Jeez you guys arent really helping the OP.

 

Hilux diffs are quiet large in the carrier section. This will hit the floor of the rolla. Commodore diffs are a bit smaller, can hit but less often.

 

T-series will break with abuse on anything above 150kw. I know cause i broke one. That said it did last 4 weeks. ;)

I have a custom diff being made for me, I sourced all the appropriate parts and gave it to Graham at boss engineering. I bought an EF/EL falcon disc brake lsd diff with 3.45:1 ratio, a blown ke70 diff, and an r31 center for the 3.89 ratio, all up it has cost me just under 2K.

 

I figured doing it this way it was going to be about the same cost as a rebuilt T-series with lsd. Once finished it will have commodore center housing with the flacon lsd and r31 ratios, ke70 axle housing with falcon ends for the disc brakes, shortened and re-splined falcon axles and disc brake. The brakes also run internal drum handbrake. The brakes also match the front up grade i have from hopper stoppers, running falcon 5 stud all round.

 

So it should be unbreakable, running a gze with sc14 and aftermarket ecu.

Perhaps i should weigh in with my $0.02.

 

 

.... Forget T and S series diffs, unless you are an idiot who enjoys the smell of diff oil - cos you will be swaping a LOT of centres and axles.

They are farken piss weak. Axles are about as thick as a 2B pencil and equally as strong.

The gears in the centres are equally poo..... they chew out at the slightest sign of being placed under load.

 

How do i know this?

AE71 4age = killed 3x T series centres

AE71 4agte (116rwkw only) = kiled 1x T series centre, and had one axle twisted at the splines

RA28 18RG = killed 2x T series centres

 

.... and S series is even more sh!t than T series.

 

 

So what does Witzl recommend?

 

F series (eg, MS113, MS123, etc)

Volvo 240.

R31.

Commodore.

Hilux.

Anything similar.

 

 

My personal preference for your application is with the F series diff.

They are pretty cheap to buy, easy to do a disc brake conversion on (in fact, i think MS123 is already disc brake), and you can get a Detroit Trutrac torsen LSD for them.

They are also a lot lighter than the Hilux G series diffs, and the carrier isnt as large either.

 

My personal choice for me is the Volvo 240.

Comes with disc brakes (twin piston), axles of death (bigger than hilux), wouldve been babied their whole life, aftermarket centres not an issue (dana 30), and they are bloody cheap usually.

I have a lot more power to pay down than you do though, so this might be overkill for you.

 

 

FYI - i had a quote from Craft Diffs to get a volvo 240 diff converted to suit my KE70, including new bearings, weld and redrill axles for 4x114.3mm, and fit a trutrac lsd centre that I supply.... was around $950 iirc. Add about $600 for the diff centre inc. shipping, plus maybe $200 to buy the whole volvo diff..... and you have a sub $2000 diff that will handle over 200rwkw.

 

 

FYI - here is my volvo diff in the KE70

Fyi.... here is a link to a crapload of info on the Volvo diffs, which is a Dana 30 diff: http://people.physics.anu.edu.au/~amh110/Diff_LSD/diff_lsd_volvo_dana.htm

 

 

And here is some info on what cars you can get an F series diff from:

One point that I should recommend, is to find a diff with similar width to your stock diff (wheel mounting face to wheel mounting face).

For example, the KE70 stock width is around 1410mm, and the volvo 240 is 1420mm. Thus very close, and means you don't have to get the diff shortened at all!!

 

Most of the toyota crown F series diffs are around that 1400mm width mark iirc.... but a trip to a wreckers will anser that for you!

Actually... just confirmed that MS112 diff is 1410mm also.
