Limited slip R200

[grannyknot]

I been going though the archives of this subject and for me at least it's a dizzying array options and requirements.

I have a longnose R200 open diff 3.90:1 with ujoint half shafts that works perfectly but would like limited slip capabilities.

 

Is there a clutch type or viscus type closed gear set that I can install in my existing housing?

Thanks,

Chris

Don't do any thing until John Coffey replies to this thread

Ha!  OS Giken Super Lock part number NS046HA.

Eh... John, On the website they say: For fairladyZ 240Z: NS081-HA (R180 type 115mm ring gear ID)

 

I think you have worked with it?  So there are more ways to come to a good limited slip diff?

 

 

FWIW..

That's for the R180.  The OP above asked about a unit for the R200.  And yes, you can buy new from Quiaffe in the UK, an OBX from China, or find a used Nismo, Nissan Competition, or Powerbrute unit somehwere.

John, thanks for that part #, looks like just the thing.

But while were on the topic, I would be interested in your opinion on the OBX unit with the rbryant washer and bolt upgrade kit.

I've read a couple of things that imply that with the better washers it is a decent unit at 1/4 the price.

Thanks,

Chris

I'm not interested in a part that I have to disassemble and fix right out of the box.  I personally would not waste my time and money on one.

John, does OBX build them that way (wrong) to get around a patent?  It seems like a good unit once put together the right way.

I don't know.
