Quick question: value of 86 LSD tranny from non turbo car?
Hi,
I'm going and pick up a torque tube in the next hour and the guy says he has an 86 lsd tranny in great shape from a non-turbo car. How much is it worth? How much should I offer? I'm not really sure how the gearing compares to my non-lsd 89 S2 tranny... The tranny code is 220 right? And when I spin one hub the other should spin in the same direction right? Thanks in advance!

an LSD tranny from a given car (ie n/a, S, S2, turbo) will have the same gearing as a non-LSD tranny from the same car. the n/a tranny is weaker than the S2 tranny - I don't know how well it would hold up to the added tq of the S2; your non-LSD S2 tranny can be fitted with an LSD btw.
fyi, gearing on the lsd n/a is quite a bit different than that on the turbo; turbo should be turning 2269 rpm at 60mph, the n/a cars up to '87 should be turning a bit over 2300 (5th gear in the 87 and before n/a is similar to 5th in the turbo, but the other gears are quite a bit different), and the 88+ n/a should be around 2615 at 60 in 5th

That's a pretty good price. FWIW, I picked up my 944S LSD tranny for ~$700 from a lister couple of years ago.
Let me piggyback on this thread: what would a 85.5na LSD (taller 5th) tranny with 125k miles be worth if it's located in SoCal?

Too bad you are so darn far away.

it's non lsd after all, I turned one hub and the other turned in the opposite direction, but it is as clean as hell with low milleage. On a more positive note, I picked up a pristine torque tube and a powersteering rack/pump for $250 canadian dollars. If anyone is interested in the tranny, I can pick it up for a good deal, the guy also has a seat/door panel combo that I have never seen, the middle inserts are pinstriped white as well as the door panels... really cool to say the least...

Otherwise I would have gotten one years ago.

For those prices I am inclined to save more money and just have a new LSD put in one of 2 spare gearboxes. It may cost $1500, but at least I know it will work.

There are only a couple wear items inside the factory clutch type LSD, so they can be easily rebuilt. I have not priced the discs, but I dont think they are rediculously expensive. And they actually last a long time. Especially in a lower torque application like on an n/a or S transmission.
The only/cheapest aftermarket clutch type LSD that I have found is a Guard, and they are $1750. The dealer price is $2500 for new LSD unit. Yes, the torsen/quaife/torqe biasing diffs are a little cheaper.
Finding an LSD transmission, even higher mileage, for under $1000 is not a bad price, assuming its not missing any teeth on gears, pinions, etc....

This thread has the parts list for a LSD rebuilt (it's for a 951 tranny, though). I recently got these parts from Sunset, and it's even cheaper than what's listed. Now I just need to find a tranny shop to do the labor...
