Merv,
I have my S15 diff sitting under my bench for about 18 months for the reason you stated. The motor I have is only 4ltrs, but will rev to 6500rpm easily, which makes 1st gear usable with a 4.1:1 diff(and fun to drive). Once I bolt on the supercharger I will be changing the diff over.

The price you were quoted is a very good price and these diffs will only be harder to come by in the future.

That picture Sambo attached looks as though it is a S15 diff. Note the position of the ABS sensor behind the drive flange and the 6 bolt flanges on the drive shafts.

Stumpeater,
The Cobra that I know that has had the S15 has a T56 and did take off in 2nd gear all the time with the R32 diff.
If you are going use Ist gear as you described, replace the front rubber bushes with steel bushes. I have been told that it is not a pretty sight if the bushes rip out under acceleration.
