Sorry but its anoter VLSD Question - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I've tried searching around for the answer but i couldnt find anything to help me out because i have a 180sx VLSD, but the thing is that i have to open up the housing and remove my old LSD...From reading around i found out what kind of tools i'll need but i dont know if i need to do an modifications. This is kind of what the 180sx VLSD looks like:

As long as you have an LSD already you can easily pull the old unit out, install the new one, and reshim it if necessary. If you have an open diff you'll need the correct output shafts also.

whats this i hear about differnce in install for a j3o diff (which had abs) into an abs vs a non abs s13?

can you install a vlsd into a stock open diff?? and if so are the axles the only special thing you would need?

Output shafts, not axles. Axles are the same.

Hate to tell you this, but I have no idea what these guys are talking about.

If you are swapping the internals, you reuse your ring gear, however; it's going to need to be reshimmed. Shim kits are about $100....just not cost effective to do it once off. Plus there are some special tools needed and in general rear end work

is sort of an art (backlash and all that).

You are much better off just buying a center member complete even if you have to swap covers.

I have thought about the HLSD from a S15 before I decided to do just a VLSD with no abs from Japan for my 98SE. The HLSD would be close to $600 once shipping and the output shafts were sourced, then anywhere from $50-200 for the service/install (not to the car just the rear end assembly).

I figured for about twice that I should just get the Quaiffe and the lifetime no questions asked warranty that goes with them.

Of course before my suspension, turbo, etc spending $600+ on a differential is just plain not practical.

Not so...

If you pull your ring gear, swap the open unit for a VLSD, and put it back together with every shim in the exact same spot...no problems.

MANY, MANY people have installed KAAZ diffs in this manner...not even an OEM part...and have not had to reshim, as the backlash and stuff has been in spec after the install.

I have installed a VLSD into an open diff housing with no ill effect in over 12,000 miles...

As you pull everything apart, lable and keep it in order...then put it back EXACTLY as it was...you'll have no issue.

Now, it's still a PITA, but do-able.
