1KZTE into Bundera

jj1959 · Post by **jj1959** » Sun Mar 20, 2011 8:50 am

I have aquired a 1kzte & auto trans out of a kzn185 surf. I am planning to put the motor & hopefully trans into my Bundera. Has anyone grafted the split case transfer case on to the back of the A343H trans that is in the kzn185 or should I be looking at another way?

Get a transfercase and the tail section of the auto from a one of the early 3L or 2.4 Prado's

The autos are all from the A340 family and should all bolt up.

If thats the case I might as well use the entire trans from an early prado & just change the bellhousing.

True.....Sort of....
If you get the 2.4 2LTE then yes.
If you get the 3.0 1KZTE...then you have solved your problem...

Dont forget the ECU! It controls the engine and Auto..

I have a 3.0 1KZTE in my square Prado...

Is your truck imported from Auz? a real Bundera or is it a LJ71 Prado?

jj1959 · Post by **jj1959** » Sun Mar 20, 2011 1:37 pm

It's an early pre Prado LJ71 Bundera with 2LT motor & R series box. My other option is to source a solid mass flywheel & clutch. I'm getting rid of the ecu & putting the fuel pump out of my 2lt in it. If I stick with auto trans I'm going to have to manually switch gears. Has anyone done this?

Mine is badged as a Prado, don't forget pics

Yes people have done manual controls for the auto.
Most do it when they swap in the 1UZFE and auto...
I am sure someone can suggest who to goto..

"84- "87? was pre Prado. The trailing arms are different, so is the shock setup

What's the model number of the bundera?

I know this isn't going to help, but I've found two types of transfer cases on the auto boxes (not counting that wierd KZ one that drops on the wrong side) I've had the parts boy at toyota conferm differance in internal parts... unfortunaly I didn't get a chance to measure up input shafts etc and just to make it more difficult the cases look identical, the only reason I know the diff is the guy who I sold it to is a mechanic he picked it up when he tried to swop parts to make one good one
As for manual"ising the trans its been done alot in the states, you can buy plug in computers... and I was planing on doing this to my next project after I've got it going
As for the standard comp for the auto... I don't know how that will go as its in the engine ecu, I know the engine will go into limp mod if there is no feed from the comp... makes me wonder if it works the same was for the trans, you could look at fitting a stand alone trans comp out of a surf

If your interested, clive might have mentioned I've got an auto transfer case apart on the bench at the moment, I only want the low box out of it, so I could put it back together for you and swop you for the KX one... if it fits :roll:

As for pics dead easy post them up on a site like Photobucket.com and then copy the link and post in between the "img" tags

A 185 Auto needs a 185 transfer case for it to work. The 130 transfer case (drivers side drop) bolts up to the 185 auto but the splined shaft is too short so to put a 130 transfer case behind a 185 1KZ you need the 130 auto as well.

We know this from a friend who did a beam conversion to a 185.

Re Reece's comments

You can use the trans computer out of a Jeep Cherokee for the A343 Auto, worked great on mine and was only $80 from a jeep wrecker.

If the auto part of the Engine ECU doesn't go, you will need to use the lever and you will get:

1 - 2nd
2 - 3rd
3 - overdrive

You will loose 3rd gear. Or at least the A343 in my Prado did without a comp.

Cheers for that NJV6 looks like I don't need to put mine back together
anyone know about the Asin 30-80 out of the Isuzu Mu, it was longer in the housing part of the transfercase.... bolt pattern looked to be the same

hey WJW did you replace the electronic selector on the side of the case with the ecu.... just I remember them being different with the different vehicles they've come out of :roll:

again not something I ever thought to pay attention to
Just cuirous as I've got a trans here that I was planing on useing (60% certain its come out of a YN130) but no loom or comp... been keeping my eye out for surf computer... as this is a fair bit down the project list I havn't done much research yet anyone know if there is any differance on the computer maps for the diesel vs petrol or was the differance managed with different torque converters.... hmm might be time to start doing some research

Sorry for the hi jack JJ

Cheers Reece

There are literally hundreds of variants of the Aisin trans, In Jeeps they are AW4's in Toyota A34x etc.

The ecu's for both the A343F (Prado) and the a343H (Surf) are pretty much the same, its the transfer case 4wd selection and output shaft offsets that are different. Not sure if you could bolt up a surf TC to a Prado auto though.

You can use a Jeep AW4 ECU to control the auto, from memory there are two versions, I could only get a mark 1, but the mark 2 gives better fuel economy.

jj1959 · Post by **jj1959** » Mon Mar 21, 2011 7:08 pm

Cheers. Back on subject. I'll come and look at what you have got sometime Reece, but it is looking more like I may have to find myself a cheap flywheel from somewhere & just use my manual box as I also have a pto whinch to contend with as well.

De-Ranged · Post by **De-Ranged** » Mon Mar 21, 2011 7:31 pm

I'll be down CHCH later this week for work, other than that any time
BNT do a solid flywheel conversion for the 1KZ I've fitted a couple of them now, last pricing they were the best

I'm planing on running a pto winch off the auto... don't know yet if this is going to be a good idea but I've got it sitting there so might as well give it a try, if it fails :lol:

I'll convert the pto to a cheap version of hydrolic

Cheers Reece

jj1959 · Post by **jj1959** » Mon Mar 21, 2011 8:12 pm

It works. You just have to control the pto running on with the torque converter., so you need to lock the trans before engaging & disengaging the pto.

wjw · Post by **wjw** » Mon Mar 21, 2011 9:08 pm

can't you just get a prado transfer & auto and use the standard toyota PTO bits?

jj1959 · Post by **jj1959** » Mon Mar 21, 2011 10:12 pm

Yes I could. I got the kzn trans for nix with the motor so was hoping to graft on the LJ71 transfer case to save cash. But its starting to look to hard. Trying to come up with cheap easy options but as we all know nothings cheap when building a truck.

I'm currently investigating a manual fuel pump conversion for my 1kz-te
My research currently says that it is not quite as simple as just bolting up a 2lt pump and winding up the fuel .

Apparently you need a modded 2lt-e pump body, a landcrusher pump top / boost compensator and modified 1kz pump internals.
Then some one with the nouse and tools / workshop to set it up properly so you don't proceed to melt the pistons .

I'm budgeting around the 2k mark to properly and reliably do this mod

jj1959 · Post by **jj1959** » Tue Mar 22, 2011 6:48 am

You are correct. You can't just bolt them in & wind up the fuel. There is afew other adjustments you have to make. I've got a friendly Diesel mechanic thats done a few of them now so I will just hand my pump to him.

Already have the pto & winch. Just trying to do the engine conversion now.

jj1959 · Post by **jj1959** » Thu Apr 14, 2011 10:43 pm

Has anyone got a tailshaft adaptor for a KZJ78 auto trans lying around that they might want to get rid of?

I'll check if Ricks going to use the one from mine.
