Any diff from an R32 or S13 will fit in your cefiro. But, there are a few different options.

There are 2 sizes of diffs the R180 and R200 (the diameters of the crownwheel).

R180s are smaller and obviously not as strong as R200. Also I don't think you can get an LSD R180 (unless it is aftermarket), so you want an R200.

The R200 comes in both viscous LSD and open wheel type. The LSDs have a sticker on them, but it's probably fallen off by now. The otherway to tell between an open diff and an LSD is that the output shafts will spin in opposite directions when you turn the input shaft of an open diff.

R200 also has 2 types of output shafts, either 5 bolt pattern or 6 bolt pattern.

You will need to check the bolt pattern of the output shafts on your cefiro and find a diff with the same bolt pattern to match, otherwise you'll have to swap your driveshafts as well.

As far as I know, all S13s use 6bolt output shafts, R32 use 5bolt output shafts, and LSDs were factory standard on turbo models.

That's a 180sx to the Aussies :)

I'd suggest you pop over to the for sale section on sxoc you'll probably find someone selling an S13 LSD there.

Hahah... no! S13 is a silvia... same running gear as the 180SX but it is still different car (body wise)

Like the 240SX is the 180SX for america

But like daisu said "same chassis/drivetrain. 180SX/200SX/240SX/silvia/s13

One's a PS13 and the other's an RPS13 I thought.

In any case he was refering to the UK 200SX up until mid-1994 was simply a 180SX only with a CA18DET rather than an SR20DET. They then switched to the S14 Silvia with the SR20DET but still sold it at the 200SX.

Here's a picture of my GF's old 200SX for clarification

Unfortunately none of the S13 models were delivered to australia, all of ours are imported JDM models so we name them as such.

180sx is the hatch with the popup headlights, and the silvia is the coupe with fixed headlights.

As for the PS13/RPS13, the P denotes SR20 powered, and the R denotes the 180sx liftback shape (pictured above).

Aha, so you'd call the 180SX an RS13 wheras since the UK never got the S13 Silvia we just call it an S13 anyway, and if someone has imported a Silvia, it's an "S13 Silvia"

In any case both cars have the same diffs, and the OP is looking for an S13 LSD :P

On a related note I'm still trying to figure out all the A31 chassis codes. So far I've got:

L = Facelift

N = 4WD (with R32 suspension rather than S13)

E = RB25DE??

Pre-1990 only:

R = DOHC engine??

C = ??

H = ??

GFE = ??

GAEP = ??

GFS = Turbo??

How do I tell the difference between a R32 R180 and R200 LSD ???

I need one to replace my damged diff in my cefiro A31. It already has an R32 rear end though. The car was purchased with this and other upgrades.

I was told that the R33 and 300zx Twin Turbo R230 LSD cannot work.

Anyone with any advice ????

R180 diffs have collars that bolt onto the outside of the housing around the halfshafts.

Use an R200 out of S13/180sx/R32/C33/A31. Just make sure that the new diff has the same number of bolts where the driveshafts and halfshafts meet. (6bolt or 5bolt)

Hi there! I have recently bought a Nissan Altima 1991 and confused about whether it already has an LSD diff or not? Is it a clutch LSD or not? If it is not an LSD how can I convert it to LSD without replacing the diff? Welding would work or not? Bcoz it is nearly impossible to find such diffs in my city. Need help please.

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
