Also I would like to know what is needed to make a J30 LSD fit on my 92 240SX. I can't get any real answers because some say you need another differential cover and some say it's only the S14, and some say no mods at all it will fit right in. Can anyone clarify this for an s14?!?!?

This should answer your question about the J30 LSD.

I say buy a 95 J30 diff including yokes. You must have the yokes. Open up your stock diff and take out your stock yokes and through them away. Remove your open diff with the ring gear attached to it and remove the ring gear from the open diff. On the J30 diff remove the yokes and keep them. Remove the LSD diff with that high *** ring gear on it and take that off. Put your stock ring gear on the LSD diff and put it back into your stock pumpkin along with the LSD yokes. You have just built a R200V with no ABS and a 4.086 gear....

A J30 diff should not cost anymore than 200 bucks.

wow, so that will work and all I need is a 95+ j30 differential w/ yokes (what ARE yokes exactly?) and that's it because I use the stock pumpkin. Thanks.

I was reading up on the 300Z TT LSD, and it says that you have too switch the input bit? Is that the part that attaches too the driveshaft? or the yolks that attach too the driveshafts.

I'm quite interested in it with the 3.86 gears, my supra has 3.9 and its too short as it is for any kind of milage or top end. I can't imagine a 4.11, had that in my old Mk2 Supra, way too short for a highway car.

"i am personally a fan of the phantom grip!" thats because you havent driven a good LSD at the track yet. at 125 dollar peice cant repalce 900 dollars worth of clutch plates and engineering.

Either get one from a 180sx, a canadian 240sx, or though a company like phase 2, after-dark tuning, or enjuku-racing.-chet

Apples and oranges. transmission gearing ratios may be quite different between a Supra and a 240. I've felt what a J30 diff does to a stock KA. It makes it quite a dog in comparison to the stock gearing. A turbo car that has traction problems might benefit some from a taller rear gear though.

Exar-Kun: Yes, LS Auto gave me excellent customer service. When I called them to order my diff, Kevin was very helpful and explained the whole thing to me about the JDM axles and assured me that the gearing was also correct (I thought the jdm ones were 386's but not all are apparently) Anyway, I paid and Kevin shipped out the diff that day. The next day he called me up and told me that he had accidentally sent me two drivers side axles and he cross shipped a passenger side axle to me free of charge. I got the diff on a Thursday and the axle came in the next morning, so it was all good.

Overall, even with the mix up, I highly recommend them. Their response time to e-mail is quick, but their phone support is quicker and definitely top notch.

According to Don Nimi, this is a rumor that is quite untrue.

240sx1st 3.321:12nd 1.9:13rd 1.3:14th 1.00:15th 0.759:1

Mk3 Supra1st: 3.25:1 2nd: 1.96:1 3rd: 1.31:14th: 1.00:15th: 0.75:1

I turn about 3100 rpm at 120kph, 3600 at 140kph, its not good at all. If anyone can confirm RPM per speed on the 240 that would help! With 300hp I find my gears run out too early (especialyl with 6500rpm redline) for over 200kph my car is useless. I think that 4.11 rear end even with a higher 7500redline with an SR20 its gonna be too short with 260hp or so. I don't really care about 1/4 mile or road course so much. I need a good rear end for highway milage, I can't take 20mpg anymore.

Hopefully the J30 or Z32TT LSD will do the trick! Is the LSD on the TT's mechanical? While the stock S13 is Viscous I assume by the title of VLSD.

it is supposed to be 22 MPH x 1000rpm in 5th gear.

Far as I know the TT diffs are also Viscous.

I dont know maybe it is just a rumour? It made sense to me though since with the climate and snow, etc. An open diff is kinda useless, maybe not all canadian 240's but I'm sure a lot more here then in the states, I'm sure it was a big selling feature for the Nissan dealers

Question: Was LSD even offered in the states? Just curious

I am trying to select between two clutch-type LSDs: The Kaaz 1.5-way LSD and Nismo S.S.S. I understand that the SSS is much more user friendly when trying to adjust the breakaway torque but what other types of other differences are there? Thank you.

I believe the kaaz unit has more clutch packs(IE heavier duty), but Im not absolutely sure about it...-chet
