holden v6 into lj78 prado now 1uz-fe feeeeee88888888

[haynzy]

After many thoughts of leasing/buying a new truck for work I cant get past the fact that every aspect of my prado suits its purpose aside from the lack of power and mounting compliance costs of running a diesel,
question is, whats the easiest way to dump a vr v6 in place of the ole 2.4
Would prefer to keep toyota auto to keep the centre console original but can live with it changed.
I will be paying someone to do this one so the quicker it can be done the cheaper it will be for me as I need it for work.
So all you gurus fire away!!

[rokhound]

I would have thought the marks adaptor and pre built loom would be the go wouldn't it? Then it almost becomes an engine swap as opposed to a repower.
I have a light truck (makes it into WOF std by 50kg) which is diesel and I am thinking about doing the same thing.

[namtaf1]

go with the marks kit i got 1 in my prado but its a manual goes real good and looks tidy to.

[gimmemud]

You wont get a kit that will use the Toyota auto, they haven't made any adaptors that'll do it. You could just get an auto motor and get the transfer case adaptor which I think will be a different transfer required though? Dunno about others but if you go with marks they pretty much make everything for the swap like rok said, even little things like tacho interfaces so it all looks factory still.
If you email marks and tell them what you want to do they will be able to tell you everything you need, they've always been real helpful whenever I needed stuff.

Fairly sure you can use a bighorn 3.2 v6 bellhousing. The bellhousing pattern on the motor end is the same as the holden v6 and the gearbox end is the same as the toyota auto (well because a bighorn auto IS a toyota auto).

Id just get either the whole bighorn auto to change parts over or grab the bellhousing, oil pump and input shaft (only a couple of bolts and it slides out) and the torque converter.

But why you bothering with a v6, you know you want an 8

the lexus idea is getting more attractive now

[Jerry]

What about an intercooled 1kzte?

[smurf182]

What about an intercooled 1kzte?

I guarentee the answer will be

Cost

Try picking up a 1KZ for the same price as a UZ or ecotec donk, not gonna happen.

[haynzy]

What about an intercooled 1kzte?

cost of engine will be more than the cost of whole engine swap almost,
plus if you read my thread Iwas trying to get away from the mounting compliance costs of running an oil burner

[Jerry]

sorry didnt read that bit ..... drop a lexus in it, theres a few recent threads here on bolting the a343f up to the 1uz....

[haynzy]

so i found that I can get a bell housing to mate the holden v6 to my prado trans , now question is will a link or similar ecu control both the engine and transmission?

[skid]

STOP what you are doing

get in touch with Pedro, hes just slapped a lexus V8 into an auto prado for a mate

it may be easier than you think

[turoa]

so i found that I can get a bell housing to mate the holden v6 to my a440f, now question is will a link or similar ecu control both the engine and transmission?

Are you sure its an a440f? I thought prado's ran the A340x series? and cruisers ran the 440's

I think you will be hard pressed to get an engine ecu to run the trans, you will probs have to run the standard diesel trans computer or change it to a surf v6 trans computer (if they are standalone??) or go manual shift

[Jerry]

Should be a A34something ...... similar to the Surf/Prado, the Prado's have the Cruiser transer cases on them.

still to expensive which ever way you look at it, way to labour intensive considering I am paying for it to be done and need it done fast,
commy ecotec bolted to trans through specific bell housing, little bit of fiddling with flexplate some basic engine mounts then its just the basics.
lexus means splitting both autos to extract bits needed changing engine and tranny mounts, drive shaft lengths change and still the same elec probs.
In short already thort of this cause 8 is better than 6 but for what I want its just not practical.

