Re: Torsen Differential for 2WD S70 T5M ??? (rothe)
The only cars I know of that use Torsen are Audi in their AWD cars. I know there are some limited slip diffs you can get for the car. I think Heico Sportiv makes them, so you could probably order one through IPD.
Actually, Mazda has been using Torsens in RX-7s and Miatas for years. I even dropped a Miata Torsen into my '85 RX-7 when my original LSD clutches gave up. Even Honda's Acura CL Type S now has one. They refer to it as a Helical limited slip differential.<p>Perhaps I should have worded the original question a little bit differently, though. I'm looking for a non-viscous and non-clutch-type limited slip differential, similar to either a Torsen or Quaife unit which uses gears to sense wheel slippage and redirect torque to the non-slipping wheel. The advantage is that there are no clutches to wear out, as my old RX-7 did from too many years of autocrossing, and the diff responds better to slippage than the viscous type units used for all-weather, non-performance applications.<p>What kind of limited slip diff do the 850 and 70-series R-version cars have in them? Anybody have any idea if they can be dropped into a US-spec T5M, and what's involved? I'm not thinking to jump on this project right away, but it might be something that I'd do when the clutch goes south someday.<p>BTW, anybody who's not familiar with these types of differentials and is interested in learning more about them would do well to visit:<p><A HREF="http://www.howstuffworks.com/differential.htm" TARGET="_blank">http://www.howstuffworks.com/differential.htm</A><p><BR><BR>
