Bullet Proof Diff conversion for any vehicle!

[DVSGAL]

really nice work mate, those rims actually really look good with the car, simple design but suits the lines, and the powder-coated white looks the goods too, esp with the blue!

The car is purple

[psshhhht]

lol, my bad, it is too... whoops...

oh well my point that it looks good is still sound!

[DanTurboLancer]

Hey Guys, and GALs
thanks for all of your comments!!

Well here is the final piece of the puzzle...
The tail shaft.

----------------------------------------

----------------------------------------

----------------------------------------



I had the work done at Gibsons Tailshafts at Edgeworth here in Newcastle.
I dont know the guy, but this is the second tail shaft he has done for me.
He honestly does excellent work!

Came to $450 (nearly choked when he told me, but when you put it into perspective)

Starion/Sig front Yoke, i supplied.
New Larger front Uni
Shortened Shaft
New heavy duty Patrol rear Uni
and he supplied the Rear Patrol yoke.
and Balanced

So the price isnt bad really.

I forgot to mention at the beginning, we tilted the front of the Diff housing down 3 Degrees.
Drag racers do this to help with launches.
But it was also to allow room between the Housing/Yoke, and the floor.
But in the end it wasnt as necessary as first thought.
I had allowed loads of room, and in the end there is heaps of space.

Dont go anymore than 3 degrees but, i was warned!

As I said this isnt just a conversion for Lancers or small cars,
its "For Any Vehicle"

The Diff takes the whole 4 Litres of oil too.





Now for the fun part,
I took it easy at first, wasnt sure what it was going to do.
Ive never driven a LSD before, only Lockers.

Bed the brakes in.
A couple of short sharp acceleration and brake.

It feels alittle heavy when you go over a bump and the back end drops down the other side.
But i have rock hard shocks, so they may not help.



But when i left a corner and hit 2nd and popped the clutch for the first time.........
Well its not shy about stepping out,
and with the short wheel base, the back end was constantly trying to overtake the front....







Just paid for itself!


Cheers guys

[DVSGAL]

LOL Dan...Just dont wrap it around a tree!!
And take vids

[psshhhht]

haha, fantastic mate, glad you're happy!

[DanTurboLancer]

I can see what Stealth meant about LSDs in light cars....

If you plant it in second, you run out of Opposite lock, and the back end is still trying to overtake the front...

Back off, and try to get the back end around, and you plant it again and it trys to spit you out the other direction....
Its a handfull.

And it is alittle too easy to start spinning the wheels in 3rd at speed, and doesnt give an indication its going to let go, it just does! and i havent had the balls to try it in 4th.


Hell of a lot of fun

[stealth]

mate treat it like a spool with respect
now you need to learn pedal control and how hard to feed it in
and with the kw's you got yeah it should do it 4th no worries
grow some then give it
but watch out for the tree's
cheers stealth

[Frosty]

nice work dan, wheels look pretty damn nice too!

those patrol diffs are known to be tough as nails for rock crawlers and heavy towing rigs. so you'll never break it in a lancer lol.

and most of all it's nice to see someone do something that hasn't been done before.

[FUGITIVES]

thread back alive!! hey Whats the lenght of this Diff From End To End , GH Sigmas are 53'' i believe

[DanTurboLancer]

Hey mate,
actually i never thought to measure and record the original width,
but its a damn site wider than stock Sigma.
Or in my case Lancer...



But you will definitely need to have Housing, Axles, brake lines shortened!

And i would recomend having the axles redrilled to suit your stud pattern.
That way you use your brakes and just bolt your wheels on.
The 6 studs are causing me troubles with getting a 4 stud adaptor plate made as the studs become too close at one stud....

If you are wondering diff width for mine in particular, its just the standard LA Lancer diff width, what ever that is lol.




Just to show you what the GQ Patrol is so you understand its size and width...

