Hi guys,

I own a mint condition MK2 RS2000 and I'm looking to upgrade the diff. The old "English" style axles aren't really meant for increased power so a common upgrade is to changeover to a 70's Toyota Hilux Diff, model number RN25. These are getting rarer and rarer to find so there's talk of using the Volvo 1030/1031 amongst Escort enthusiasts. There appears to be a large amount of parts available for them and they are fairly common.

I beleive I'm after a 1031 with a 3.71+ ratio inside. I understand the 30/31 are slightly different and you can't transfer the diff centres between each other. Correct?

I'm looking at getting an LSD eventually and was wondering will all LSD's fit inside either a 1030 or 1031?

I'm also in particular after a LSD that uses clutch packs. What brands are out there that will work? It's for the track/race/tarmac rally.

Whats the width hub to hub?

Cheers guys! (IMG:style_emoticons/default/thumbsup.gif)
