what i would recommend you do is save your money and buy a Quaife unit or OEM S15 Helical unit (the s15 unit REQUIRES s15/R34 29 spline output shafts, 28 spline output shafts will NOT work) if youre in the market for a helical diff.
i personally run a helical S15 LSD in my S13... it slides just fine. it doesnt lock up like a clutch type does, but ive yet to have a single issue where full lock is required (helical/torsen dont lock, they just transfer torque as they are a gear base instead of a clutch base). im building my car for reliability and ease of driving, so the HLSD works just fine for me as its 100% silent, maintenance free (outside of changing the gear oil every 20-30k miles) and NEVER wears out!
if you want full lock and something that isnt a pain in the ass driving around town, go buy a 1.5 way or 2 way clutch type LSD from Cusco or Kaaz.
