Hilux 4x4 Forum

Soon as I get pricing from Lextreme or Harties we going to change the current 1UZ that unfortunately drowned two years in Scorpions Hilux.

Confirmed sizes of the 1Uz, 2UZ and 3UZ engines in physical size is the same. 2UZ just use a cast iron block so it can be heavier than the other 2.

So just pricing and availability and then patience needed now.

Lekker!

Will be good to see that truck back in action!

Gooi details op die tred oor wat daai 2UZ kos... Ek sal like van soo een in my 45 met die swaar blok...

Will be interesting to see the reasoning to choose between those 2 motors ..

Depending on quote

I also put in a order with lextreme for a 1uz, although they never priced on the 2UZ, the 3UZ was entry level 30K

So these are awesome motors if your budget permits

Ok just received the pricing;

1. 1UZ VVti
a. Wired for Manual gearbox = R16 000
b. Wired for Auto 4 = R16500

2. 3UZ VVTi
a. Wired for manual with 1 UZ Ecu = R25000
b. Wired for 5 speed Auto 1 UZ Ecu = R26500
c. Wired for manual with 3 UZ Ecu = R29 000
d. Wired for 6 speed tip tronic with pedal shift = R39500

Then the fearsome 2UZ Complete Engine wired up R40000, here comes the :alvarin: as they have to import if you want from the US another R40 000

Now it will be the 3UZ with its matching Ecu, with a few other extras, Cambelt changed, sparks changed, Powersteering reservoir and bracket with the matching 8 bar fuel pump. Just have to check the sump position.

Almost time.

A 2UZ out of the states will never have as little kms on the clock as the motors out of Japan.

So is the little extra kw and Nm from the 3UZ worth almost double the price of the 1UZ VVTi ...

Yip I agree Theo.

Was not my choice but to say we want the bit more torque that we can get. Still deciding.

Tend to agree with Theo very small difference between power and torque.

I did quite a study on the 1UZ VVTI. Have the cams cut to a 4x4 profiles and you will have more power and usable torque than a 3UZ.

Talk to Mastercams they cut the cams and do the heads . A 230deg @.050 duration with 0.406 lift is an ideal cut for a 4x4.

Just a quick questions on the cams being cut and head done. Would you still opt for the standard management or go another route?

Cant wait to see BosBeer back in action again!!

Standard management or what ever you use will not being affected by a cam change or cut. You will only move the power and torque curve up or down the rev range.

Keep in mind the Lexus V8 was designed being used in cars. Vehicle weight and gear ratios plays a vital roll in cam shaft design and profiles.

One of the main drawbacks of the Lexus v8 is that you have a very few aftermarket options available. Modifying a Lexus can give your pocket a very hard knock.

Bit more progress so far.

We decided to go with the 3UZ, its getting prepped as we speak. We keep it std, run it off the OE Ecu to make things simple. Once the engine is in one can look at other things. The Bakkie is standing now for a while so we better start soon.

Over the weekend the old motor will be stripped out, one have to check what the real differences is if the 2 stand next to each other.

This time a better air intake system will be in place.

Hi Louis!
I like your decision!
I am busy with the same conversion. But I don't get enough time to do everything myself!
So please keep good notes of everything you are doing, as I may bring mine for you to do as well.

Ek sal notas maak met fotos soos ek aangaan. Moet nogals se ek sien nogals uit daarna. Dis maar 'n storie op sy eie. Daar is al baie dingetjies wat al op die bakkie verbeter is die afgelope tyd.

Net voordat die 1UZ sy dinges gesien het was dit 'n plesier om te ry. Oooi, daai grom van die V8.

Dis sal nou 'n ander ding gewees het as die 1UR beskikbaar was....

Louis... how about dual snorkels! That would solve the problem and supply heaps of fresh air!

Subscribed - been waiting for a lekker thread for a while !

Pm my.

Ok some time lapses. I collected the 3UZ and offloaded the thing. Its 190kg in weight.

But it idles smooth!!!

Its in fact just a 1Uz, very similar. One thing is that the power steering pump reservoir is now separate and on the 1UZ it was on top of the power steering pump. At the moment I still stripping all clean in the engine bay that we start fresh. Old engine already out.

