I must say even though I have ageneral dislike in any diesel engine these 2.5 TDI Ford/mazda engine is the one I would use if ever forced at gunpoint to select a diesel engine for my car, but that said I still think diesel stinks :twisted: :twisted:

I have to disagree with you guys, these engine have an overheating problem, the cylinder head cracks, it is a known fault with them.

One man's meat is another man's poison, it all depends on how it's fitted.
Do you think it cracks more heads than Toyota Turbo motors?
The power curve and higher rpm suits the hilux better than anny other diesel motor.

I agree with Bennie, it is a diesel thing, even the old 2.7 turbo diesel Nissans is cracking heads. And I do not think it is a fitment problem because those 2.5 engines even crack heads in their own original vehicles.

Ford/Mazda engine in 'n Hilux? Dit is verkeerd 'n mens het darem seker meer respek vir jou Hilux as dit. Hoekom 'n turbo diesel Toyota/Ford/Colt, hulle is onbetroubaar, het nie/of maar min bottom end,as die turbo inskop (rondom so 1500-2000rpm) dan het jy weer teveel krag/spoed dan verloor jy weer tracktion en hulle loop warmer as 'n normal asperated engin.
Soos die brandstof prys nou gaan sal ek(as ek jy was) eerder gegaan het vir 'n petrol engine, hulle kraglewering is meer gelyk, hulle ontbranding is skooner petrol is goedkooper ens.ens. ens.

I am working six Years at McCarthy Toyota selling plenty of KZTEs and have seen only one cracked head on a KZTE in six years. So cracking heads and blowing engines is NOT a Toyota thing. The KZTE motor in my opinion is the most reliable Toyota Turbo diesel i have seen. They go on forever.

So do not mention Mazda, Ford , Nissan, and TOYOTA in the same sentence. I know the truth. Toyota does not belong there. KZTE rules. FULLSTOP!!!!

marius safari WOW, You sure get uptight man :lol:
If you read the above thread correctly, you will see that we were refering to the older 2.8 diesel engine, and NOT THE KZTE

So now we know that we have a person who works for Toyota and thus we have somebody who can supply us with parts at great prices, why do you not ask Toyota to advertise here on this web site?

However I would like to know how many of the vehicle's that you sell you actually see after the 3 year or 100 000km garantee or warrentee is up back in your workshop for repairs?

Tell us some news about the gearboxes in The KZTE and the 5th gear.?

And one last thing, you and I have something in common.

We both work for the same group Bidvest :lol:

Marius Safari, ok the KZTE motor is not to bad in the aspect of cracking and blowing heads, but howmany 2.7i Hiluxes do you guys open? I know for a fact that we have only opened one 2.7i motor in the last 5 years and for the KZTE motors we must have opened about 4-5 of them.
If you kan recall how many 2.7i to KZTE's have you guys sold.
We sold about 7 Hilux 2.7i's to every one KZTE. Reason for that the fuel consumption and driveability was about the same, but the KZTE is much more expensive to buy and keep on the road.
I have been in the motor selling game for about 10years and I have plenty of 2.7i Hiluxes with 300-400 000km on the clock with their origanal motors in them without being opened. I cant say I have seen a KZTE with the same kind of kilos on it that has never been opened.

Most of the facts are correct, you either love or hate diesels, i've never driven a succesful KZTE in an SFA Hilux.
2 problems; the gear ratio is to high, the KZTE is not a free revving motor and its not happy at high rpm, i drive one myself
The mechanical diesel pump swop robs it of its power and you batle to fit a fan and radiator that's large enough.
The 2.7 is the easiest and most reliable transplant, but you have to use a good management system or carb setup.
The 4y is said to be one of the most reliable motors, but they are underpowered, they blow headgaskets and they wont last beyond 250 000 km when driven hard, but some still swear by them.
I serviced a 2.5td WL motor with 320 000 on the clock, unopened and i've seen a few with 250 000, it all depends how you treat it.

And what are your feelings about the 2 L 2 motor, we have one in a vehicle at work, it gets abused by everybody, sometimes pulling a trailer all over South Africa, the engine has been opened once for a complete overhaul, the vehicle is a 1998 model, the start of the new body model for that year, this vehicle has done 780 000km.

Please note I am not one of the people who dislikes diesel or petrol engines, it all boils down to how you look after each vehicle and abuse it.

4Y 2.2 petrol carb
7MGE petrol fuel injection
4Y 2.2 petrol fuel injection
2.8 non turbo diesel

These engine types are the ones that we use in our four Hiluxes that are running.

Other 4X4 vehicles have.

Yes Simon it's thats best motor ever built, i sold my 2L with 760 000km on the clock unopened, but fit a turbo and it won't see 100 000 when driven hard.

I know it's not "nice" to fit other motors in a Toyota, but the first Turbo Diesel that Toyota built that's a succes is the D4D and it's not affordable yet.

I think its always better to stick to the brand I also toyed with the idea of fitting a BMW M52B28 328i 154kw or M54B30 330i 170kw. However I changed my mind as its not a Toyota motor I think when my ship comes in I will fit a 2.7i motor with the Toyota electronics.

I drove a Mazda Drifter X for about six months two years ago, and I was not impressed with power delivery at all. Also, I always got 7 kms a litre.

