Looking at grabbing a LSD from a 6 speed V35. 

Having trouble finding information confirming that it's a direct fit to the 3.5 RWD Stagea. 

Different forums mention things about splines not lining up and ratios being different...

I am aware the LSD's from ARX etc will fit easy, but I have the opportunity to get a cheap V35 diff.

 

Thanks!

They are both R200 diffs, from similar era cars, so it is likely that the housings/mountings etc are compatible.

Splines not lining up is not a problem unless the LSD has different stub axles to what the other diff has.  This is actually a strong possibility.  So if you have to keep the stub axles that belong to the centre, then you may have to look at swapping driveshafts too.  This is possible.  Most (OK, not necessarily most, but certainly many) Nissan driveshafts swap from family to family.

Ratio difference is something that you will have to work out if the change is good or bad.  It will throw your speedo out.  That's always bad.  If you can't take it, then you will be looking at swapping the CW&P from your original diff onto the LSD centre.  This is a complete disassemble of both diffs and reassembly (and proper setup) of at least one.  This is usually possible, but Nissan do have a habit of launching surprises at the unwary, where the CW bolts are different sizes in two otherwise similar diffs.

The other problem that may crop up is differences in the ABS sensors and rings.

Thankfully my engine is stock, so a VLSD will work just fine. Just as they do in the AWD Stageas, 350z and V35 cars already. I used to run a tiny stock Mazda VLSD in my 260hp MX5 NA with zero troubles, so not sure what level of power you are talking about

If youre going to the trouble of swapping diffs, its worth getting something half decent. Especially if you dont knkw if its a 100% fit.
I upgraded to NM35 helical diff for my mechanically stock car and very happy with that choice. Due to the immense variety of R200 diffs, you just dont really know until you go to put it in.

Don't be a f**kwit.  You asked.  I answered with useful info.  I also told you that if it was a VLSD it was a waste of time, not knowing whether Nissan persisted with putting those useless lumps of shit into cars after the R3x era.  Now that I do know, I can authoritatively tell the next guy that it is definitely a bad idea.  Thanks, you have helped the forum.

Put it this way, if you have a car that will work well with a VLSD, you don't really need an LSD at all.

The issue I'm concerned about is ratios and fitment, not what type of lsd i should be using.

and like I said, with fitment you won't really know until you go to put it in. Unless the info is on SAU or a Canadian/UK Skyline forum, you probably won't find the information via google.

The Y34 has almost identical rear end to M35/V35/Z33, all using R200 diff. I think all used 6x1 bolt half-shafts with external ABS rings on the half shafts. and NM35 helical diff needed a fair chunk of one of my half shafts machined off to fit it. The diff, fitting and machining was a bit over $500 total, which is considered a decent total price for a helical diff.
My point is, how much do you plan to save trying to use V35 diff? the cost could potentially be much higher than just sourcing something that others have proven to fit without issue.

The only options I've heard are aftermarket and cost out the arse. If I can get anything that is not an open diff, second hand on the cheap, then sign me up!

I agree you will never know for certain until you fit the diff yourself, that's why I'm asking on a forum for first hand experience. 

I see second hand diffs going for $150-250 online, so not sure why everyone is scolding me for wanting to throw in a dirt cheap replacement for a stock standard car with a shitty open diff. It's a great idea I think! 

Try and get an OEM helical diff from a M35 or whatever LSD the 350Z track edition runs (unless its viscous, then avoid) and get a decent mechanic or diff specialist to fit it.

Youre right, aftermarket diffs are not worth the price for basic setups.

 

I tried an R34 R200 helical diff but the dimensions of the diff centres seemed completely different.

    • Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents
    • I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.
    • One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
    • I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.  
    • Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.
