right im about to throw the 1uz into the mighty ln65 double (rusty roof)
originaly i was going to use a w58 out of a gen 1 surf instead of the standard g52
but ive just come across a r15#f
from what i know the r-serries are stronger than the w
but it has electric 4wd/2wd selection and a chain driven transfer
so far ive stripped the transfer apart and i was thinking about removing the electric motor (its just asking for trouble) and the centralising spring and setting up 2 detents and a small cover (like the 4wd mazda boys use to after the centerdiff lock packed up) and manualy opperate the 2wd/4wd selection
the truck has auto hubs so i could leave it in 2wd for daily drivng but as soon as i get to the track jump underneth and pull the shaft

not what i want to know is
is it worth using over a w58 and are the chain driven transfers reliable?
i have to make custom gearbox crossmember and driveshafts anyway so im not worried
i also have all 3 boxes available, i could even adapt the w58 transfer to the r box

any ideas?
thanks
jeremy

personally im considering a upgrade to a r series box .. so if you deside to go with the g or w series then i have a full setup for it ..clutch custom fly and bell + the modded clutch setup
otherwise if you go with r series... ill have your spear g and w box

for the 1uz ive got a custom flywheel that takes a heavy duty hilux 9.5" clutch, all from bnt

so how good are these chain drive transfers? it came out of a ln130 (i thought they were only in v6 and sheep shaggers)
i dont know if its a r150f or a r151f


and yes all the left over bits will be for sale-
1st gen 2L with g52 (goes well)
w58 with bell housing (noisy input bearing, i may replace it if it fetches a good price)- maybe missing transfer from a ln61 surf, still have the truck, most of its still there- missing front panels and doors no motor, short ln65 diff ect
all up for offers


what version 1uz are you running vvega?
does anyone know if the w58 and r15#f input shafts are the same?
thanks

nope different
and .. your better to get the 10" flywheel than the 9.5 my 9.5 was slipping with a organic now have a puck and its a it of a #### to drive i should have made a 10" and i should have made it more than 4.5 kg ... but it dose rev like a race car :d

could have made you a custom weighted 10" for about 550 bucks ready to sweet on a ring-gear
pritty sure that was molly too not steel
anything r151 is the same.. in the gearbox/input shaft .. they can have different transfer casings one straight though ..i.e chain driven .. and one dog leg... gear driven with a pto blanking

as for the chain drive... ive heard of them braking and its the main reason ive stuck with a g box
weve abused g and w series boxes in drift cars for years and never really had issues ... also in a uz powered rally car

but everything will break with abuse ... remeber these box's are 20 years old .. and have probably never even had a oil change ..so you cant ask to much from them

dont want the 2l but im interested n the g box.. pm me what your looking for

hope that helps

oh have the higher compression uz .. the one before the vvt ... that they put the bigger rods back into

I have been running a VF1A chain driven transfer case out of a LN130 for years with no troubles and have never heard of any trouble.

I have converted mine over to be air operated and dont have any problems. The electric motors give trouble.

I like the system and without stopping can change in or out of 4 wheel drive at any speed , even at 100kph as long as the front hubs are in.

Cheers Richard

could well be the motors stuffing out rather than the chain causing issues
this particular guy had a 350 chev

The other thing I like about the chain driven transfer case is the Ratio is 2.566 compared to the original transfer case which was 2.277 . That means I can still run 4.556 diffs which are stronger than the 4.8s

Cheers Richard

are 4.3's stronger again ?

vvega wrote:are 4.3's stronger again ?

