"Understeer is when you hit the wall with the front of the car and oversteer is when you hit the wall with the rear of the car.
Horsepower is how fast you hit the wall, torque is how far you take the wall with you."
Sorry I thought the 240 could not run the late 5 speeds (oh yeah your not in a 240 duh! my bad)But seriously have you looked into that? The truck rear diffs are plentful and cheap. I heard that the OD box set likes the taller gearing and they are also a lot easier/cheaper to get. Sam N said somthing to me about that last year as an alternative to trying to fix/replace the comp boxes (and trick parts are available if you want to tweak/rebuild one).
I think this is what Don Ahrens did with his car (not IT but very close in the drive train)

Id num for trucks is on panel in eng compartment.
ca41 r180 4.11, ca43 4.375 ca46 4.625 look for 720s 80-83
86+ hardbodies and 720s (4.11 or 4.625) also some of the frontiers had ca45 (4.54) 2003+ , started changing to r200s mid 80s so look for 4 bagers, and yes will be on 4x4 front diff only. The 4.44 can be found on some of the subies (dont know which)
I got this off the nissan-infiniti forum dont remember where old post.
Ron, I did stumble across this price on an LSD unit, but I'm not sure whether it will be correct for your ring gear diameter.

I know you started off by saying you don't like gear types, but any way, look at OBX differentials. I don't know if they make something for the R180, but I did meet a guy who described having one in his 240, but not being a racecar it might have been an R200.
The 1987 1/2 to 1989 300zx turbos had a clutch LSD w/ a 3:74. 88 and 89 non turbo's got a 3:90 open. Both in the R200. The 3:74 clutch types tend to bring about $500 on the used market from what I've seen (and paid).
What is your aversion to the gear types?
So Keith, what's the hot tip? And from what I remember Chet said he ran a 4:11 and it was hell on the valve train.
