Bambi, 1st off do you want to drift your daily or mountain/canyon run your daily? 2nd, the 240 and J30 vlsd unit is pretty much the same besides the ratio (ring gear) and the position that the vlsd unit inside of the case because of the thinner(240) and fatter(J30) ring gears so the bearing shims (look @ post #127, part 21) are used in different spots to make the ring and pinion mesh correctly (edit{ and the axle output shafts are different sizes due to the differences of ring gear thickness}). And obviously the casing is different due to the S14/J30/Z32 mounting style of the diff to the sub frame and the ABS sensor. If you want to drift look at Evo's and holslut's posts and you can find that their combos of shims make the diff lock up,, If you read my post #128 ill even copy and paste it for you,,>>"" my stock shim size out of my J30 was 1.13 and the other one around a .80. I think every J30/240 vlsd has its own diff sizes from the factory. What I did cuz I didnt want such an aggressive rear end (canyon/mountains) is measured the slack with the stock shims in place with a feeler gauge with the unit together. so there was .20mm in slack and I added up the 1.13 shim size and added .10 more for stiffen it up and got 1.43... 1.13+.20+.10=1.43 and conveniently there is a 1.43 shim and went and ordered from Nissan. I have only driven the car around the neighborhood with no chirping or ratcheting. Still need to go on a better test drive w/o a slipping clutch to get a better feel of this diff. plus I still have the other shim that I replaced and if needed to tighten up a lil more""..
Now I have driven this car with a brand new clutch with the shimmed vlsd for 2 months.. its nice, no grinding or chirping. will lock up most of the time on a wet surface not hard but just enough to get you sideways.. and I only added .10mm of shim after the slack was accounted for. I could of added more like .30mm over (not adding that size shim on top of another , ex, (stock shim[1 side] 1.13) +(.20 slack I measured with feeler gauge)+(.10 what I thought would be enough to tightened it up)=1.43mm which is nissan part # 38424-40F81 ..with a lil searching online you can find the 20 or so sizes/part# you can order from nissan.. If you have any questions you can ask me @ the Irvine meet .. Holslut has a valid point if you have read everything you would of noticed that everything in this post has been mentioned somewhere in this thread,, no need for attitude,, just sayin. hope this was enough info for you to start on your vlsd ..