O Yes, I have to take the old petrol pedal assembly out. The rebuilt the new pedal in, no more cable as we used too.

A new airbox in shape will be sourced or build. Ecu will be built into a waterproof box that I place into the engine bay. Well we still.

Any update Louis?

Roelof sort of. Engine is ready to go into the bakkie again except I am waiting for the poly bushes for the engine mounts. The Ecu still need to be built into a waterproof box that have to get a space in the engine compartment.

Thanks Louis. Keep us posted.
I will come to visit you in October. :-)

Been a while since I posted here. Well Received the new bushes. Timeously placed into position.

Before I started the final placement of the Engine I phone Johann to ask if he will mind if I could cut the front top part off where the bonnet latches. Reason was I wanted so see more clearly how to place the 3UZ. He said it will be ok, he use this Hilux only as a Toy. I assured him I would make the front latch part work again with good place support brackets that will keep things in place again.

With that out of the way I made the cut, then lifted the Big 3UZ into position. One have to be careful not to bump things like the oil filter on the one side and on the other the power steering pump. As I was lowering I realised I would to disconnect the steering rod to steering box. This would make it easier to lower the engine more precise.

To be honest I was more worried of bumping things I did not look at the time. Well just after 3pm on a Sunday it was perfectly in. All Bolts in position as fastened.

I looked and saw 2 points you guys can look at too. This is very wide engine. The oil filter wont fit on the passenger side, well to say the normal one that comes with it. Ok this is the easy part. Go buy a Z87 oil filter, it wider but shorter, this will sort the space needed.

Not so easy is with the current configuration I cant move the engine & gearbox more to the front or to the back. I wont tilt the engine either. The power steering pump pipe is 1 mm from the steering box on the chassis. Eish

Well consider all I will have to see what I work out there... I got something in mind but want to test it 1st.

Die Mounts was wat in was. Is nogals goed gemaak. Al wat gedoen het is om die regte size poly bushes te kry wat op groote reg pas.

Gister aand net vinnig af geneem. Ek sal bietjie dit meet. Die plaat is 5mm dik.

Dankie Louis, dit help baie!

Ja nee wragtag. Help as ander manne ook besig is daarmee.

Hoe moeilik is dit om so stel the laat opmaak?

Ek sien jou engine het nog sy hydro pomp in. Gaan jy hom gebruik vir die visco fan of gaan jy hom uithaal?

LouisZ wrote:Die Mounts was wat in was. Is nogals goed gemaak. Al wat gedoen het is om die regte size poly bushes te kry wat op groote reg pas.

Watse size poly bushes het n ou nodig??

Die Bushes was die vir die L/C bakkies se bladvere. Omdat die mounts klaar gemaak klaar in gebruik was en goed gemaak is was die die naaste bushes wat sou pas. Ek stel voor oorweeg die IFS Hilux se bushes, makliker om te kry.

Ek gaan die pomp gebruik Reinhard.

Dankie vir die info.

Waarvoor gaan jy die pomp gebruik? Myne het nog sy pomp in, maar is gesê om hom uit te haal as gevolg van hy nie gebruik gaan word nie.

Ek hou hom op standby as die elektriese fan nie oordentlik koud maak. Dan die viscous opsit met die platter Mercedes fan.

Maar hou vas, as jy nou daai pomp in los, hoe gaan jy keer dat hy nie droog loop en skade kry nie? Klink my dis een rede dat hulle hom uithaal.

Hoekom se hulle mens kan hom uithaal?

As die belt roete so lyk oorspronklik soos in die foto en jy hou daarby sal dit werk. Hoe gaan die belt roete lyk as hy uitgehaal is en watter belt gaan jy gebruik?

Het jou engin nie ene?

Askies, ek moes dalk beter verduidelik het.

Daar is n weergawe van hierdie 3uz wat sonder die hydro pomp gekom het. LS430, hy word deur Toyota Suid Afrika support wat parte aan betref.

Ek het self die fan belt by toyota gaan bestel, en op die engine diagram vir die LS430 kon mens duidelik sien die Hydro pomp was nie daar nie, i.e. die belt is korter.

Moet in die week die parte gaan optel by toyota, thermostat, waterpomp, timing belt met idler en tensioner, fan belt ens, wag net vir die ATF vir die ratkas, klink my uiters belangrik dat die olie vervang word met die toyota produk. Sal dan foto en part nommer van die fan belt opsit.

