i loved the 2.77 even with the crossflow and T5 
for engines that make good torque from idle to 4000rpm like i had, My ute was happy doing 1850rpm in 5th with 2 x 100kg adults, 2 motorbikes in the back with 2 chainsaws and 6x4 trailer level with wood on the highway(would have been same fuel economy in 4th but less noise in 5th)
 
if i didn't have overdrive i'd have tried the 2.53 for sure if they were common, i reckon 1st would be no worse with a single rail (6cyl one) as My XD was with the 351 version single rail and 2.92 gears i had once. 

Same hemisphere as a 2.77
 
Yeah, but whats it good for? 2.77 is too tall in my opinion

Barn find rare 2.53 b/w gear set $900 Ono baahaaaaa

Agree 100%
 
I cant understand why anyone would want a 2.53 ratio crown and pinion, other than to say they have one

Same hemisphere as a 2.77

wait until i get it finished then take it for a drive and do a few tests,this diff could be worthy a rebuild in my book and while its at the diff shop get them too fit the 25 spile lsd centre😛

the XE diff will be 25 spline 
so if you wanted to run 28 spline to my knowledge you'd need(i'm not 100% sure)
 
2.77 LSD center,  if wanting LSD
not sure if you can retro fit 4pin setup into them? (thought there was a 28 spline version though?)
 
if you wanted those axles you'd need the 28 spline spider gears in the center(no idea if they fit)
 
i think the EB axles will fit the drum diff if you put the correct bearings in and holders on? (never tried, haven't read about it for well over 10yrs)
 
i think you can convert from drum to disc by drilling new holes in the disc caliper mountings and clocking them different (the flange on the diff is rotated differently for drum and disc. )
 
@Thom may remember, @gerg may know even 
 
if it was Mine, i'd be getting a 2.77 LSD diff with discs from an XF ghia/ZL fairlane etc (some were 2.92 for no apparent reason in my opinion)  and then having the gears fitted to it. leaving it 25 spline unless you are going big hp (stock 351 would be fine with 25 spline, I never had 28 spline in anything i had not even the 1UZ conversion) 
 
 

i have a set of 28 spilne axles here from a xg ,can they fit on that drum housing ?like a retro fit 

i would expect it possible if you had a diff dude who was willing
 

i wonder can those gears be put on to a EB  or ED sedan diff

it was mentioned 2.77 when i hears about it

hey i thought of a good question this afo,would the 2.53 diff be good for better burnouts ? like in 1st gear i mean,instead of that sweet spot between 1st and 2nd,just hold it in 1st ?

pretty sure if you've got enough power you'd just start in 2nd or 3rd 
i remember one of My cars would actually stop it doing a burnout on grass even if you held the brakes on hard. 

next question is what does the 2.53 gearset belong too ? the 2.77 diff housing or the 2.92 ? maybe thom knows.

I've had quite a few with that combo, 2.77 or 2.92 diff with T5
had the XE ute smoking the clutch on a hill start in reverse with 2 motorbikes and heap of firewood scattered between/around them.. (was fine still, that was a heavy duty clutch i always chose thought, 30% heavier than stock so not to crack the pedal box/firewall etc)
 

Had a mate with an xf that had been converted from auto to 5 speed ,,
 
burnt 3 clutches out “ under warranty “ 
trying to drive up my driveway ,,
 
my ol wood hooker ,,, 
kb laser with 1500 manual with 3/4 a tonne of wood in it ,,,   Piss it in 

OMG!!!!
that's got to be stickied, plastered all over the interwebs and facebook groups
 
IMAGINE that ratio with a 6cyl single rail, with a clevo, wouldn't need overdrive  and the 351 torque would pull away in 1st gear like it's nothing

I have been waiting all afternoon to post this picture,I got under my new xe project car and here it is ladies and gentlemen the 2.53 borgy,I'm sure I'm reading the tag correctly, 1st one I have ever seen in the flesh and owned.

I  have never heard of the 3.12.
 
I was replying regarding the 2.53.

Efi auto would have 2.92 or 2.77 in sedan.but interesting talking point is the 4 speed single rail in efi sedan ratios in the gearbox are different

while reading about the t5 thread before,in rememberd i had an idea of putting a single rail behind this 472 c.i,a shop sells a big block alloy bell to suit top loader or single rail,as its not a race engine,its 100% stock,a 008 351c xc xd xe single rail should be fine imo.

All done,I had to buy a tool to put the oil screen on,and my stand is leaning over,maybe I should take it off ?
