I've been looking into it and from what I can tell so far none of the compatible stock transmissions came with LSD.
The mechanical 1 way for the E12 Nismo S ( hr16de model) uses the same gears and transmission so it should work.
Bonus is the stock FD is 4.055 the Nismo LSD is 4.214.
But it's pricey at 180,000¥ plus shipping. Plus install. It would totally transform the car tho.
The open diff is useless. When one tire slips all power goes to the tire that slips.
This Nismo 1way would change that.
