LSD question

In the installation article under LSD's, the author states that Quote »From what I've heard SE's with ABS, HICAS, or S14 5 lug SE's w/ ABS all should have the LSD.[/quote] I have ABS and I have absolutely no clue if I have an LSD. What are your opinions?

Forgot to mention that I do not have HICAS.

super hicas are rare, you will have a super hica sticker on both side of the car unless someone paint over it which is unlikely.

chances are, you do not have lsd. You can check to see whether you have lsd or not by doing burn outs, or donuts and see if you have 2 strips of tire mark

the below is taking from 240sx.org faqQuote »I tried the most popular VLSD test while the car was up on a lift. I definitely have the VLSD, confirmed via other means. Namely, big orange sticker on the side that says VLSD.... Anyway, all forms of this test were done with both drive wheels completely off the ground. Here's what I found:

With transmission in neutral, spin one wheel by hand and the other spins the same direction. Both spin very freely.

With transmission in gear (driveshaft fixed), the wheel is much more difficult to spin, plus the other wheel rotates in the OPPOSITE direction.

With one wheel fixed (someone holding it in this case, could also be on the ground), either in neutral or in gear, it is very difficult to turn the other side at all, but it will turn given enough force.

I've heard that other VLSDs and other types of LSDs tend to react to this test differently. For instance, the Torsen and other similar helical limited slip differentials act just like an open differential when subjected to this test. However, the above is how Nissan's R200V VLSD reacts to the test. I'd assume that the Z32's R230V would react the same since it's of similar design, just a bigger ring gear.[/quote]

so if u do a burnout and have 2 strips u have lsd? ans whats hicas?

to be honest I don't really know about the 2 strips but you can kind of feel whether if there is a wheel lock or 2 wheel spinning when you do donuts

you have to do a burnout w/ the wheel cut. both wheels will sometimes spin going straight even w/ an open diff.

I thought only the s13's had HICAS. Jack up your car and spin a rear wheel and if the other moves in the same direction you have lsd.

mk, but whats hicas?

Post by **Fenvy** » Tue Apr 27, 2004 7:15 pm

you need to start searching

it looks something like this...

rc240sx wrote:well I dont remember what the acronym stood for. HICAS is rear wheel steering. The mechanism has steering arms coming out of the differential going to the rear wheels. It turns the rear wheels the same direction as the front wheels about 1 degree when it detects the car can use it.

or u could jack the back end of the car up and try spinning one wheel and seeing if the other spins the same way....

In 1991, only SE hatches could have a LSD. And LSD was only available as part of a handling package that includes HICAS.No HICAS (4 wheel steering), no LSD.
