Is this an S-Chassis Differential??? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Luvs2slide · 03-18-2010, 04:55 AM

Picked this up locally in Japan. Was "told" it came from a 180. But the output shafts looks like they're bolted in and the backplate looked narrower. Also has a part number on the top...looked it up but found nothin. Looks like a S14 housing b/c of the large two mounting holes and the two studs on the backplate. Don't know if I'm trippin or what. Please help!

diehappydrifter · 03-18-2010, 04:59 AM

it looks to be a s14 with the bolts and large holes but i am with you on the output shafts...i havent seen any that bolted up....maybe something special...lol

ZX88 · 03-18-2010, 07:48 AM

looks like s13 axles. you can run an s14 diff in a s13 the differences are the axel bolts.

g6civcx · 03-18-2010, 08:37 AM

If it's really an R200 you can use it. Just change the rear cover to an S13.

If you need custom axles and driveshaft flanges to fit call the Drive Shaft Shop.

S13 and S14 axles are the same bolt pattern and use the same bolts. The earlier S13s with the CA18 were the 5bolt type, all others are 6bolt as shown.

Prez · 03-18-2010, 02:39 PM

he's saying the output is bolted into housing... never saw it but its a S14 diff regardless and it will fit regardless on output shafts no matter how they are attached... its a s14 cause it requires bushing on back two mounts.... swap cover for use in a s13 and you'll have to get some adapters or mounts(solid are good) to fill the hole... s13's utilize just a bolt no bushings...

edit: after looking at it again is it me or the pic or w/e but does the entire housing look skinny? like a s chassis diff with a eating disorder?

Slidin240Wayz · 03-18-2010, 03:06 PM

i've never seen that setup before.

maybe its not from a 180 and could be alot more trouble than necessary to make work.

Luvs2slide · 03-18-2010, 07:44 PM

Thats just it. It may have came from a 180sx with a CA18 in it. The other thing I noticed was how skinny the back plate is. Its kind of hard to tell from the pic but it looks alot narrower in person. Also as someone said above, the output shafts look like they are bolted in. I ran 32 diff (R200 I think) and this looks a lot different... Anyone else have any other suggestions?

g6civcx · 03-18-2010, 08:31 PM

Just try to bolt the entire pumpkin into the subframe. If it fits, you can get propeller and drive shafts built to fit the diff.

yokotavia · 03-18-2010, 10:00 PM

That is a non turbo diff. They are smaller and the pumpkins are different.

Sileighty_85 · 03-18-2010, 10:56 PM

Couldnt find in on FAST, Closest POart number i could find was a Laural P/N 38311-20E10

Dont think thats a S-Chassis Diff.

Defiantly not a 180SX seeing that 180SX (like 240's) use 4 bolt Covers

Not S14 either

Looks like an Older Model Diff

I know ive seen that diff somewhere before

No shit? I was under the impression that N/A & turbo 180sx all had the same diff of course minus VLSD.

I really don't want to go through the trouble of pulling mine out and try to fit this one if I don't know for sure it will fit. I would rather know ahead of time if it will or not. Mainly trying to determine what the fuck this diff is from. I find it hard to believe that the part numbers on top are wrong...But fuck, maybe this shit was made on a monday/friday lol

racepar1 · 03-19-2010, 03:00 AM

I have never seen an s-chasis diff that looked like that before. I don't think it's an s-chasis diff at all. It MIGHT not even be an r200, it looks an r180. Is it smaller then a normal s-chasis diff? I seem to remember hearing somewhere that some of the EARLY CA18 cars came with r180's in them, but I am not anywhere even close to certain on that one.

D.Adams · 03-19-2010, 03:12 AM

open it up .... see if it s a open diff or a VLSD

Luvs2slide · 03-19-2010, 04:01 AM

If it came out of a CA18 180sx, wouldn't it have the smaller two bolt holes in front??? I mean the backplate looks like it may have been swapped...but for some reason I keep thinking this thing looks like a S14 housing.

