-----------------------------------------------------------------------------


Hi all,

Just got myself a written off new 79series with the plan to transplant the 4.5V8 + gearbox + transfer into my 100 series (Rigid front, 1Hz) turning it into part-time 4WD along the way.

Is there anyone else thinking about this, or maybe even done it already?

I'm not too concerned about the mechanics of the conversion. I'm pretty sure I can get it all to bolt in alright although I may need new diff ratios.

My concerns are with the electrics. The old 1Hz has all of about 5 wires running off it, while the new electronic V8 has a 2" loom! I've got the entire loom and ECU from the 79 but I need to work out where I need to connect what etc etc. I'm thinking the immobiliser, gauges etc could present some problems.

What I'm really looking for are CD copies of the 100 series parts catalog, and the 79series parts catalog, workshop manual and wiring diagrams so I can check compatibilities and see what attaches where.

If anyone can help with either the CDs or any helpful advice, please drop me a line.


Cheers,

Jamie

hey mate. not sure if your aware but the only reason toyota upgraded the look of the newer 70 sereis was to fit the new engine wich required the chasy to be widend signifiganlty.
toyota stoped building diesel landcruisers in 07 awaiting this new motor.

i hope it works out for u as it will be the 1st conversion but dont expect it to be easy and the motor may not fit in ur chasy rails at all.

should still fit in a 100series tho.

as with the electrics, good luck lol

I'm pretty sure it will fit the 100 OK, as there are plenty of big Chev diesels in 80s and 100s. I'm pretty sure the 4.5 is no bigger than one of those. I know they had to widen the 70 for the new V8, but they were much narrower than the 80/100.

No illusions about it being easy, but I like a challenge!

Do you have the complete 79 series wreck? If so it would possibly be easy enough just to tear it apart and study what goes where. I would think 79 series wiring wouldn't be overly complex, say compared to a 200 series.

You can buy workshop manuals from a dealer, but they are expensive. Not sure about a parts catalogue. A gregories type might be enough, if they are available yet

Where did you get it from anyway and how many kidneys did it cost? I'm very jealous. I had contemplated the same conversion but figured the cost of even a wrecked 79 (let alone a 200 series) would be prohibitive.

it is very doable just use EVERYTHING from the 79

they only widened the ute chassis........ same chassis they used in a 1985 hj75, i recon from my limited looking a v8 would fit a 105 series but the turbo will foul the ifs on a 100.

id never even contemplate it with a 200 tho even tho the motor is far far superior to the 79 single turbo.
the 1hdfte is muchly superior to the single turbo v8 and will bolt in, just wont sound like a v8 or be as cool to tell ya mates.

ive driven a 1HD-FTE powered 79 and a 1VD-FTE powered 79 and the V8 blows the straight six out of the water without any problems at all.

Its a monster of a donk- and DP chip are already claiming you can get 175kw/535Nm out of them with just a chip!

ive driven both too. and to tell the truth the 1vd went marginally better but the fte in a 79 is the non intercooled version. I actually thought the thing that made the biggest improvement with the new 79 was the extra width made it drive nicer

i didnt say it had more power just it was superior. the early single turbo 1vd's had cylinder bank balance issues due to the 1 turbo and are not a proven motor yet. they also wont bolt straight to the engine mounts, nor will the cooling lines and everything else line straight up in a 100 series
toyota didnt get rid of the 1h series for any reason other than emissions

Hey Austmages;
If you have no use for them, I may be interested in the crownwheels and pinions out of both diffs.
Shoot me a PM if you are interested.
Pony

loaded or unloaded? Hills or flat?

Loaded on hills, the new common rail donk pulls away all the time from the old one.

Austimages,

Give Jason at Total Care 4wd in Seven Hills a call 02 9838 9779. He's doing a lot of motor swaps with the 1HDFTE into 75's, 80's, 100's and even a Patrol. He'd be keen to have a chat about swapping the 1VDFTE into a 100.

I have done quite a few of the 1hdfte conversions and the 79 is a much easier option than the 100 1hdfte because of multiplexers and imobliser systems
i have done 1 100 series 1hdfte into 80 series 1hz it required a bit of fiddling to get it to run due to the immobiliser you will also have to fiddle the tacho using a tacho from a petrol i changed the resistor values inside the tacho to alter the voltage divider network although in this case it may be easier to remount the new tacho in the 100series cluster because most toyotas run a 4cl tacho on there v8s

i unpicked the eng loom wire for wire and made up a new fuse box etc to run the efi plus ran new looms for the immobiliser and cruise control and fly by wire accelerator pedal and demultiplexed the whole truck runs great it is my family hack have put about 50000 km on it

it will be money well spent to buy the toyota body electrical manual and the engine book they are far superior to any other source of information you would be looking at less than 200 bucks for the two
that is a lot cheaper than going to ashley and martin for a hair transplant

I have in the past made up simplfied stand alone looms for people so all they have to do is mount the hardware and run the looms plug it in and connect battery ignition and start

I have done a few for !kz conversions also same deal
its all the same once you enter the world of efi

best of luck

i cannot see this engine presenting much dificulty there are always ways around things you just have to think of them

Sorry, I'm going to swap the crownwheels/pinions into the 100 to get the taller gearing.