4.5s are 9 teeth on the pinion and 41 on the crown
4.3s are 9 teeth on the pinion and 39 on the crown so the teeth on the crown are bigger making them stronger.
I think that is right from memory

Cheers Richard

4.3 is 10 and 43
only know because ive only just rebuilt one for a mate

yeeeeea...
ive allready got the heavy duty flywheel hilux clutch and uprated lux pressure plate, i was told it would be fine
just waiting on the bellhousing engine mounts and what gearbox im going to use then its goin in

so ill need to swap my clutch disk for one that will accept the r-15#f input shaft
the plan was to originaly use the w box

thanks

i twisted the center out of mine... well its cracked around all the retaining dogs
also ... consider a top diff mount... will stop you snapping leafs
also .. get a link storm g4 ... ill give you my map ... saves you about 1000 bucks of tuning and a pile of issues
i get phenminal fuel economy ... better than the 3y .. if you drive it liek a nana ....even then its still waayyyyy faster

just pm'd ya
im using standard crown ecu loom ect,
ive never driven a 3y vehicle.... never wanted to either lol
and for the top diff mount is that like a north south facing panhard rod?

Hi I know its a bit late now but you should have gone the auto gearbox varible ratio no clutch issues as for the 4.5 they are plenty strong enough as I use to run them with my lexus now run 4.88 for the last year hope that helps ps I also run with a crown computer dont need to use all those flash comps out there only need about 20 wires to run reel good L8R

yeap you dont have to run a link
but you will get .. more hp... way better fuel economy and corection factors for your tacho and speed input
in saying that the 40 40 40 ecu with loom is a 4 wire hookup and your running
and dont forget to run the main efi relay .. or your idle stepper motor wont reset

never liked autos, never will lol
cruz did you wire up your crown loom? ive got the 26 22 16 with an 8 on the side
anyone got a uzs131 crown wiring diagram? ive got the pinouts from lextreeme but my 22pin plug isnt from the crown and colours maybe diff
a link would be nice but saving $1500 plus tunning buys me a whole heap of fuel
im using a e36 m3 as a daily driver so ecconomys not goin to bother me
the plan was to run a after market relay to all the ign feeds and batt feeds to a fused source
i did that on a 4age r/t kp starlet- worked well

also got the crown auto trans and bell housing for sale, bolt on output flange type not the rubber doofer, 55,000 ks

so my w serries has a stronger transfer but the r15#f has a stronger box?
what should i use?
maybe time for a frankenstein tranny

thanks
jeremy

yea i did the wiring myself never done it before,as for fuel economy it does 20l a day in the bush so thats cheap,about 10l day at nationals.I dont have a stepper motor as I blanked it off.When I went to do the conversion HEAPS of people will tell you all sorts of things like IE:relays,o2 sensors,stepper motors are all needed its aload of crap I've got none of these and been running this set up for the past four years with no problems.As for wiring diagrams go to Lexetreme.com has all the wiring diagrams.PS I run the lexus auto on to a Landcruiser transfer case with a adaptor plate its totaly manual changing so if you put the gearstick in 3rd it will take off in 3rd so you cant stick it in drive as thats 3rd hope this helps if you need any more imfo or help just let me know.I use the same comp as you the 8 plug is the gearbox so you dont need to use that plug ,can dig out my wiring pin counts and what they do so it makes it easy to wire up like mine if you need help.where abouts are you in NZ L8R

I run the r151 gear box and the input shaft was the same as the w box. I started with the w box then changed after killing 3 of them. Thought stuff this and made a 10 mm adaptor plate to replace the w box plate and its a minter now plus i get pto to run the mans winch in the back. I run a 1uz with a m90 blower and 9lbs through a inter cooler and the gear box loves it still. This is in a ln65 dc hilux and y60 nissan diffs. Clutch is 9.5 inch pressure plate and we made a 5 paddle plate out of a old hilux plate.
I have found that i need a bit more slippage in the transmision and will be looking at fitting auto in there to slow me down a bit .

is yours in a road car ?... have you had to pass emissions for cert ?

cruz, yea id realy like the diagrams, ive got the ones off lextreeme, id like the type that has a diagram of the ecu saying pin one is possitoin 2 in top row 2nd plug red wire batt + feed, (found some for a 4age on club 4a) ect
did you ever run the steper motor? throw any faults?

i had my old e30 318 running m20b25 certed with out an emition test last year, is this a new thing?

