1fz-fe to 1HDT, Changed mind to FTE :)

[vSAHARAx]

Hey all

Just wondering if anybody has done this conversion??? Reason i ask is that i have a GXL 1HDT manual bolted to a 5sp, but the paint on mine is starting to show its age. Friends of ours has a 1fz-fe Sahara Auto and have offered it to me cheap. Sooooo for the price of getting mine resprayed for a couple more $$$ i could have an imaculate Sahara, but i do not want to give up the diesel!!!

Any help would be much appreciated.

as long as u swap tanks (the sub tank set up is different in the pettys), fuel lines(maybe), dash, and tailshafts then it wouldnt be too hard i guess?

[fester2au]

How old is the Sahara Troy. Don't forget there are changes to wiring loom and plugs etc and later dashes for example had different configuration on the circuit board etc. If it has the electronic auto isn't it integrated into the loom and ecu so keeping it manual would be easier. Don't forget the glow plug wiring probably isn't there and if it has cruise control they were different between petrol and autos.

I'd suggest it's a bigger job than first thought due to the small wiring differences between years and between petrol and auto. Otherwise the engine side should be pretty straight forward if you take your tanks and fuel system.

[killalux]

What about getting the sahara, Selling your truck complete, then with the sahara drop in the 1HD-FTE ? out of the 79 series for more power?? Or maybe a LS1 if ya not dead set on the diesel?

you could swap the 1HDT over, but i think it will be quite a bit invloved getting wiring to match up. Plus the cluster will have to be changed, fuel tanks, cointrol relays, list goes on

[vSAHARAx]

Its a post october 92, so has the 16" brakes etc.

Killa lux, what would i be looking at for the 1HD-FTE conversion???

It appears its going to be a bit harder then i first thought. Im unsure as to which auto box it has, whether it was the old type or the later semi electronic job.

Cheers fellas

If you decide to get the pety one and play with it, I would be interested in buying your old 1hdt one off you.
Cheers.

Hey mate, I haven't done one so not sure what you would be up for, Try PM mud4b, he has done one he could help out with all the little details if you went that way.

I beleive they bolt in pretty easy, and wiring shouldn't be too bad as long as you get the ute version, and use the 5 speed, not the auto. I beleive the tach is a problem to get to work, but nothing a bit of testing and research couldn't overcome

recently did my 100ser 1fz to 1hdfte
everything is different between the petrolauto and diesel models except the engine mts
all cruiser autos in the 1fz 80 on are electric control ie have there own computor
it can be done the tacho needs a sense wire run from the alternator then through a convertor which i know is available,but dont know where to get them from.
the rest is easy need to leave the 1fz auto computor and eng computor if you are leaving it auto reosonably easy to wire in
then the 79 putor talks to 1fz putor which talks to auto putor and all is good
have done 15thousand ks since the conversion and alls well

[Hamo]

leave it auto.
The 80 series auto is suprisingly very good of road

[doogie]

Hey v8zuki, did you do the conversion yourself, or did you get it done, if so do you have a contact no?

sorry, not trying to hijack the thread,.

thanks

[badger]

auto and manual chassis have cross members in a different spot.
Making the 1hdt work with the auto is not that easy. it depends on the year models as to how you can make the auto work as there is 3 different autos and about 6 different ways they are controlled depending on age and motor altho they all share the same name.

My Fte swap is also a petrol auto car and has about 20 months and 50k on it now without a glitch so it can be done.


v8 zuki i know a guy who does the conversions who can make your tacho work. the proper way.......... not off the alternator
also some 1fz's control the auto with the engine computer and some do it with a stand alone computer and some very early 1fz autos are fully mechanical just like a 3f and early diesel

Badger mate, you have just put your foot in it, haha, i too live in brizzy so will start drilling you for info .

Is your FTE out of a ute or 100 series? I bought the Sahara and picked it up the other night. its a 1fz bolted to a A442F box. It has to be Auto, im sick to death of toyota's crappy syncros and backlash. I want the 100 series FTE and auto.

Will sell my old 1hdt truck as soon as i have stolen alot of things off it

Keep the info coming fellas

Cheers Troy

[v8zuki]

my tacho is all good as the fte runs the same pulse as 1fz so all good
you have to run the pulsr off the alt for 80series models as they have a different pulsetacho
i fitted mine and hooked everything up and paid a gut to wire it took him 2 days to do it still havent done the ac yet but im slack at the moment
have to get a new hose made as i broke mine but as soon as its done it is finished
the motor in mine is out of a79ser ute so runs stand alone
love the economy and the power cant wait toget the piggyback power up module

I think he may have issues doing it the same way as yours. Because the 100 series 1FZFE runs quite a different engine management an transmission control system than the early 80 series, His may not work so easy.
My opinion would be use the 100series ECU, and wire up the immobiliser system aswell (harder to steal this way to). Also less things to wrong this way, as there is only one control module, and one immobiliser module.

I will have a look at my wiring manual tomorrow to make sure it is possible, but it should be. I ahve a holden factory immobiliser working in my cruiser no worries.