I don't think that this conversion is worthwhile. The 7M-GE gives 6.5km per litre, is a toyota engine, and is a far superior engine in terms of reliability. (and cheaper)

2 years down the line since I replaced my 2L with a 5L engine, I can kick my own butt! Although the 5L is a great motor to have in the SFA, I wish I did the sensible thing and built in a petrol motor!
I really do not trust the 5L anymore after a few instances of overheating, without even working the motor that hard. The short and the long is I do not trust the motor to do a long trip...

Wonder, how hard is it going to be to swop out the 5L for the 22R that I have??? Wiring, cost etc.....

But it also depends where you want to use the vehicle and you do have the 22 R for now, if I was you I would just drive the vehicle with the 5L until it is worn out and unreliable and then fit the 22 R back in and when you do the fitment, you will see what it costs, but in the meantime if you have the extra cash, just put some away in a seperate account until you do the engine swop.

Kom ek gooi 'n spanner in die wiel, ek het sowat 4 jaar gelede die Okavango Delta met 'n Ford 2.5 tubo diesel aangedurf, 'n 1999 model. di ding was stock std behalwe vir die daktent en extra petrol tenk. Ek het 5000km gery in modder, sand en water. Gemiddeld sowat 3000km offroad het dit my 8.1km per liter gegee en op teer 12.1km. Die frustrasie partyker was om vir die ander te wag by elke vulstasie oppad dan was ek of half of kon nog 200km ry. Die range met die 2 tenks was 1100km gemeng tussen 4x4'ing en teer. Die "Fordjie" het 220 000km op die klok gehad. Ek het 'n bietjie respek gekry vir die ding want 2 van die Colts het on baie probleme gegee wat saam was.

Maar ek laaik nog steeds my Hilux 2.2l EFI BBBBBBBAAAAAAAIIE meer!!!

Groetnis,
Louis

Spoken to a guy who have many years of experience in modifications. And what he said made perfect sense to me.
He said that the 2.5 Mazda engine is a good conversion for the SFA Hilux since everything sits on the right places. The inlet and outlet manifolds, the alternator, the waterpump, everything is where it should be. It also has an build in power steering pump.

Apparently the engine also revs higher than the KZ-TE engine which makes it more suitable for dune driving.

As for the cracking of the heads he said that all turbo diesels will crack their heads if not looked at properly. Apparently the exhaust runs at about 700 degrees and when it hits 800 the head might crack. So it is running at its limit all the time. So it is important to make sure you cooling system is always in good shape. What some guys do is to fit a turbo diesel engine in their SFA but keep the old radiator. Because it then do not gets the cooling it should they get problems with the engine.

He also said that he has clients who have done more than 300,000 on their 2.5 Mazda Turbo diesels.

Thanks for that info Piet. What about the gearbox, is the old four speed good enough or must we match the engine with the mazda 5 speed box as well

Eish I see my answer was posted almost 5 years ago.
I am not sure about the 4 speed box but I know they rather keep the Hilux 5 speed box than the Mazda box.
Hoppy will have better info on the 4 speed box.

In many cases even the Ford and Mazda guys convert to a Hilux or Cressida 5 speed box because it is more reliable. So definitely you wont keep the Mazda box, only question is if the 4 speed will be Ok or if you will have to look for a 5 speed Hilux box.

I can say one hing. The 2.2 4y is a "ou staatmaker", even if its a little bit thitsty. When I gor my van a while back it gave me 4,5 kilos to a litre. After a dyno and carb overhaul it went back to 6,8.Although I'm working for Ford and the WL motors are discontinued, you can pick up a brand new motor at a dealership for R12000. My Mazda 2.5 i drove bfore my 2.2 gave me 9.8 kilos er litre.

hi pieter , if you look at the cruiser guys the most fit a alarm system for exhaust gas temp ( madman / mgl avionics R) , not more than 650 / 680 deg , but you dont see them on the wl or kz's i think this is where the failures come from , all you need is just a small buzzer just to let you know back off a little im too hot.

It's a good proven conversion, you have to use the 5 spd, there is no "off the shelf" bellhousing for the 4 spd

We have fitted a few on the KZ/WL conversions, i was surprised to see how quickly the temps shoots to 1000 deg, like you said. I t's not a bad motor if you look after it

EGT of around 720 deg C is considered to be the highest value allowed on sustained driving.

Fit a Madman or similar monitor that will keep an eye on your EGT probe and your coolant/water level.

The WL25 is a great little engine. Way better than anything of that size from Toyota :o:

Just want to add my 50cents worth,

I did the 2,5 mazda conversion on my sfa,had a 22r in which was a good engine but under powered and fuel guzzler. Hoppy helped me with a lot of info(although i have done some conversions)i got all the right info from him....i can say this,this was the best conversion that i could have done...25k later all done.enough power,gets 9,4km/l in town,round about the same on the open road with no trailer.and 8,3km/l on the open road with trailer,canopy and 4 people.on the open road on long uphills the heat gauge lift about 3mm.on heavy/sandy 4x4 roads with trailer and low range driving the heat stays constant!up till now this conversion has done 28000km in my sfa and not one problem. i bought original clutch,pressure plate,kzte radiator,good quality viscous and fan..etc and everything is solid and good!this is a straight forward engine with no electronics sensors and electrical pump,making it most reliable.our route this desember is over 4000km and 4 country's and knows my lux wont let me down...

just look after the engine...like every other engine

thanks agian hoppy for the info
