95 sierra V6 and Lux Diffs

[V.W.Dave]

I only post on here beause i thought it was the pinacle of 4x4 tech , clearly i was wrong , there is some good advice however seems more bitches than anything.

I think clearly you are missing the fact that you are not the first person that has invented this wheel. We (most of us) are just leting you know the $#!t fight you are about to jump into can be done, has been done and it will work but in the guidlines you gave it will not work.

Something that has taken me over a year to figure out about this sight is understand what people are telling you don't read them as they are having a go at you. There are some VERY smart people on this site (gman, BlowJoe, Blackbull to just name a few) these guys have built some of the most capable daily drivers on the road. It is not always easy to find the good advise in between some of the BS you find on here.

If you do a search on this very subject you will find atleast 20 threads over the past 12 month all asking the same questions you are now. What has supprised me thus far is that every bit of info you have gotten so far is actual tech advise and it is all fairly good info. So far every one is telling you the exact same thing go ahead and do it but it is not going to turn out the way you are thinking it will.

It is very strange that you have not had 5 or so people jump on here and tell you that your an idiot for doing it and blahh bllahhh blahhh don't do it.

No one so far has really said anything wrong but it is turning to that very quickly. If you think you have enough info to get your self going then stop commenting and start building. Make a build thread prove us wrong do it your way thats the beauty of it being your build.

Some of the best advise I was given on this sight was shut up and search for the answer its all here and its all already been asked. That way you don't have the answers directed at you but you will get your answers.

WOW its not often I am nice and not trying to stir up fights......

As for the alloytech well first marks adaptor dont have any adaptor in stock to mate it to Lux Xfer
the Vz wich came with the alloyteh run a body control module wich makes life a whole lot harder as i would then need to run 2 aftermarket computers one for the motor to eliminate the BCM and one to take care of the box , buy using a alloytech i make more work than the gains outway .

alloytecs came out with the 4l60e aswell

Yes but aording to marks there is a slight difference and they dont have any adaptors in stock to suit

You are right hence why i now have a complete VS ready to strip
A st of Lux diffs with gear driven Xfer case , a high steer kit to suit an ifs lux s/box and a few other little bits on there way , i intend to gather a many parts as i can before i pull the car apart , and as i work away for months at a time it will be awhile before i can actualy start the build hence the gathering of parts now.

One question is if i run Lux springs wich seems to be a good idea am i better getting brand new ones set to the hight i want or removing a leaf as they are designed for a much heavier vehicle , well the rear will be atleast the v6 will change the front dramaticly

[V.W.Dave]

I know I will be shot down over this but the best springs are 100% custom made ones to suit exactly your need.

What I mean by that is get your self 4 or so old sets a mixture of front/rear, new/old, old lux/new IFS rears and make a set to suit your need. It will take some time to perfect them but in the end you will end up with a better spring set up then anything you can get off the shelf. The main reason this is best is the older load leafs they are stiff but still give a little flex. The newer springs have a longer flexier military wrap but they are a little thicker and less likely to brake and better for axel wrap.

I Think you get the idea.
If you are really going to stretch it out you can also look at rear leafs out of late model ford utes. They are long strong flat and flexy.

[whitey86]

well im thinking ill use the old lux springs i have out bak just to get mounted up and then play with leaf numbers and shock set up when its going

[lump_a_charcoal]

I would plan to run an antiwrap bar like Alien has as well. If you plan it now, you should be able to incorporate it nicely.

[zook4fun]

why are you looking at doing all that work and keeping it leaf sprung? you will have to do a huge chassis extension to move the front diff forward enough to get the balance the car right. have a look at 3 link set ups, very easy to set up and easy to get signed off

I wish I linked mine from the start. but we didnt have the space when I started my build.

I was discussing a future engine swap with an engineer today and he said the largest size that can be passed in a sierra is 3.4 litres and then only if it is naturally aspirated but that is still alot of motor for a little zook.

I spoke to my mate in perth who does the engineering for vehicles , and he said there is no limit to any engine size or power just as long as everything else like brakes chassis etc are upgraded as well , but you have to register it as something different i cant remember what he called it , i thought he said hot rod , but that doesnt sound correct for a zook, will check again

[troopy94]

He might have been refering to registering it as an icv or Individually constructed vehicle. Just an idea have you thought about putting the zook body onto the chassis of a vehicle that could legaly run the v6 eg.a swb patrol and that way you would get the diff and brake upgrades needed to pass engineering aswell as the suspension to support the extra weight.

[Guy]

I have never quite understood the adding a V6 to a sierra ..
heavy iron motor, wheel base extansions, lux diffs and leaves, etc .. it is still going to be narrow, with the extra wheelbase you will have less space for a fuel tank, so thats going to suck for a tourer, battery will need to be moved to make space in the engine bay, so that will take up precious space in a SWB sierra body. Again not great for a tourer.