It looks closes although the part numbers dont match for the CA S13 i got 38311-10F00

the front mounting of the pumkin is different also, Usually Nissan is pretty accurate on the IPB's So i dont know

Also the part number(38311-10F00) matched to the early S13, Cefiro's, Laurals, and it say the R32 Skyline with the RB20E.

Luvs2slide · 03-19-2010, 10:30 AM

So that diagram above is from a CA 180sx?

Not sure, Its Just says S13 so its either the Silvia or the 180SX
Although S13 Silvia's and 180SX are exactly the same minus the Body back half.

The subframes are the same also

who did you buy the diff from?

dkenn81 · 03-19-2010, 04:44 PM

it uses the same output shafts but doesnt seem to be a 180sx/s chassis diff.

yokotavia · 03-19-2010, 05:54 PM

me and some friends had a nismo 2way in our NA s13 missile. it was na sr and it came with a 2 way. the pumpkin looked like that.

and ive never seen any turbo cars have that. only NA

NA c33 laurels have them too.

yokotavia · 03-19-2010, 05:54 PM

not saying your shit is 2way. it is probably an open diff.

we bought our car and it had a 2way installed from the previous owner

Luvs2slide · 03-19-2010, 07:48 PM

Hmm...Yokota, so do you think this would fit a turbo 180sx? I'm not sure of the differences between the turbo/NA stuff here in Japan as far as differential go. But I do know that my car (turbo) came with 5 bolt axels and VLSD. Thats for all the help guys, I really appreciate it.

yokotavia · 03-20-2010, 12:00 AM

why would you want to put this in a turbo car?

a vlsd is better than that NA open diff in that first post.

buy a real diff broski.

and NA diffs are r180 im sure, which arent as strong as r200's

drift freaq · 03-20-2010, 01:14 AM

It does look like a R180, from the 80's that someone possibly did an output shaft swap on.

A lot of 240Z owners do that to upgrade from a open diff to a clutch pack diff. except the Z car guys would put in a long nose one.

R200's have been being used in several different forms since the early 80's. Long nose ,short nose, different types of output shafts, same pretty much goes for the R180's from the 70's into the 80's, internal specs were always basically the same(except long pinions on long cases) just different cases and output shafts for mounting into different cars. . Oh and Suburu still uses R160's in their cars. LOL talk about a tiny diff. Those came on 510's and boy were they small.

At the moment I have a 1.5 way...I think. I was told its a 2 way but it doesnt seem to lock on Decel. My plan was to install this weird looking one temporarily until I can open up the current diff and see what kind it is and maybe to see the wear/tear.

But to everyone else, thanks for the help. Hopefully this will help out someone else in the future as well.

HYPNOTIK · 03-24-2010, 04:17 PM

I can't see your pictures at work but you probly have a R180 diff. NA 13's and 14's came with the R180, that's why I had to swap subframes to run an R200.

!Zar! · 03-24-2010, 04:40 PM

I never knew this stuff.

I've been educated!

yokotavia · 03-24-2010, 07:57 PM

yeah both japanese NONTURBO s13s and s14s came with a r180

in order to put a r200 diff into a s14 that is originally nonturbo you have to swap the subframes because the rear diff mounting bolts are closer together

and when you swap an r200 diff into an s13 you do nothing, there are an extra set of holes in the subframe for the wider r200 studs

boom

HYPNOTIK · 03-25-2010, 06:12 PM

An easy way to tell the difference besides the obvious size difference is that the mounting bolts on the R200 are ~4.5" apart and on the R180 they are ~3-3.5" apart.

This doesn't apply to you stateside guys, I think all usdm s-chassis came with R200's but I've never owned one in the states so I don't know for sure.

Luvs2slide · 03-26-2010, 02:33 AM

Damn thank for the clarification Casey & Yokota, Never knew the N/A cars came equipped with the R180s.
