I Have had a problem with my 94 2.8 diesel hilux. The motor is in a million pieces. Number 1 piston picked up on the cylinder.Oil was changed every 5k but obviously not enough.
My querie is can I replace the motor with a Jap import 3l turbo as in the surf and the new hilux. Does any one have any experience with such a conversion. I was thinking of buying a half cut and fitting motor, gearbox etc . I believe the 3l wont bolt up to my gearbox
Any coments or assistance welcome

I haven't done it but it is the same motor as used in ours. It is a 1KZ engine.
The gearbox mismatch I have been told before is because of the different flywheel used and the mismatch for the spiggot bearing. I presume a machinist can overcome it or go with the aussie flywhell and clutch which would make more sense but this is going to cost dollars and I suggest you look at aftermarket flywheel and clutch unless your a millionaire then go to toyota.
Others may be able to enlighten you more on this as I only looked in to it briefly.
By the way the injector pump needs dollars spent on it as well because the 1KZ item is an electronic item and has to be converted to manual operation and it will not quite perform as good as the electronic setup. I don't know if the 2.8 pump fits but I doubt it very much.

I believe if i buy a front cut it comes with engine control system gear box and realy the whole front of the car minus panels.
Mine has a live front axle and again if i can do it would change the whole front suspension to independant suspension. Big job i know .

IFS is fine for all but rockhoppers, you want an axtra 1" or so or yep it's worth it but for most of us IFS is an improvement.

Good luck with it. It is a lot of work but that engine leaves the 2.8 for dead.
When I looked into it the 1KZ was not in the Aussie vehicles it was the 5L 3.0litre
so i baulked at the prospect worrying about parts but I should have if i only knew. I went and rebuilt the 2.8 instead and put a DTS turbo on it after I run it in. Not as good as the motor you are looking at but I will never own a non turbo again it's magic for torque.

Thanks for the advice
one of the uses for mine is towing a horse float, i think that may be part of the reason that the 3l fell to pieces after only 160,000 km. .THe other option is to do what you did. I think the 3litre is a more sensible option for me. The price for second hand 2.8 motors seems very high to me,

I paid $3500 for the reco engine and another 3 for the turbo with new two and a half inch exhaust. That will give you an idea of the cost.
Make sure you price all the bits like flywheels and any other extras and check it out thoroughly. you will be surprised how much the extra cost. Try and get a firm quote in writing for the job or be prepared for the odd headache if you do it yourself. I know, i was once converting Yank cars from left to right hand drive and even the ones that were supposed to be simple would sometimes be difficult. Best of luck dude.

Bill,
Not wanting to spoil your fun but there is a lot of other stuff around fitting a bigger engine with more power, unsure where you are in Oz but just do a bit of homework with your local licensing centre and also your insurance company, I did due to prompts from this forum I'm now sticking with what I've got, for now (hubble, bubble, toil & trouble) I don't know what the strength issues around the rest of the drive train are but it's worth checking unless you're beefing up everthing for the transplant. All sounds very good but i would just check a few things out first. Good luck.Keep the shiny side up

Martyn,

Hubble.bubble,toil and trouble...let the cauldron boil and bubble..........and the "Out out black spot"...............

The memory fades...that is all I can remember from MacBeth having been forced to study it at school in the 1950's(Good grief..that's a while ago!)
Cheers,

forget all the problems with the injected diesel and put in a commodore 3.8 V6 very common conversion. Call Marks 4wd adaptors. I think all up about 5k and the wiring is compatable to the toyotas black box so i,ve been told. Have fun

Problems with injected Diesel?

Theres a bloke on the Melbourne list who did a Marks Adapters kit with a VS Commodore V6 in a 4 Runner, nothing but hassles.

$14k he was last cost that I heard, and its still not right.

Yep
Why put a commodore v6 in when a 7mge Cressida motor will fit straight in (almost-they never fit straight in) Mounts, gearbox etc.
Check out this site for some more info on the diesel transplant. www.outerlimits4x4.com
I would see if you can get a whole front cut from an inporter or even better, buy a rollover for a few $$ and sell the parts you dont need to break even :-) www.pickles.com.au

Gday Bill
I had a 3.8 conversion in an 84 dual cab,you will see it getting around armidale.
Went like the clappers, got 18MPG empty or loaded and devoured driveline components.
A good bolt in for yours in my book would be a mechanical pump 2LT import. About $3500 done yourself with new clutch and exhaust. They are plenty strong enough, we put one in a 4 runner and it will pull out of halls peak in 2nd high.
I could organise a test run if you like, see for yourself how it pulls.
cheers brian
