OK, question of those who know more than me..

Did All ST205s (regardless of market) come with the rear torsen LSD?

Or was this an option?

And the ST205 and ST185 Torsen Rear diff are the same correct?

Yes - all came with a torsen diff.

I recall that the 185 diff is identical, except it has a clutch style LSD, instead of the torsen LSD. Perhaps the RC or RC CS versions have a torsen, which would make it the same as the 205.

OK, there was no factory clutch style LSD for the ST185, so that makes me question the "all ST205s have torsen LSD" line.

Can someone please confirm this. I found a diff in the UK for a decent price, so want to be sure I'm getting the right thing.

The 205's did all come with the torsen and it bolts right in. I've got one in mine. You are also correct about the 185 diff. IF it had a LSD, it would be a torsen but they are few and far between.

OK, thank you, I found a unit for $110 in the UK. I'm either going to have my buddy in London bring it out when he comes to visit next, or pay for overseas shipping.

I have a '91 jdm GTFour and the rear diff in my '92 is from an RC; both are torsen.

Well, I have an ST205 rear diff on the way from the UK for about $230 shipped.

Once it gets here, I will be pulling off my rear subframe for powdercoating, Poly bushings all around, and rebuild of the diff.

I am wondering if I should service the CV joints while I am in there.... Might as well now....

It wouldn't hurt to do as much maintenance as possible while you're in there.

That is a great price on the torsen too. I haven't looked lately but they were going for that much and more in the US before shipping.

Yeah, I found some guy in the UK who specializes in the ST205. He's a bit slow to respond, and his responses are a bit um.... "underwhelming", but he seems to have what I need.

The Diff itself was 80 pounds, and the shipping was 70 pounds... 150 pounds comes out to $237.46 today (it was a bit lower when I sent payment)

That price was for the entire diff and housing, but to save on shipping, I told him to pull all the internals and ditch the housing.

I would have had him ship the whole thing - hard to get it set up right, the shims can be fiddly.

Yeah and those shims take about 5 weeks from Japan. I replaced the bearings in mine and tried to get the right shims but couldn't get the clearances exactly right. I ended up sending it to Weir Performance and had their solid pinion spacer installed when they rebuilt it. Came back perfect.

it would have been over $350 to ship the whole thing.

I've shimmed diffs before, not too concerned

I do recommend getting the solid pinion spacer!
