, as I understand you dont even need to swap bellhousing as the KZ, KN and KD engines share the same bellhousing.

Maybe you would have to mount a scoop on the bonnet

Go for it

[Bushcrazy]

Fitment again will be easy. The problem is the EMU.

[Gunta]

I guess you mean ECU. You can normally get one at the scrap yards with the engine.

[Bushcrazy]

ECU.
Yo have it tied into your normal vehicle electronics which is the problem.
Aftermarket petrol ECU's is not any problem but with diesel you have to use the manufacturer's EC.

I even heard that the ECU can control ABS etc and the old ABS and what is installed in the D4D isn't the same.

I am just scarred to purchase the D4D have it installed and then not be able to get the engine to fire and talk to all other electronics in the vehicle.

I can't get anybody on any forum that installed a D4D but many installed petrol engines etc.

[Mr_B]

Herman, get the KZ fixed up. Allan Venter has been talking about fitting a D4D into a SFA for a while, but the engine remains too expensive for it to be a viable option!

Hi All

I am also looking at swapping KZTE for D4D....

Has anybody done this convertion yet? My KZTE engine has serious damage due to stupid mechanic, and i now have cracked slleves and c/head.

Please provide me with details of trustworthy guys who can assist with the conversion.

[Gunta]

William phone Japan auto 011 397 6789 and get a complete motor from them. You will have to try and source a wiring harness and management system from a scrap yard and then buy a bellhousing from toyota and the get a mechi to fit it for you.

I have a complete block(with crank, pistons, etc.) for you!

[J.C Avis]

Ek het ñ nuwe topic oopgemaak en nadat ek afscroll sien ek jul topic! Ek dink ook sterk daaraan om dit te doen,rede,bakwerk is sterker as die nuwes en ek het baie ekstras al gedoen op hom. Ek wil my ratkas behou,kan mens nie die sac intercooler ook behou en modify op die Kd nie? Dis net die wiring wat my pla. Die Kz se ratio is baie na aan die Kd,en ek glo as jy die Kd engin chip...baie krag met goeie brandstof gebruik!

Good day. My 3.0kzte double cab 2×2 fills the coolingwater reservoir up with water after 2 hrs drive and overheats. I changed the radiator, thermostat and waterpump with new. It's still doing the same. What else can I do. 385000kms.

Typical symptoms of a cracked cylinder head. Buy a new, bare head at Alert Engine Parts, have the cam and valves build over to the new head, get a TOYOTA headgasket and a 74 degree thermostat. And all the usuals like timing belt, tensioner, waterpump, etc.

Also, very important, have the radiator chemically cleaned and tested for flow rate.

Do it proper, then you only do it once.
