Recommendation for a skyline diff into an S2000?

[9krpm]

As some of you are awared, I've been lurking on this forum because I love the skylines......and you guys too :headspin: I hope you guys don't mind

I don't have a skyline and love to get a GTR down the track. I actually own a s2000. :wassup: The S2000 parts are pissy weak compare to your skylines. My engine is being rebuilt atm. My next weakest link will be the differential. The S2000 has a torsen diff and an aluminium casing. Most s2k with a little bit extra power tend to crack the diff housing clean.

I've been thinking about mechanical diff, silvia cusco/kaaz diff or a skyline diff.

All of the diffs will need custom fitting for the s2k as there is none strenthened s2k diff available in Japan.

What would you guys recommend for a strong, lighweight and inexpensive complete differential?

[Steve]

Go the mechanical. I have a nismo, which is pretty street friendly, it doesnt seem anywhere as clunky or harsh as Kaaz or Cusco, quite nice.

If you want a stock skyline diff, I have a spare one for sale:p

[9krpm]

how much for a mechanical and how much will you sell you diff for steve?

which model is your diff?

is the mechanical any lighter than the oem skyline diff?

Thanks for the info

Hey dan ive also got a 32gtr rear diff i can sell you for a good price, not sure on specs sure someone will be able to help out

[Steve]

dont think the mech diff is lighter? not sure, they are both not very light items.

New mech diff is around the 2K mark, second hand, depends on if you get lucky or not, but reasonable price is between 800-1.2k for good condition from what I have seen.

Not sure what a stock diff is worth - make me an offer:)

[9krpm]

sorry for another amateur questions

could someone kindly explain the differences in the differential betweent a gtr vs gts and r32 vs r33? (I don't think it will be economical for a r34 diff )

how easy is it to blow a diff for you guys eg what kind of power output will blow a for example gts diff?

[9krpm]

is the mech diff a lot stronger steve?

[EnricoPalazzo]

gts diff wont blow, but it will open wheel as its a viscous type.

A mech diff is not viscous, it is Mechanical inside so basically is alot stronger. for ur type of driving, a 1.5way mech diff is what u want. This is made for circuit racing aswell as daily driving etc.

Check out the s2k forum as they would know alot more then us about puttin a better diff into ur car aswell as what types are available.

Have you still considered getting the stock diff nitrided or cyrogenically treated instead? I think it might be worth doing before you put a nonS2000 diff in.

[EnricoPalazzo]

Well i was bored so i did some researchin for u.

There are a number of beefed up diffs made for s2k. Mugen, Kaaz, Cusco ATS

everything you ever wanted to know about mechanical diffs. If you want to get into a bit of dorifto, go the two way. If you dont want to get into a bit of dorifto, go the two way:)

If you can source a 1.5 way that is fine too I suppose, I have a two way - very predictable, and if you get sideways and back off too quickly, you dont have to worry about the rear end swinging to the other side of the road, it just gently pulls back in.

Just be warned, they can go clunk alot, and make alot of noise in service stations and car parks when the wheels lock and you are turning corners at slow speeds.

Hahah

[9krpm]

thanks for the links dan

I've been a member of that forum for the past 2+ years

I would say that I knew most things about the s2k diff and it's aftermarkets. It's the first weakest link in our drivetrain you know. It did not take long for "Phoenix" to break 2 diffs with his stock/near stock power :throwup:

Sad to report that the strongest way of strengthening the s2k diff thus far is a set of kaaz/cusco lsd, J's 4.44 crown+ pinion (which I have), comptech reinforced diff housing and drop most of these stuffs in a cryogenic tub. Unfortunately some owners have reported failure with only mod power output (300hp). I am afraid that this combination won't be any good for me.....prob around 300rwk if it ever finish

Thanks for the links and excellent points steve......I think I will go with a 1.5 way for hill/track run rather than drifting.

busky2k, the only place that does it is in sydney. It's too heavy to send most of the diff up there and it prob won't last any way.

Thanks for all the informative responses guys

So is there any difference between the gtr and gts rear diff?

Is there any difference in r32 vs r33 rear diff?

[Steve]

R33GTSt - 4.11:1, R32GTSt - 4.3#:1

not sure about the GTR, as it had a larger engine.

If I had to choose, I would say go the R32 GTS diff, its shorter = more torque:)

BTW, D1 garage had (think they still have it) a TRD diff centre, dont know if its any good to you.

[EnricoPalazzo]

I think ur lookin at trouble puttin a differnt diff into ur s2k homie. to much customizing.

[Busky2k]

9krpm, Im pretty sure there is a place here in SA that did it. I'll dig up the magazine article for you.

[9krpm]

I think ur lookin at trouble puttin a differnt diff into ur s2k homie. to much customizing.

if I don't look for something new I will have to be very gentle with my car

It's no fun having enough power to embarass some V8 and do rolling start with every drag

Given that most of you guys claim to go through Maccas in under 10sec on the other thread :wassup: I figure that I will need to adopt some skylines parts to hang around with the best

Is there much difference between the viscous oem diff and the 1.5 mechanical diff in term of driving dan?
