Diff Upgrades For Ke Rolla's

Featured Replies

a day at a few different wreckers and not too much luck...

 

was looking for a ke25 sized diff, which is 1320mm mounting face to mounting face

 

corona mkII - too wide 14??mm

r31 skyline - too wide 14??mm

hiace - too wide 13??mm

L300 - too wide 14??mm

chrysler lancer - 1320mm!

120y - couldnt find one but is meant to be close 13????

commodore - too wide

datsuns - some possibilities, will check out a few soon

escort - 1340mm, little bit too wide

ke30 - 1370mm, too wide

ta22 - 1370mm, too wide

volvo - too wide

scorpion - too wide

hilux old - 1370mm, too wide

some vans - 1370, 1370+ too wide

 

so not too many cars that would have suitable width diffs :sad:

 

oh well looks like a shortening job then$$$

datsuns - some possibilities, will check out a few soon

I'd be researching more into the Datsuns - However, its also very common for Datto owners to install Corolla diffs into their cars. So it might be worth asking a few Datto owners why they change their diffs to Corolla items, (strength reasons or ratio reasons)?

SR5 LSD

 

or you could just chop 1m off a 9":jamie:

For some reason (maybe because the Datto1200 is very light?) Corolla diffs seems to stand up to a lot of abuse when installed in Datsun1200's. I now know of 3 Datto1200 race cars with locked Corolla diffs, all pushing a fair bit more power than my KE35, and I've only ever heard of one of them breaking one axle (in the 2 or 3 years it's been running). And this is in a car that was pushing like 140+hp atw...

Get a Commodore LSD up ya......

 

Id love to help, but my lsd was professionaly build and installed before i had the terror of a beast, so i donthave much info...

 

but the skyline and commo lsd's are the same.....

 

You should be right with the standard one for now anyway,

 

How much POWER did you say you had??? :jamie:

My friend with a Dastun 1200 coupe with 180hp@wheels FJ in it ran a locked galant diff the whole time he had it on the road....He said he had no problems with it.

 

My other friend's rolla with the 202 in it has a locked KE30 diff and it has lasted a fair while now including a drift day...It broke it's first axle a couple of weeks ago, and let's just say...this diff IS NOT being looked after haha. This thing gets dropped from stupid revs in 3rd and 4th gear into instant donuts...almost everyday

I don't have a problem with a weak diff, just a weak engine! :abuse:

 

But not for Long! :jamie:

how much power you goin to have flowin through this thing?

 

in my old ke20 i hada locked banjo diff with a worked 4k and it was strong as fuk.

2nd gear ringys aslong as i wanted every wkend and it just took it.

 

in my ke20 with 250 iv got shortened and locked borg warner out of XE and its bullet proof.

 

some food for thought

cheers scott

i'm very proud of this: i managed to convince my mate to put a ke70 diff into his mk1 ford escort! he's locked it up and treats it like crap, running a worked 2ltr through it.

 

its beter for lots of reasons such as:

 

better ratios (best escort ratio thats affordable is like 3.7 or something)

bigger drums

panhard rod

swaybar mounts

wider track but still fits in guards

114.3 PCD

better handbrake setup.

 

they are good diffs really, be good to have one in my ke11.

 

scott.

a mazda b1800 ute diff is very close to the right length. i have one in the for sale section. the reason why people run all these other small diffs with no problems is because they are locked. a properly locked centre eliminates the star gears and pin. this is the weakest link in any diff. it is very hard to break the remaining bits without excessive torque (or abuse). :D
