(theoretically) a torsen rear diff from a 2010+ IS-F would fit the 06+ IS350, right?
Correct, but you'd just use the Torsen and put it into your existing case, as the IS F has a different case and subframe bushings, plus the gearing in the IS F is 2.9:1 versus the 4.1:1 in the IS350. You would not want IS F gearing in an IS350.

True! So if that's the case could the ring gear easily be transferred from the 350 to the 2010+ Torsen LSD? I assume the half shaft inputs (spline count) are the same as that of the 350?
Heya Jeff Lange, isn't that the same Spec as the MKIII Supra diff? It sure looks like one to me. Lots of IS300 guys are trying to get Supra Diffs off me to stuff in the IS300.
I'd be surprised if you could do it for less than just buying an aftermarket posi though.
Isn't a new IS-F diff north of 4 grand? (it's not like you'll find a bunch sitting in scrap yards given how relatively few Fs are sold at all)
But of course. But when say 5 yrs down the road this might be helpful to someone. If anything, I'd probably go with another Quaife. Had good experience with the one I had in my Honda with 400+ whp.
Yes, but remember that the MK3 Supra diffs are clutch type and 20 years (at least) old, they're probably quite worn by now, so you'd likely want to overhaul it before installing it.