This an '89 GQ Patrol




and a Modified version...






cheers Dan

Oh im Glad you replied , we down here use the 620 720 and datsun 280c (cedric) diffs , theres alot of them!!! , but unwisely we dont get lsds for them, I already have a 280c with h190 centre in my car but its too damn wide and no LSD!!, i was going to go Independent R33 suspension but i think its too much work , Id rather try one of these ,

Now im hoping we have many of these Diffs available in our Foreign Used Parts places but I wanna make sure i identify the right one especially , the most i have is your pictures to identify and to spin one axle and see if the other spins same direction , is there any other way i can identify one ,

also these can handle big power in a built SR20DET GH Sig right? I really dont wanna be doing this and have my friends laugh if Something Breaks , do you have any good close pics of the lsd itself?

Thanks Steffan

[DanTurboLancer]

Where abouts are you?

I havent had an previous experience with these diffs myself, so i couldnt honestly tell you how reliable they are!

But i have heard of quite afew drag cars using them, and as someone mentioned earlier they are well known with the 4wd community.

The 33 spline axles, combined with the fact they are 10mm thicker than a 9 Inches axles show they are strong enough.


And as i mentioned earlier, the Clutch kits for rebuilding them are cheap as.

And if the clutches keep letting go, an Air locker for daily driving would be a good option.
Or a full spool centre if you are just out to give it a hard time all the time...



I will say it is a Heavy diff!
But so far alot of fun

[FUGITIVES]

made some calls and sadly they are a bit rare and expensive down here , $800 USD for the rear , i think im gonna just use a Datsun 620 and weld the Center

[DanTurboLancer]

well if $800 is too expensive, then the total cost will be too ;)

All the best with it!

[TR11KY]

good thread dan great to see something different! While i wont be following yours as im pretty well committed to a hilux diff now it was agreat read! Props too ya mate done well...

[BOOTS]

good work dan, props for taking a risk and trying something others haven't, of course there will always be that one or two who know best and there way is best regardless but again well done for thinking outside the box!

[oldn64]

..I already have a 280c with h190 centre in my car but its too damn wide and no LSD!!

Hey Steffan,

H190's do have a LSD flavour for the diff but if you have issues with $800 for the patrol diff I would suggest that the H190 will be too expensive for you too, not to mention the conversion costings. Definately would not look at a locker for it though, unless you like replacing axles and bearings.

Cheers

PS: Dan worse case scenario get new axles in the right pattern made for it.. ;)

[Smithy]

Looks good dan but that would be a lot of weight in such a light car. A commodore diff would be much lighter and cheaper for parts but I guess you used what you had available. My lancer has a VL commodore LSD and seems to work very well.Currently has 3.45 gears but will change to 3.90 if I can get it to hook up.Spins in any gear as it is.Need to squeeze bigger rims and rubber under it.Al least your diff will be unbreakable

[DanTurboLancer]

Thanks mate,

Yeah i was going more for Strong, not light,
Its a hell of alot of over kill.

I actually have a Commodore complete diff here, but after pricing, it worked out it was going to cost me more for a LSD, and i couldnt get the ratios i was after.
But maybe i didnt contact the right people?
I did extencive calling and web searching,
Someone might be able to put others onto a good contact.

I hear alot of Claims that people can do this, or they can do that, and it will only cost them ex amount of dollars...
but I havent seen any actual evidence of it yet.

As for the 3.45 to 3.9,
check with Stealth, he has alot of experience with diffs in Lancers with some power.
I am unsure how the lower ration would effect the light car?
It might cause it to spin worse?
Or it may reduce the Tourqe so that it will actually spin less???

3.45, she must have some topend speed!!!


And i totally agree with OLDEN64,
I have had plenty of street driven locker diffs,
and Loosening wheel nuts,
Tailshaft bolts,
Sheard Wheel Studs,
Bearings,
and Sheard axles in the Centre are very common.

[stealth]

i run 3.23's and a full spool the lsd's are unreliable at pace
and yeah it spins every gear no worries ,quite scary really but it does hook up its all about throttle control
cheers stealth
