Installing Lsd On N/a R33

[HungarySkyline]

I was watching the drifting going on at Eastern creek last night , and i saw a r33 skyline non turbo drifting he did have alot of trouble with his single spinner, but towards the end he got alot better, he also stock suspension by the looks of it.

I was thinking about throwing on some coil overs and a turbo r33 lsd heard the gear ratios were the same.

Anyone ever installed the GTST LSD on a n/a? does it handle alot better?

The ratios are different, the GTST diff has a longer ratio.

Also the stock diff if a viscous diff which pretty much all of them are worn out and will just single peg all day long. you could shim it to lock it a bit more. there is a thread in the DIY section about it people have had good results

[HungarySkyline]

Okay mad, yeah guess ill just have to shim mine then.

thanks

What car are you planning to do this with?

If you have a 33 ratios are the same for NA or turbo but it depends on if you get an auto or manual diff.

If you're planning it for a 31 which is the only car you have listed then it's a lot more involved.

If Jap Spec IRS They run an R200 Longnose diff which isn't just a simple swap. You'd probably need to do the whole subframe etc with custom mounts, custom tailshaft etc.

If Aus spec live axle you will need to do the same as the Aus specs run a Borg Warner diff which is entirely different. Kaaz offer an LSD centre for these diffs or you could use a cone type LSD out of a Sillhouette though I don't think they are particularly strong.

Haha i just edited that part of my profile as you were posting, Yeah i have a r33 non turbo. i think the auto diffs have a 4.3 something ratio, which is higher then the manual ones.

Yep autos are 4:3, manuals 4:1

If your car already has an LSD shimming it is your cheapest option. If it's a single spinner then you'll need to source an LSD centre and probably shim it.

If you post your VIN in the VINS you want fasted thread in General automotive discussion it'll tell you if your car is a GTS25/S which will have an LSD or just a normal natro which won't.

Yeah i just jacked up the car its got an lsd. I will have to get it shimmed, and probably some coil overs if im going to start drifting(in the wet for now lol)

You can fit an R33 GTS-t LSD onto an R33 GTS by fitting S15 driveshafts

I just welded my tho and it does the job

hey everyone. rather than starting my own thread and asking the same thing. i have a 1995 r33 gts25 and im wondering if i have an lsd... im going to jack the car up (rear) in a minute and give it a rev but is this definate... cause what if its warn and only one spins? how much does shimming a diff cost?

[mad082]

The car will probably turn both wheels, with or without a lsd. But if you put the car in neutral, hand brake off and turn one of the wheels by hand. If they both turn the same way, you have a lsd

I also have a R33 S1 and well looks like there are a few of us that are in the same boat. Now which do you guys think is best? shim or just solid weld the diff? Why do you prefer the weld or the shim? and what prices would one expect to pay to get the diff welded or shimed? I do not know much about a diff except how it operates. Any advice would help

[Captain Natro]

Shimming costs more and retains some form of LSD depending how "tight" you go. Welding it is as simple as well welding the spider gears lol.

Get a mate that's handy with a welder and give him a bottle of spirits (as payment), down side is its illegal and very easy to see/hear on the street.

Shim it, takes sfa time and at the end of the day you've still got a non f**ked diff.