If you start out with a LWB you can pack alot more in .. or look at V6ing and SAS swapping a Vitara.. Honestly for a tourer it makes way more sense, Tranny tunnel is bigger to begin with, more space, AC (nice for a tourer) more wheelbase etc .. I guess it depends on how you define tourer and what your idea of touring is.

[hillbilliywheelchair]

yeah steve that is the sort of thing i was thinking if i was to strech it but with less Comp truck look

your going lux diffs and commo v6 but dont want a comp truck sorry comp truck look lol i honestly do not see the point. and then to ask for advice and everyone gives u there advice which there advice all sounds good and even with some personal expeirience and with none of them really saying how stupid this all sounds and then for u to go and crack a tantrum saying your doing it anyways, why bother posting it up at all good luck with your build oh wait ill give my 2c worth, the best thing about a como v6 is that there cheap but with a guy like u with more cash than sense why not a new alloytec v6 if it must be a v6 at least get a lighter one

To state i have more money than sense is personel , and i dont want to start that shit.
As for the alloytech well first marks adaptor dont have any adaptor in stock to mate it to Lux Xfer
the Vz wich came with the alloyteh run a body control module wich makes life a whole lot harder as i would then need to run 2 aftermarket computers one for the motor to eliminate the BCM and one to take care of the box , buy using a alloytech i make more work than the gains outway .

Thanx to steve, Gwagen , 94troopy and grimbo u have helped
To Johnsy86 think before you post , just my 2C worth thats all

alloy tech where avalable in the rodeos to
still i dont like the idea of a heavy lump in a very light and nimble 4wd
i would personaly be looking for something all alloy to lighten up the front if you really want to go a v6
if not why not the vit v6 and box?
and remember an icv has to comply with 2011 standards so you may have to go gas to make it pass emisions

[Rhett]

There isn't that much bettween the alloy tech and the ecotech. 186kgs- 168kg. But there is another 20 or 30 kw to be had. In my opinon both are far too heavey.

[mrRocky]

g'day mate i like your enthusiasm, but there is a couple of issues i will point out for you, the first of which is legality, i'm in perth and i can tell you it aint guna be legal in w.a. no matter how much $$$ you throw at it.
Secondly by only going 31"s on lux diffs you will have much less clearance under the diffs than a sierra on 31's with standard diffs, so you will effectively be making it less capable than your zook is now.
Iam currently installing an n/a sr20 in my lwb zook that has around 150hp and while this isnt a heap of power its going to be plenty for anything i could want to do in a zook even race it. The best part is they are only $600 for a low km donk.
The guys on here will help you out but understand at the end of the day its just an internet forum not the be all and end all so if you get flamed a bit just switch the comp of and get your hands dirty doing what others said cant be done.

[whitey86]

Thanx for all the advice guys , conversion has started so i will let you know how it goes

dont forget pics for future people wanting to do it.

[duncan]

I have done this conversion and sold the vehicle it still runs and is a freak of road going everywhere far bigger dollar rigs go with no fuss but it is a comp car definatly not road going.

it runs a VN series one but similar to your VS also turbo 700 and twin hilux cases with reduction gears.The front diff sits in front of the motor for clearance and is a 3 link set up with 2 inch lifted jeep TJ wrangler king springs coil the rear is standard 80 series front coils 4 linked but the diffs sit under the ends of the original chassis getting out to 110 inch as a comp play car its great but as a road car sorry to agree with everyone else go for a g16b or something silimlar and Im in Perth if you have any questions.


Forgot this thing is on comp spec 40s with hilux diffs and 80 series steering box

I reckon for all the effort thats involved in fitting a commondore motor to a sierra ( I know, as I have done it!!) you should throw that crap out and fit a 1UZFE instead. All the same issues with clearances and driveline length etc, but you get a lighter, more powerfull motor and only 200cc increase in capacity over the GMH lump of shit.

Plus they sound INFINATELY better

[whitey86]

Gutless . I agree with the 1uzfe idea but i already have a v6 and have access to heaps of spares .
I did look at using the 1uzfe but as i have got all the diffs gearboxs ( im using hilux manual ) and the V6 for the cost of buying a 1uzfe im gonna give the v6 a shot

I will post pics as i go

I can understand where you are coming from but remember.....

The poor man pays twice!

This is a huge undertaking, so make sure you get ir right the first time. Even if that means spending some more coin. And the Lux box would be perfect for the 1UZFE. Off the shelf adapter kits!!

And I have mentioned this previously on outers once or twice But the massive amount of weight that the VN-VS 3.8 adds over the front axle is the last nail in the coffin for this redundant conversion. Its an under powered, overweight, old tech motor. And from my own personal experience with conversion (I feel qualified to add this comment, whereas others here are only passing on second hand info, and recycled posts from the interwebs) its a shitty idea, a waste of the money that it WILL cost you, and a great way to ruin a sierra.

Please re-consider the 1UZFE