Wat die hydropomp self aanbetref, soos ek verstaan hy het net 2 boute aan die voor kant wat hom aan die blok vas hou, as jy hulle uit haal trêk die pomp net so uit...

Dis interresant.

Post 'n foto van voor af van die 3UZ wat jy het. Nou nuuskurig.

Hoorie, sal vanaand gou n foto neem, is mal besig by die werk.

Maar, ek moet noem, ek was in my tjops in verkeerd... Het met my tuner gaan praat, daai outjie wat ek aangedui het met die rooi pyl, hy sê daai is net n idler, nie die hydro pomp nie.

Raai wie is nou lekker confused!!

Post die foto later. Sal maar koppe bymekaar sit.

Sovêr, compression toets op al die cylinders gedoen, en olie druk toets net om te kyk sat als reg is, T belt en tensioner vervang, fan belts ens.

Geen hydrolic pomp op die 3uz nie, so ek glo nie jy gaan enige issues hê nie. Dalk net die olie filter wat te lank is, en teen die chassis kan skuur. Gaan vanaand gou daai outjie insak en kyk wat maak hy.

Hoe vorder jy met jou projek? Ek en knuppel stoei en roei aan, maar 3 koppe is beter as 2

Hoorie, as jou enjin op plek is, hoe het jy hom ingekry met die manifolds aan, ek hoor mens kan sukkel om hom gepas te kry.

Ek kom draai oor die naweek by my skoon ouers in Secunda. Miskien kom inloer.

Jinne ASB!! Al is dit net vir 5 min en n handskut...

Enige rede om raad te gee

Sal jou my nommer PM of hoe gemaak?

Hierdie is die prop wat gebruik word agter toe. Dis sonder die centre bearing. Let die double guardian joint.

Lyk baie goed!

Louis, as ek mag vra, hoekom het jy die center bearing uitgehaal?

So lank laas iets gepost hier. Wel die 3UZ is in, reg geskuif. Outlet manifolds klaar en die Stuurboks heeltemal vorentoe geskuif om die powersteering pomp spasie te gee.

Die reen maak dit moeilik die week maar laaste ding is die engine loop en vrek, blykbaar die transponder keyring met die sensor. Sal more iemand stuur dat daar gekyk kan word by Lextreme.

Klink onaards as die ding so kort grom gee. As dit nie reen die naweek en die transponder problem is opgelos ry hy die naweek.

Die fotos sal volg oor die naweek.

Nogals vordering sover oor die naweek.

Die 3UZ het gebrul oor die naweek.

Harnas is oorgedoen om by die Ecu te pas, Ecu security pass is ook weer gedoen.

Nou allesnetjies maak die week wat kom.

Vordering op Bosbeer.

35 duim bande is op. Engin loop mooi.

Vrydag so 7 km gery. Die 3UZ hardloop met die 5 spoed ratkas bitter vining deur 1st,2de en 3de, dan is mens klaar by 100km/h verby.

Vandag deurgevat na 4x4 Direct Centurion dat ek kan sien of ek 'n Snorkel op hom kan kry.

Hier so foto van die engin

Dit lyk uitstekend Louis. Wel gedaan.

Ok, I used the Prado 120 Snorkel for this one.

Airflow allowed because the Prado's snorkel is nice and wide and also piping is 76mm from the snorkel to the air box, not the 52mm piping of the OE 4Y. Also you have piping only make 2 120 degree turns. No long pipes and lots of turns.

Picking up a on pipe I saw once at a scrapyard tomorrow morning for in between the snorkel and air box.

To mention, Difference in power shifted from the old 1UZ 3.9lt to the 3UZ 4.3lt

1UZ had more lower down torque at about 1100rpm's, the 3 UZ REaaallly scares you from 1700rpm, then things get rough very fast from 3500rpm's.

The 35 inch tyres don't exist for the engine. A slight pull away from 1st and foot down changing from 1st to 2nd then 3rd is very quick if you still floor it you get to 100km/h fast. Remember its 5 speed OE 4Y Manual gearbox, not Auto.

Most of all the sound the V8 makes is refined, but still bloody nice.