Hi again all. Just thought I'd give you an update....

I had to put it all on hold for a bit, but I've just started back with it now. I also had to do some repairs to the V8 (from accident damage), and I wanted to start it in the 79's chassis before I did the conversion just to make sure it was all OK.

At this stage, I've fixed and run the V8, removed the ancillaries, the wiring loom and the transfer case. I'll be lifting the V8 and box out of the 79 next week.

So far, it all seems to be feasible but it's not going to be easy.

The 100's chassis is slightly narrower (~40mm), but that shouldn't be a problem as there's plenty of clearance. I'm keeping the gearbox out of the 79 as it's stronger and it has a long bellhousing to push the V8 forward in the engine bay. I'll be attaching that to the 100series transfer case to retain constant 4WD and ABS (Without constant 4WD, the 100series ABS is disabled). There may be some minor panel work required to fit the engine in the bay, but I'll have to cross that bridge when I get to it. I'm also going to lift the diff ratios by swapping the crown wheels/pinions from the 79 to 100 diffs.

I'll be installing almost the whole 79series wiring loom in parallel with the 100series loom, and then just connecting what I need to. I decided this would be the easiest way to integrate the two looms. Basically, the 79's loom will run the motor and the 100's loom will run everything else. I expect some issues with gauges, but I'll have to wait and see.

Unlike the older 79's, this one has the full Toyota electronic immobiliser system fitted to it. Same one as the 200 series. I spoke to a locksmith, who advised the best way to do the immobiliser will be to have a Lexus key cut to the 100's ignition barrel, and have it programmed to the 79's immobiliser ring. The 100's key won't work the 79's immobiliser, and the 79's key won't fit in the 100's barrel.

For anyone else interested, I recommend keeping an eye on the salvage auctions and buying a whole written-off car, rather than buying the bits from a wrecker. I paid $10750 for a whole car. A wrecker I spoke to wanted $15000 just for the motor! Check out manheimfowles.com.au and pickles.com.au for info. You can set up a notification system that will email you when a vehicle you want is listed. Another advantage is that you'll have the 79's parts to sell afterwards to get some of your money back.

I'll keep you posted as the conversion progresses.

before you go to that trouble with the keys try duct taping the 79 key under the dash and wireing up the 79 loom to the 100 barrel then using the 100 key to start the car

this is what they do in cabs cause the drivers always lose tyhe keys at $200-$300 to replace.

Yes, I could do that (A Toyota mechanic I know suggested that a while ago). But then I wouldn't have an immobiliser. I don't mind spending a few hundred on new keys after all the time, effort and money spent on the car.

Could just put the 79 series key on the same keyring.
Still got immobiliser, no-one will know what that other key is for anyway

if you still need the genuine toyota cd i *MAY* be able to help.

i'm not putting it out for everyone as it's not really good for my job ,
but i like the sound of the conversion so pm me and i'll see how i go

You are right, the 100 is a fair bit wider than the 75 so it will fit.
No worries. ALTHOUGH the Toyota V8 is a 90 degree V, and is physically bigger than the big Chev diesels you mention. (6.2/6.5L) Its physical dimensions are bigger, the heads are taller, the intake is bigger and the V is wider.

You will make it fit, good luck with the conversion, I would love to see pics of it all underway!

I tryed both of these options when i did my 100 s turbo to 80 conversion

it did not work due to no transfer of magnetic flux from the exciter coil

the key its self had to be inside the coil for it to work

still worth a try though.

cheers

Cant confirm or deny, but i have heard it stated b4 that the vdj79 motor runs thesame gearbox as a hdj79 and thats why it is detuned.
Getting a chipped vdj79's torque through the clutch may be the limiting factor

with the new 200 series the key can be outside the car and it will still start.

doesnt the 200 series have a start button though????as does the aurion

it is not the standard toyota transponder key set up

Getting the standard torque through the clutch is hard enough, especially when cold.

The clutches from new shudder like a bastard. Both the VDJ79 and the old HDJ79 did it too. I would have thought Toyota could have engineered that trait out of them by now.

And why didn't they widen the rear diff on the VDJ??

If you want to widen the rear diff, buy 105 rear discs/hubs, they are set 30mm wider each side. 105 front callipers have larger pistons...on same discs...bolting them on makes for better brakes...

105 front callipers have larger pistons...on same discs...bolting them on makes for better brakes...

Can anyone confirm this works? We have a troopy that is in desperate need of some better brakes.

The rear disk idea is a good one too if it works.

105 hubs are 5 stud.

I can't remember if the v8 70 is five or six stud???
