Thinking about throwing some money at a Torsen at some stage to replace my vLSD, which doesn't seem to limit much slip wink, I get sick of lighting up the inside wheel on tighter corners.

The most common diffs for sale seem to be 4.3:1 (or is the NA8 LSD a 4.1? reading mixed things now), but I'm not sure what ratio the NA6 vLSD is to compare?

Its got plenty of power to pull longer gearing as the rev-limit in 5th is very accessible (on a racetrack of course occifer) if the difference goes that way.

Apparently with the 1.8 torsen I'd have to change axles too, how difficult a job is that?

The 1.6 final drive is 4.3:1 UK 1.8's have a final drive of 4.1:1

Any Japaneese MK1 1.8 special edition is based on the 'S-Spec' which has a TorSen Diff and a lower final drive (relative to the UK 1.8 cars), of 4.3:1...

So the final drive ratio for your car won't change unless you somehow manage to find a UK LSD, or you use a 6 speeds diff which will be either 3.9:1 or 3.63:1

When fitting a 1.8 differential to a 1.6 car you need the prop and driveshafts, it's not a hard job by any means, though some people struggle to remove the driveshafts, you shouldn't need to, (and if you do, they have a snap ring holding them in place so a sharp tug should extract them.

Took me and a mate 1/2 a day to do his, when I did my dads took a similar amount of time, but his car fought every step of the way due to everything being coated in a thick underseal.

Thanks, I certainly don't think I'll be using parts from a UK car wink but will try and find out what diff the NZ-spec 1.8 got.
