JohnUKVetteNut Posted February 18, 2012 Share Posted February 18, 2012 Hi Folks My 2005 auto/roadster is 4 weeks old to me and have been trying to find out wether its got an LSD or not? I did email Nissan japan with vin number and they checked and said yes!! I did get off the internet a "nissan workshopmanual" cd and reading through it appears to say all auto's had lsd and manuals were optional lsd's in 2005 anyway! The lsd is the low effective viscous type not a plate type. Just thought i would pass that on JohnUKVetteNut Quote Link to comment Share on other sites More sharing options...

Dblock Posted February 19, 2012 Share Posted February 19, 2012 If your car is standard but comes with a LSD it's going to be a vlsd unless someone has changed it? Quote Link to comment Share on other sites More sharing options...

evilscorp Posted February 19, 2012 Share Posted February 19, 2012 I believe not all JDM's got the viscous diff as when I went to service mine I noticed mine was different and I think ZMANALEX told me mine was a mechanical one? Quote Link to comment Share on other sites More sharing options...
evilscorp Posted February 19, 2012 Share Posted February 19, 2012 Its a hypoy type diff just re-read my PM's Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted February 19, 2012 Share Posted February 19, 2012 Its a hypoy type diff just re-read my PM's Yours is a non VLSD and therefore took the hypoy type oil. The VLSD fluid is specialised and not suitable for your non VLSD. Normally the diffs are easily identified as the VLSD have the coolant fins on the pumpkin. Remember now?

No mate, Hypoy is a "type" of oil that goes into "normal" diffs. As regards the differences between normal diffs, LSDs and VLSDs then I am afraid that you are going to have a Google mate.

andlid Posted February 20, 2012 Share Posted February 20, 2012 brings back memories when i was told that I had a non-vlsd diff... turned out I had a VLSD afterall even though I did not have the fins on the case. Best way to test it is actually to test it! (or open it) I found out the hardway by opening the diff and see that my new LSD wouldn't fit Quote Link to comment Share on other sites More sharing options...
docwra Posted February 20, 2012 Share Posted February 20, 2012 Eh? You get some JDM's with an open diff? What a rip! Quote Link to comment Share on other sites More sharing options...

andlid Posted February 20, 2012 Share Posted February 20, 2012 Yeah if its a base one. Its not clear from most things people tell you. Best bet is to test it...... Quote Link to comment Share on other sites More sharing options...

andlid Posted February 20, 2012 Share Posted February 20, 2012 Track spec? Aftermarket then maybe? Stick one tyre on gravel and other on tarmac? Dont know since its vlsd that sticking it on stands would work. Burnout? Quote Link to comment Share on other sites More sharing options...
docwra Posted February 20, 2012 Share Posted February 20, 2012 Best and easiest way is just to boot it out of a turning - if one wheel spins its open, if the back end of the car comes round its LSD. Open diffs can still leave two black lines, LSD's when knackered dont always turn the other wheel If it was mechanical youd know about it by now too, mainly from the clonking Quote Link to comment Share on other sites More sharing options...
evilscorp Posted February 20, 2012 Share Posted February 20, 2012 I havent changed the diff oil yet just asked alex ages ago about it. You can still get the back end of a rwd car out even if it dosent have a lsd. Mine is very easy to get the rear hanging out as all the boot plastics are gone.(some weight in it all).

Mine is very easy to get the rear hanging out as all the boot plastics are gone.(some weight in it all). Not from a standing start you cant, and even when you are moving your "drift" will turn into a "one wheel burnout" soon enough. Removal of boot plastics doesnt make a lot of difference to driftiness, trust me Quote Link to comment Share on other sites More sharing options...
evilscorp Posted February 21, 2012 Share Posted February 21, 2012 Had the car up on the trolley jack, turned one wheel the other didnt move then just to make sure tried moving the other one. forgot it was wet when I last used him and the brembos had seized. After moving him back and forth, jacked its fat ass in the air again and to my delight both wheels turn in the same direction when you move only one so I've got a LSD, I presume its the viscous type just without the optional NISMO cooling fins that UK models get as standard.
