Austarion

Can anyone tell me exactly what needs to be machined down to make this work?

Take a look at this forum and search for LSD in the technical section. From all the information i've seen over the years the diff in these EX lancers are the same as the scorpions.

If thats what you were planning then this would be the best place to get the info. As far as i know there hasn't been anyone to do this conversion in AUS because for the cost of the machining and the price of the small starion LSD diff centre you would be pretty close to getting a more common LSD diff customised to be able to used in a scorpion or sigma.

Not worried about an LSD, I just want a somewhat shorter ratio than the stock 3.308. The reason I asked is because I can't find any info on what cars used the Jap 10-bolt diffs other than the Scorpions and EX lancers

the sigma wagons did, but u guys in oz may have different sigmas to us here in nz

Most Aussie Sigmas ran Borg-Warner diffs. But.......... there are some exceptions.