Hi i have done a few conversions of FTe's into 80 series
the petrol tacho will not run off the signal in an 80 series as it still runs a distributer and a hi signal tacho input
the 100 series petrol and TD both run a low voltage signal generated in the computer

defiantly get a 100 series donor car(for sure if you want auto) i have mated a ute engine to a ft auto before and it is not worth it
i have a 100 series engine and efi in my 80 converted it from auto to manual also have everything working ie immobiliser ,tacho and factory 100 series cruise
not supa easy for the electrics though i did mine all my self
goes great as well!!!! using very little fuel

Hey mate,

She will still have, twin Air-lockers, extended diff breathers, Marks part time kit, Genuine free-wheel hubs, bigger brakes on up front, factory flares off a 94 model cruiser (wider compared to early model flares), modified and high-flowed CT-26 Turbo charger, 3" Exhaust, decent sound system, Auto meter water temp, boost and pyro gauges, ARB air compressor. Big ends were replaced 23 000k's ago (just as a precaution) Injector pump was completely rebuilt about 12 000k's ago, Valve clearances and tappets adjusted about 1500kms ago.

Dont know what i will put on it, i suppose ill wait and see what others are going for on car sales and with the extras come up with a figure.


I plan on buying a complete wrecked 100 series dont care about the body condition, just want a minimum of motor, loom, auto gearbox. Im good with the mechanical side of things but auto electrics i will leave to a professional, or someone who knows what they are doing. Does any body know if the 5sp auto will fit into an 80???

Cheers

Jonathan what about this
"The petrol tacho is the one you need remove it from the cluster then all you have to do is change one of the resistors on the curcuit board from a 33k to a 20 k then it will work
it is one of the ones closest to the input for the signal if you follow the tracks it is quite easy to find
then fit it to your old cluster cutting the wire for the tacho at the plug(loom side)
make sure you connect nothing else to the wire from the computer or this will load it up and stop it working"

[v8zuki]

mine is auto and works fine
there is also the problem to overcome of the electric throttleand a cable
kickdown ????
mine is done but dont know if others are aware of it

[esp22]

whats the difference between the 100 series fte and the 79 ute fte??Why is it not worth putting an auto in a 79?Thanks

Hi fester i wish i could use a search button as well as you i can never find anything
yes that is the correct way and it works as thats what i do

i was responding to the quote that said "not to worry about the tacho it will work "as it does in the 100 series out of the box( not the case at all)

in the 80 series you must use a petrol tacho as a base and modify it
as i explained in the above text

cheers

jonathan

ps fester did you ever get your tacho going in the end?

[thrashlux]

whats the difference between the 100 series fte and the 79 ute fte??Why is it not worth putting an auto in a 79?Thanks

many differences between 100 series and 79 series engines more so in the management , turbo and pump

the 100 series is matched to the auto and the computer for the engine is intergrated with the ECT (electronic transmission control)

works much better as a package


main reason is 100s has buckets load more power potential due to higher fuel and boost cut settings that cannot be modded out with a chip etc

[vSAHARAx]

So thrashlux when are you moving back to Aus to do a 100 series FTE conversion for me

No worries and no I haven't got around to it yet, got the petrol tacho just haven't modified it yet.. Been in a quandry about whether I want to stick with the 80 so haven't done much to it. I was just concerned which part of your advise was correct in my case as I still had that PM and thought maybe it was wrong. Was hoping it was 100 series specific. Have now decided that I shoud keep the 80 so must get in and finish it all off. Had a momentry lapse of reason and was thinking of 2nd gen Range Rover (P38) but now decided that as cool as they are I can't toss the reliability of the 80 for something than can and often does break down without warning (as cheap as they are).

Got a drive in drive out cost, for a 100 series 1hd-fte conversion with a barrel intercooler and 3" exhaust, bolted to a 5sp auto....................................................... $20g



Bringing my old GXL up to scratch is starting to look like a nice idea!!!

[killalux]

How much of that cost is the engine or wrecked 100??

Nothing like reaching for the stars hey Troy. How about looking at little closer to earth with say a 79 series FTE and instal yourself. I know the engine in mine cost just under $8k from a wrecker with 6 months warranty and there is not that much wiring in use. Maybe research a bit more on mating it to the 80 auto or get another cheap manual box. I know auto would be sweet, that's what I'd prefer, but what do you want more a TD Sahara or a petrol auto. You've already got a manual TD now so why not one step up to a manual TD Sahara.

You'd want to do a LOT of k's and keep it for a VERY long time after sticking a $20k conversion in it and it'll never be worth the combined sum come resale unfortunately.

If you keep the GLX you should be able to get it painted fairly cheaply if you do the prep work, like under $1,500 for a professional job.

[midi73]

Hey I have read all of this with interest. This all seems to relate to auto and fte. How hard is it to put a 1HDT into a manuel petrol 80 gxl?
Cheers.
Oh and have you made up you mind on things yet vx sahara, I could still be interested in your old 80.
