R32GTSt manual is 4.3:1

I think you can get some pretty short ratios out of Nissan Serenas

sweet ill look into it, do these diffs bolt strait in or will i have to swop housings?

Best off using the housing in your car and swapping the centre, if it's an R200 it should bolt right in but you may need halfshafts/axles to suit that centre.

In my 32gtst, I know the S13 housing bolted right in. Don't know about R33's, S14 might bolt in?

When changing ratios though, you need the CROWN WHEEL and the PINION GEAR. Find a diff place to put them in your current centre in your current housing.

As far as axles go, I think the S13 had fewer splines than the R32 but I got new halfshafts to suit with the Nismo centre.

GTR's axles are thicker and thus have more splines, won't fit in to a GTSt centre and GTR's have a 6x1 bolt pattern on the axle, GTSt's mostly have 5x1 and S13's mostly have 3x2.

I just put the old VLSD out of the 32gtst in to my Stagea to replace the standard open centre. What I discovered was that the open centre halfshafts were smaller than the VLSD, luckily they both still used the same 5x1 bolt pattern. So the 32gtst centre and halfshafts fit in to the Stageas open centre housing and I kept the original Stagea ratios (because it's 4WD).
