R200 LSd Q's

[drunkenmaster]

Im looking at picking up a 3.7 R200 from a wrecker and perhaps getting some extra plates put in to increase the break away torque.

Any comments from the pros in regards to this?

Also are there any issues with fitting the LSD to the standard 260Z shafts?

Thanks

Not an expert on the lsd, but if youy shimmed it out too much it would cause more than normal wear and tear on the diffy. I think the factory break-away torque is set to 42 ft lbs.

As far as the 260 axel shafts, do you have the r-180 or r-200 rearend?

I have an R200, but i am hearing different R200 LSD's from different cars accept different splines etc etc

interested to hear anyone who has done this conversion re latter r 200 diff into 240 or 260 cars hear all different stories about ok if you use r200 diff output shafts to earlier axles and some that you can modify cv axles to suit

anyone done this please tell

I had the clutches in my Skyline's R200 replaced (the tolerances are very fine) & it's been shimmed up to 90ft/lbs breakaway. Any more than that (another 3 thousandths) and it was locked.

(this diff was completely open when I got the car)

My Z diff is set at 65ft/lbs with the original clutches just reversed.

Get someone who knows clutch-type LSD's to build it for you.

The OEM setting of ~45ft/lbs is too loose for a high-power performance application.

I have found a knowledgable guy to help me build the internals, i am more curious about fitment of suitable shafts now.

Since we have been referring to clutch plates (rather than a viscous centre), it's all too easy.

If your 260Z is already equipped with an R200, then all you will have to do is change over the tailshaft flange & bolt it in (the flange controls pinion-height so it has to be torqued correctly).

If you have an R180 equipped 260Z, then you wil need all the mounting gear from a car that already has an R200.

anybody gone the next step and fitted late R200 with cv jointed axles

If so how hard is it

for a kit which appears to do the trick.

so i will ask the question did we get 280zxt in australia to get the half shafts from or do we need to get these from the states too

Check the 2+2 280zx cars. In the states the 2+2 came with cv axles starting in 82 I think. Wish I could be of more help, but I don't know the differences in different countries.
