1KZ-T powered LJ70 Bundera?? (looking to convert)

[lostcause]

I am looking at fitting a 1Kz out of a Surf (front-cut) into my 1986 Bundera.
1.) Is the stock R151 gearbox bolt pattern the same as the 1Kz-T?
2.) Has anyone done this conversion or mated up a R151 to !kz-t which originaly had the auto box behind it?

Thanks for looking, great site!!

I'd keep the auto.

[lostcause]

I pulled the 2lt out yesterday and picked the 1KZ up last night, given it a quick clean. I am going to try swapping to the R151 before venturing down the auto route, or should i say get my hands on a bellhousing to suit.
What i have read on other threads so far is: (but nothing is first hand of course...)
1.The 1kz came factory with the R151 in some surfs 94'
2.the auto computer can be used still with the R151 with a return or loop wire, (guess for it to start as if it were in park?)
3.using the R151 would eliminate fair bit of the ecu to auto box wiring making wiring it up a little easier (which i am not intending on doing anyways.)
4. the output shaft is to short on the R151 to mate up to the 1Kz
5. some prados use the 1kz-te/ R151 combination. (unsure if this is the latest generation of the 1KZ in the prado?)

i am leaning toward the manual so that i dont need to fiddle with the transfer case etc, surely economy would be a little bette tor?
The R151 is in good nik and transfer had work done to it before i bought the bundy.

can anyone add too this or confirm any of the above?
i will document my progress and findings for anyone else thinking about the same conversion.
Cheers

What motor do you have? 1KZ-T or 1KZ-TE?? One is EFI and the other isn't.

[lostcause]

my bad, i have the 1kz-te out of a 94' surf.
Yesterday i rang around with no joy, CRS and snake both do not offer a bellhousing or adaptor plate to suit.
I have emailed marks adaptors and have a friend at toyota doing a bit of research on a new bellhousing, also have found a manual 3.0l prado being wrecked so will go look at its bellhousing for compatability.

The 90 series Prado and previous model Hilux used the R151F behind 1KZ-TE, the 120 Prado uses R150F from memory.

You should have ordered a KZJ7X manual front cut to go in a bundera. Only minor fabricatrion needed as it would come complete with gearbox and transfer.

[lostcause]

but i didnt and bought what i could on a budget... with the correct bellhousing the conversion doesnt look too complex, engine mounts appear to have to move forward a few inchs at the most.

[Turbotojo]

As long as as you have all the wiring it should be good. I was thinking of getting 1 KZ but a 5L is an easier fit for me but not as smooth and torquey.

[lostcause]

after 32 calls, 3 forums and 5 emails i have found a bellhousing and should be in the mail tomorrow... fingers crossed its corect when it turns up. The bellhousings are available new for $695.00 from toyota, $250.00 from wrecker.
next question:

has anyone had much to do with constant weight flywheel conversion for 1KZ?? is there a kit avaiable or do i have to source bits individualy. Will try exedy tomorrow as a starting point.

[Viper]

Mate! Best of luck. I know what you mean when you do lots of research and it all comes together... and you get a bargain out of it.
Interesting project. Look forward to more installments (and pics)

[lostcause]

managed to order a constant flywheel conversion kit/ clutch etc from pbr- $850-

not bad considering a dual mass flywheel alone they want $1020-
hope this all goes together.

[lostcause]

all my bits are here and on fittment of flywheel have noticed a few things:

1.)Constant-mass flywheel conversion kit doesnt some with spigot bearing- no prob
2.) auto flywheel attach bolts are not long enough for constant-mass flywheel- just so happens that they are a toyota queer size- so yip waiting for bolts from toyota!

so project on hold for yet another week.

[Bundy]

Good to hear its falling into place for you mate.

Just a quick Q what have you spent thus far on the conversion so I can compare to my 1UZ conversion

[lostcause]

cheers bundy, so far the pricing is as follows:

1kz-te= $2400 (motor, loom, p/s, a/c, comp etc.)
R151f to 1KZ-TE bellhousing= $250
Constant mass flywheel/ hd clutch kit= $850
New Radiator=$375
Flywheel bolts= $45
engine mounts= $50

so far $3970-

still got a nasty electrical bill coming and exhaust system, i also had the R151 in the vehical as std.

is it compareable? I was keen on doing a 1uz conversion..... but old man talked me into another diesel, also it should be a tad more economical in the long run!

i have been taking heaps of photos and will post em as soon as i work out how to shrink them, also all part numbers etc for anyone else toying with the idea of a 1KZ swop-

it really has not been too big a job thus far, the waiting game for parts is what takes the time! picked up my last two flywheel bolts this morning which had to be ordered from japan as there were only 6 available in Aus.... go figure. So tomorrows job is out with the donk, Torque up flywheel etc, paint out the engine bay and bolt the 1 KZ back in. Hoping to have it to an electrician by mid week. :D

[lostcause]

Few Q's:

1.)does anyone have torque values for flywheel/ clutch assembly on hand?
2.) info regarding tricking an auto computer as i have a manual behind it.
3.) Pin outs for a 1kz-te 1994 computer

any info would be much appreciated, cheers

[lostcause]

Still after the pin outs for a/t ecu if anyone can assist-

Just waiting an a radiator and my 1kz-te 5speed bundy is ready to be trailered to auto elec over the weekend!
thanks

g'day, it sounds like youve done a fair bit of work and spent a bit money and i dont want to burst your bubble or anything like that. but what iv heard about the diesels in the Surfs is that alot of them will do head gaskets and they do it often.

[lostcause]

myth, keep em cool, serviced and they are as reliable as. besides its the 2lt surf that has a bad reputation for head nasties, owned both and its like chalk and cheese!

well then i stand corrected

[lostcause]

been a few months, happy to report my 1kz bundy has a little under 15000 km on it and hasent missed a beat! economy is good, better than my ol auto 1kz anyways!

Damn, you got out of it a lot cheaper than i did!!!! I ended up clocking up close to $10K to do my conversion in the lux, but that included a lot of other crap too.

Any issues with heat yet? ive found mine gets warm running the stock surf radiator and fan. Ive got a 10 blade fan off a aussie spec 1KZ and im going to shoehorn the aussie spec alloy radiator in there too to see if that makes a difference. Was only an issue on hot days on hills pushing hard though.

[Turbotojo]

What's the fuel economy like? A mate of mine gets about 13l/100km out of his KZJ95and it's in top condition. Bit much if you ask me. I'm down to about 11.8l/100kms with my 2L-TE. But it's still better than a petrol V-motor swap.

[lostcause]

good day, sorry for the late reply-

im getting around 660km per 70l tank for general driving city and highway wich is good compared to my last 1kz wich was auto... lucky to have got 500km per tank.

[lostcause]

i havent had any heat issues as yet! put a new radiator in the bundy when i did the conversion, i installed the biggest 4 core i could and retained the engine driven fan, no thermos.
In my last 1kz surf i had endless temp problems when towing or on the soft stuff at snails pace. not enough airflow with a condensor, gearbox cooler and spotlights mounted up front maybe??
