Tom63050 Posted January 9, 2005 Share Posted January 9, 2005 I'd like to know this so that when I look at ads I can tell if the car has one. I really want one for my lifted Loyale and am willing to buy a whole car to get one, especially if it is a fuel-injected 86 or newer wagon. Then I can use the D/R 5-speed and have a spare motor too, plus all the little nickel-and-dime stuff. Basically my own compact junkyard. Link to comment Share on other sites More sharing options...
idosubaru Posted January 9, 2005 Share Posted January 9, 2005 try doing a search, you'll get tons of commentary on this subject. easiest to get a 3.7 lsd and convert your existing open 3.9 using the internals of the 3.7. i believe there's information and a write up addressing this. do a search on this group and you'll have plenty to read for quite some time, with lots of lists of vehicles...

GLCraig Posted January 9, 2005 Share Posted January 9, 2005 The parts books say that a 3.9 LSD was an option on the XT6 but no one on the board has actually seen one. All of the other LSDs will have a 3.7 ratio. Here's what's involved to take a 3.9 and making it an LSD using 3.7 LSD parts. http://www.ultimatesubaru.org/forum/article.php?a=36 Link to comment Share on other sites More sharing options...

I sent Liberty an e-mail asking them to verify that part number as being a 3.90 ratio. I'm not surprized that they haven't answered. Link to comment Share on other sites More sharing options...
ezapar Posted January 9, 2005 Share Posted January 9, 2005 The parts books say that a 3.9 LSD was an option on the XT6 but no one on the board has actually seen one. I've seen one. It was on/in a XT6 on it's way into Aaron's Auto Wrecking. Couple years ago. Link to comment Share on other sites More sharing options...
idosubaru Posted January 9, 2005 Share Posted January 9, 2005 best bet is to build one from a 3.7 lsd unit and an open 3.9. keep your eye on ebay as well, but they'll go for 300+ and i've seen 2 in the past 2 years. you will likely wait a long time before you see one on there though.
