the 1 that locked?
it was fine n dandy, i dint think it was lsd as it dint really feel that positive thru the bends but when i took it our it was a propper lsd box, never felt like the clutch was gone tho, i just came out a mc'd's a bit lairy and hit a pot hole, thought the cv was hanging on for the journey but it was actually mullered and the drivers side shaft got us home (pulling left like a mofo tho on acceleration)
the box i just put in was a reconned xr2 box (had it to hand so bunged it in

)
that was slipping bad but the boost is down to 10 and sometimes maybe 15 now
but thats 20 psi thru a std cutch for ya
