Diff modifications

Post by Stephen22 » 16 Jan 2019 03:29

Good day Gents.

I have a 1972 510 4 door with a Lexus V8 engine in it.
I have a problem with diffs not lasting. The Subaru diffs are really rare to find in South Africa.

How difficult would it be to modify another diff for example a BMW diff they really popular here?

i would put a R200 from a 280z or zx if those are readily available- - cheap and definitely can take a v8-- i have a ford 5.0 in a Z and have yet to break a diff-- now half shafts are a different story i manage to blow those- and time to upgrade to CVs

Yep. Even an R180 from a newer subi would probably be up for the task if it uses some good oil and isn’t hooned. Different types of LSDs available (in NA anyways).

I would exhaust a few of the easier options before I redid everything for a different rear end.

stephen is in south africa , witch makes a subie R180 very hard to find.
R200 open diffs are however available .
i managed to fit an LS unit from an S13 200SX into a longnose R200 with some modifications.
i still need to have the sideshafts made.one big downside of this is the s13 LS unit needs the S13 cv cups/input shaft to engage the LS unit.and it took me a very long time to source the input shaft's/inner cv's .
Progress is slow, but it is progress non the less.

you can get a phantomgrip which pushes the spider gears out and give it a sort of posi traction- ive used one and it does leave 2 solid marks when launching-- - i think they were like 300 last time i got one-

I looked at those. Kinda scared of what it's doing to the spider gears. Anyone have any opinions on them? Sorry for the kinda thread jack...

That looks very clean! Did you do the swap yourself? Looks like the firewall was moved rearward somewhat?
