To all, I was wondering if there is anyone out there who has an ur-q with a modified Torsen Diff. I have noticed in the QCUSA Newsletter that there was one ur-q, I think it was an 83, with the mods done. I was wondering how difficult and how much it is? I plan on doing some mods, albeit not right away, and that sounds like an interesting one. later Angelo A 83 Ur-q------e.t.a. 15 days 86 Coupe Gt
