Most common DIY chain diff is the sierra unit rehoused....

fiesta is easier to convert diy as no machining is needed but an lsd version is dearer
sierra diff needs the bearing flanges turning down slightly to accept a cheap sealed bearing , if you can do the machine work then a sprocket is £50

how reliable are these on the road? I'm thinking that car diffs have lots of oil lubricating things. Chain diffs don't have a lot (if
any).

the main bit the oil lubes is the cwp, which is obviously not there any more.
The "chain diff mod" creates a "can" around the planet carrier which holds oil/grease around the planet wheel area to maintain
lubricant in that area.
lubrication is no worse than in a std diff.
The issue that bothers me most is that there is no way of preventing oil loss between the side gears and output shafts, through the clearances in the
splines.
I have asked about this many times on here and never had any sensible answer.
in autograss a bit of oil weeping isn;t an issue, but on the road it will be!

Can recommend (strongly!!!! ) JB Gears in Leeds for sprockets.
2 x 38 tooth 630 chain driven (alloy) sprockets bored and PCD drilled to my drawing, plus 2 x 16 tooth 630 chain hardened steel driver sprockets bored
out to my drawing, were £90 total delivered.

The solution to this is a thin O ring between the CV insert and the splined hole - keeps oil in no trouble, but the circlips are a pain to get back
on....