it may be easier than you think, from what I heard, it pretty much fell in the hole. I may be wrong, but then again I could be correct

but you seem to have your mind set on the 6 so forget I spoke

auto mods, 30 mins

tranny mount unchanged, grind engine mounts off and relocate

drive shafts stay put

need to wire lexus up, i now believe it possible to run std auto confuser, need to connect into TPS on lexus, (easy) or make it manual shift, also relatively easy

radiator std ok, get hyd fan mount to radiator and run of lexus oil pump,
mod sump, get front sump motor,

motor fits with about 10mm clearance from fire wall,

easy when you say it quick, probably a whole lot less mucking around than shoving a commodore in,

have just read the pm pedro sent me a while ago may have to re think

[Madaz]

If you dont mind manually shifting the trans, you can just use the standard prado box straight behind the lexus,
The only thing i did to mine was use the lexus torque converter.
Havnt had any issues with it at all

Cheers

Thats how it works eh? Just when you have a plan carefully thought out to the nth degree some clever bugger says "did you consider this..." and the whole plan turns to custard or heads in a different direction.

just need to read the info in the first place

[haynzy]

right so we gonna do the v8 thing now what i need is some guidence on the wiring side of things engine and trans

[Jerry]

if its any help I've got a Lexus U1 bellhousing with a R15x adaptor plate sitting here, you would need to find a R151-154 Prado manual box but might save you the hassle of wiring up an auto.

Also have you checked out rather than do a conversion would be to sell your 2L-Te LJ78 and find a 1KZ-Te one ....you may find the cost difference cheaper than the conversion....

do you ever read these threads before you post jerry!! dont want diesel and want to keep interior of truck as standard as possible hence why im not simlpy adapting the transfer case to the th700 holden trans

[Pedro]

www.lextreme.com your friend, if you intend to wire yourself, there are wiring diagrams for most lexus confusers,
http://www.lextreme.com/misc.html

or get hold of vvega in Hamilton, he could possibly get a uncut harness off you and modify it so you have put power in here and do a few connections to make it run, as for the auto side of thing search the hell out of the web to find wiring diagram for the auto, or try toyota, go see a mechanic with some beer under one arm and ask nicely, they may give you a copy of the relevant diagram.

cheers

If you get a 1UZFE with auto box, loom and ECU..(uncut)
You are all good.
Just swap the output housing over from your old auto to fit on the new auto and transfercase will fit.

Heaps of info on the net, the auto only uses 3 wires to control the solenoids. Although some have 4 the extra one controls line pressure.

I made a breakout box years ago as a bit of a play around. Took control of the auto, and use paddles if wanted, but the curcuit would reset itself and go back to 1st every now and again.
Damn chips

The 1UZFE is the easiest swap to do for the square Prados, but the V6 Toyota is an option also as they use the same auto.

When my 1KZTE snuffs it, I will be in the same boat as you. I like my diesel for the torque and water resistance.
But love the sound of a V8....

Cant just cut the output shaft down and bolt it to the transfer on prados. Pedro found this out the hard way, apparently they share fluid or something. I had thought it was the same as surf where you can just unbolt and bolt.

Its easier to swap the bellhousing, oil pump and input shaft (make sure you do this as the 2lte input shhaft is too long for the 1uz) but it only takes about 10 mins as its a very simple bolt/unbolt.

There is an extra speed sensor in the front of the gearbox that is not used on the prado boxes. The boss is there and can be drilled out very easily and the hole for the bolt is already tapped. I did it on my auto, but im unsure if you actually need it or not?

Lexus auto = 4 solenoids
prado auto = 3

All you need to do is a little bit of mix and match with wiring and it should work sweet as.

[kbushnz]

Yes that's what I heard also.
There are long and short output shafts on the auto's.
You can swap them over, just need to pull down the autos.
The auto and transfercase don't share fluids, however the tail shaft extension / adaptor which mates the auto to the transfercase does.

There is a seal in the adaptor which stops trans fluid getting into the transfer case and vice versa.

there is a oil port supplied by the auto (prado) that the lexus auto does not have, this lubes a bearing in the adapter, and is you don't run it apparently it will just seize up on ya , i had a look then went for swopping the front bit around
much quicker

[kbushnz]

Ahhhh thats good to know.! (for my future engine swap?)

Can it be drilled out?
