Has anyone ever bought one? How much? Where at? Installed?

Just wondering, looking for something else new to blow more money on.
 
Welded $50
 
Ever consider the goodparts nissan differential conversion? Pretty simple and you end up with a modern LSD.
 
Nope, I never considered a nissan dif conversion, would like to hear ideasabout how it is done. Would be cool to get a 6 speed into it. I know where are serveral 6 speeds from some Nissans sitting. But a Quaife seems to be the easiest for my skills
 
The nissan diff conversion is simply a bracket set obtained from goodparts that mates the nissan unit to your current differential mounts. The kit also includes output flanges that mate the nissan unit to your existing triumph half-shafts. Then you just have to source a nissan diff. I found one on ebay for about $180. As mentioned read-up on the process at goodparts website.
 
looks like it might be a sweet set up except I have an 8 and do not know how that would match up. Besides around here anything with infinity on is big bucks. They have a body shop that has an open deal for all Infinaty wrecks. They repair them and ship them to PGH for resale.
 
The Quaife is a nice set-up. They are pricey with about a $1500 buy in for the TR8/Rover SD1 unit. On top of that, you will have to pay to have it installed. Last time I looked, I think they were being sold by a company out of Texas. Another alternative might be to go to a ford 8.0 or 8.8 rear end. Woody sells them, but the guy who makes them up for him isn't very reliable. Sometimes it takes months to get them back. The down fall is that they are heavier. The upside is that there are many different gear choices. They are a posi clutch type design. They are stronger, and you can get them with disc brakes. He takes a stock Ford rear end out of a t-bird tubo coupe or SVT mustang. He has them narrowed slightly, and has the correct TR mounts installed out of laser cut steel. He buys new shorter axles that have the correct bolt pattern. If you want to spend the extra money, he will even install a Willwood brake kit and a Locar e-brake set-up. The Fords come stock with rear disc that have a small drum in the center for drum style e-brake. The final price will be more than the Quaife install, but you will have a bullet proof rear end that will handle all the power you can make. You will also have to buy one of his custom driveshafts. They are an absolutely beautiful piece. They are modeled after one I had built years ago for my race car, and are not to be confused with the ones of lesser quality sold by a certain guy in Ohio. They are a Spicer unit with renewable u-joints. I have to run a stock rear in the race car, and I'm too cheap to pony up the money for one of Woody's rear ends for the street car. He has sold a couple of dozen over the years, and as fas as I know, everybody is happy with them. He has probably sold around 100 of the driveshafts. I think Tim Lanocha might make up a Chrysler rear end. I don't know if he sells them, but he has one in his car. You could look into having a local guy build one up for you. That would at least save on the shipping charges. I think the Ford rear ends can be found for around $350. I would bet you could do the rest for $1500 or so. Parts ain't cheap nomore.
 
I've got the Quaife in my car.. aside from the obvious benefits, I can't tell it from the stock diff. I bought mine from Moss UK. At the time (if I remember, I got it on a sale), to buy it from Moss and pay to have it shipped over was cheaper than sourcing it from the U.S. I had John Esposito of Quantumechanics fame. All in all, he charged me $650, to rebuild the diff and install the Quaife.

I can't say that I've been able to fully realize the full potential of the new diff yet. Shortly after installing the new diff, my main seal started leaking on the clutch with unfavorable results. However, I can definitely tell around the curvies though!!
 
I just did a little surfing and the best price I found in the U.S. was around $1240.00. I found a place in Britain that had them for 520 pounds. With todays exchange rate, that equates to $1005.00. I saw one on e-bay sell for $800 or so about 5 months ago. There is a guy selling a car here in Massachusetts that has a Quaife in it. For only $11,000 you can have the whole car with a Quaife all ready installed. It also comes with a 4.9 liter monster of a motor, Panasports, canvas top, and a whole list of other goodies. Just the car you need to go out and humble some Porche owners.
 
My Quaife has worked great-on the road and autocross. I installed it my self--not that hard and you can change your seals at the same time. https://www.autotech.com/prod_drive_diffs.htm is where I bought mine--nine years ago they had the best price and it looks like they still have good prices. At the time they gave me a discount when I mentioned a competitors price. The Triumph diffs are not listed in their web site you will have to call.
 
Have you considered, or has anyone done a Detroit Tru-Trac style diff. Slightly different than the Quaiffe, but gear centercore instead of clutch like the Salisbury.

Thinking about exploring that with my 75, when I get around to it. Would like to hear if anyone else has trie it yet.
