Hicas Models Only Comes With Open Diff

[noisia]

i ordered my 2way today, and he wanted to know wether i had an open diff or a vlsd. he says if its had hicas its an open diff.

anyone back this up?

I doubt that's true. I've seen specification sites that say HICAS and LSD. At least they did for R33's. Considering pretty much all Skylines have HICAS I'm sure this would be common knowledge if it was true.

[Kinks]

all skylines came with HICAS and a viscous LSD, with the exception of some (rare) examples that have an active LSD instead. You can tell an active LSD because it has a light labeled ALSD on the inside of the tacho/speedo circle.

the viscous LSDs aren't as bad as an open diff but they do let one wheel spin a bit before the other will lock up.

I have hicas, my stock diff was viscous.. in my 91 r32 type m.

lol you would be better buying from someone who knows what they are talking about. r32 gtr for example had mechanical 2 way diff and hicas

hmmm weird, guess i will have to call him up and say i got vlsd so chuck me that 2way. he says that theres a difference in 2ways when it comes to having a open or a vlsd...i was like? i have never heard of this!

[Duncan]

nope me either, also sounds wrong.

once you change the centre of the diff (viscous, mechanical etc) the only other problem is the number of splines on the half shafts - these do vary between models but if the bolt pattern for the driveshaft is the same it doesnt matter either.

[bubba]

Yup, lies. I *had* hicas in my 32 and I have the factory lsd (not for much longer.. 3.9 2way ftw!)

rang him up, and said well i got vlsd, so chuck us the 2way to suit, anyway after some explanation he thought i had an s13 the whole time, which has 4 variants when it comes to aftermarket diffs, so was a communication error in both behaves. anyway so all sorted, filthy 2way coming my way!

cheers guys!
