WooHooo! 4.11 R200 Torsen unit!

[Phred]

Hi Team,

I'm building a 71Z as a Vintage SCCA car. I have been reading all the comments on the Quaife/Gleason/Torson units.

I have chosen to use the R-180 for the weight savings it offers.

I have a 3.9:1, however I need to pull it apart to measure the ring gear, as Quaife offers units in both 110mm, and 115mm ID.

Unless I can find a used one for sale, I'll be ordering one in a month or two. I"ll let you know how it goes.

Dave Rebello wants $600 to rebuild an R180 and install the Quaiffe!? Call these guys: http://www.gearedbyunitrax.com/main.html - Ask for Jerry.

They've built me three R180s - one with the Nissan Comp LSD and two with Quaifes. $300 including all new bearings and seals.

Sounds like a great deal. Rebello is a bit pricey but from what I know about their work it is top notch. Is it worth the money? Depends on who you ask, like everything else, there are differing opinions.

The only problem I see is by the time you buy a ring and pinion in whatever ratio you want and a Quaife or LSD you are talking about a big chunk of change in anyones book. I guess that is the price we pay to have our toys! The old saying goes, he who has the most wins!

to all of those whom are fortunate enuf to have the gleason-torsen units...be thankful. i know a number of racers who also have these units and swear by them. a few years ago, i went thru a friend of mine [35+ years senior engineer at gleason works here in rochester] and we searched for months to try to find a "leftover" unit [even contacted one of his coworkers in japan] with no luck. he then put me in touch with the senior engineer at zexel-torsen [zt/also here in rochester], i struck out there as well. i did speak to the r&d person about a group buy-but it seemed that we'd have to purchase 250+ units and then find a supplier who would b willing to 'guarantee' another 50 in sales per year, to absorb the tool up costs. zt still manufactures the units, gm, subaru, toyota, hummer, etc.-just not for our z cars.

this was of course prior to the resurgance in z popularity. i'd b happy to contact them to see if they make a unit for the z32, but i have no idea if the "guts" of a z32 diff would work in the r200 many of us are running. anyone know??

dreaming of finding that elusive torsen diff...

Sounds like you just may have the contacts to solve part of the mystery here.

I'm 95% sure the unit that is in my R-200 was from a Subaru. I know that some models of Subaru's did have the R-200 in them, but have never been able to track which ones it may have been that got the Torson unit from the factory. Perhaps with your contacts, you could find out by researching possible Subaru cars that came with the Torson, and then which ones came with the R-200 rear differential.

If it proves to be correct they may already have a Torson unit we can get to put in the R-200's, but I am quite certain there is not enough room in the R-180 case for the Torson unit.

i didn't think that subaru ever used anything larger than the r160. i haven't been able to look under a subaru svx [their last sports car with a 6 cyl] to see if that used the 160 or something larger. subaru also now makes the outback with a 6cyl and i believe that runs an r160 as well. i'm not sure though. anyone else??!

I have never seen anything bigger than an R160 in a Subaru. I am going to check around though and see what is in the Legacy's and the SVX. My interest is piqued.