and yes texlux is right r and w inputs are the same, maybe early g52 that uses the smaller inputshaft????
just spend this evening striping and inspecting the r box-all good

bnt quoted me a diff part number between ln61 w58 and ln65 g52

how did the standard ln65 diffs take the standard 1uz? spose it depends on driver abuse, ill start looking for safari diffs lol

depends on the engine .. or so the cert man tells me ... must pass a hydrocarbons test
mine pass's on that anyways
there is honestly nothing wrong with stock management at all ... i think i have a good setup engine wise and have tried both was and found the link better .. but ive probably only done about 20-30 efi engine conversions
ive even swapped around different efi systems of diffent engines.. i.e 4age onto 3sgte and 1jzge on a 2jzgte you woudl be surpeised what you can do if your willing to spend time doing calcs to make it all work
but TBH i did that to show it could be done .. not because it was the most ideal solution .. but they worked

as for input shaft ... keen ... i think ill r series box mine and be done with it all i need to change is bell housing .. the output flanges on the r series box is the same :d

as for the diffs
i think there fine for a uz ... but seriously look into longfields for the front ... advice i was given by some fulla's in the know
remeber uz's dont make "that" much power .

again i have a SHITPILE of experance with uz's but stuff all with 4wding

No its a national 4wd truck but I've seen the same wiring in a few road going cars,as for the test for cert dont know anything about it best u check with your certifer.Now if u go to lexextreme down load the wiring dia for crown & the ecu diagrams u can easly work out which wires u need mine are printed out and lanimated so I could take them out to the shed.OK now my first wiring loom had everything conected ie:stepper motor,oxy sensors and everything else I run this for about two years then did another loom I made now has none of those things and runs the same if not better.Everything u need to wire up your lexus is on Lexextreme as before ask heaps of questions as there are plenty of people that have done this conversion L8R

please dont get me wrong im not hassling your method at all .. done it myself and it works dam well
i have almost every uz ecu wiring diagram and im happy to supply and help anyways i can .... even have a tachometric relay for pump control
.. next step for me is vvt heads
man thats a sweet conversion

Hi ''no hassle'' just want to help a new lexus guy I know when I did mine LOTS of comments were u cant do it that way or no help at all so I went ahead with it anyway and some people HELPED heaps on Lextreme,I did get it going the only start up problem I had the first time I ever started was a couple of wires around the wrong after sitting there for awhile I went back and retraced it and it fired up straight away and idled.Its probaly the cheapest v8 injected motor around,now that I've had it for four years I wouldn't go back to carb & manuel gearbox and I want to help with new conversions.I'm considering super charging MAYBE got to get more imfo first L8R

hey there
just went over the diagrams i had (lextreeme) and yes there what i want lol
not sure why i overlooked them (probly the same reason why i forgot about the r15#f box laying in the shed lol)
cant wait to get it in and running!
just sorting out another cab and well side now

thanks guys
jeremy

mate of mine had done a couple of the vvt's on a link g4 ... and with a bit of work hes got over 300 @ the wheels ..n/a
has quads etc .. prolly not really practical ... but seriously the vvt heads flow more and btter than a highly ported set of non vvt heads ... if your gunna go s/c look out for some .. well worth the gains

eaton m90 for low down grunt.. or m112 of you want a bit more top end with a bit off loss down bottom ..... or a 671 or larger

will you go to aftermarket management if you do that >?

and tomo ... keep at it mate .... also if your looking to replace guards and bonnet .. i may know were there is a carbon fire set
not cheap .. but still choice

Quite often see supercharged 1UZs in 4WDs but very rarely turbos - why?

funny you say that ... mates doing one with a td07 :O on it .... i think the issue is toruqe gets you places and hp breaks everything

s/c you get lots of bottom end ... turbo will have you 500 hp + but your cv's and axels will just leave the truck
maybe twins would be ok to have a low spool

Yeah two small twins that have similar boost characteristics to a supercharger. I mean if you're only running 9-10lbs at the most you can set up so they just run out of puff high up in the rev range so you get more low down.

Most of all it's just cool to go wapish and get all the skanky bitches.

I'd love to put a 1UZ in my Blizzard, I've got a G52 sitting there which would work but I'm going to be running 38s so figured I'll flick it and try and pick up an R box.
