S14 VLSD into a S13 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Okay, so this is what I have so far:

It's from a S14 K's, apparently. Viscous (sic?) LSD. I have a '89 S13 coupe, and some people are saying you just put it in, others are saying I need to forge this and that out of the fires of fucking Mordor for it to work, so what's the dilly?

Any help is appreciated. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/cry.gif" border="0" valign="absmiddle" alt='

A differential needs to have the preload and backlash set when it's dropped into the carrier.  It's a pretty complicated process with a lot of adjustments to make.  You can pick up a book and try to do it at home, or you can have a transmission shop do it.

that looks like a mechanical lsd to me, a viscous is a sealed unit.  If you want to do it right then you want to take it to a tranny shop.  If you do not do it correct and get too much preload or just miscalulate a single adjustment then your gears grind and ruin the lsd.  also you need to get new bearings and races unless you have the old races and know which side they came off of.   The bearing have to be preesed off/on by a machine shop.  The output shaft is another thing you need to look into.  You have to get one from another lsd and the opposite one that you have(the other side) cause they are different ones for each side.  I think you can get them from a dealer but they are like $130 or something.  Also on either side of the bearings are spacers that have to be spaced correctly also. That is all i can think of right now.  Good luck.  If you have any questions email me at [email protected]

Nah, that's a VLSD.  The viscous coupling itself is inside between the spider gears.
