S13 Auto Sr20det Diff / R32gtst Manual Diff

[bubba]

Want to get an S13 auto diff (3.9:1) and have my Nismo 2way installed in it then swap housings in my R32. Is this possible?

To my limited understanding, the crownwheel and carrier setup is identical, just wondering if the housings are aswell? I would hazzard a guess and say yes as I think S13's and R32's are pretty damn similar in the rear end setup.

yes. you can do it that way.

You will need to swap the back cover and ensure it is/isn't abs to match your current housing.

[bubba]

Cool, so the back covers are different? and the housing differs for ABS?

[BHDave]

yep. abs housing is a bit longer and has a plug up on the snout. Output shafts may need to be swapped between the diffs as some s13's have a different output flange but thats no biggie as your r32 ones will fit and you'll have it all apart anyway.

[bubba]

I've got brand new output shafts that came with my Nismo diff so that's no drama, I'll just make sure I get a non-ABS housing.

Cheers Dave!

as previoulsy mentioned use the R32 rear cover as it has better cooling we used to fit R32 ones to S13's.... some R32 gts diffs have larger crownwheel bolts but i have only seen this twice.

mine had that luckily the nismo center also has the larger holes to suit
