View Full Version : S14 VLSD into a S13

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

A differential needs to have the preload and backlash set when it's dropped into the carrier. &nbsp;It's a pretty complicated process with a lot of adjustments to make. &nbsp;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. &nbsp;If you want to do it right then you want to take it to a tranny shop. &nbsp;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. &nbsp;also you need to get new bearings and races unless you have the old races and know which side they came off of. &nbsp; The bearing have to be preesed off/on by a machine shop. &nbsp;The output shaft is another thing you need to look into. &nbsp;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. &nbsp;I think you can get them from a dealer but they are like $130 or something. &nbsp;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. &nbsp;Good luck. &nbsp;If you have any questions email me at [email protected]

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