Diy:diff Shimming For R33 Gtst


Trust33

Recommended Posts

Defiantly worth the effort. Both wheels lock well under power. Can boost it rite up in tight corners and also both compression lock up under braking and the car remains straight. Feels much, much better then the 2-way LSD in the Passage. When it does let go in a power slide the control is incredible compared to before. A recomended mod for anyone.

Where are you located? Would you do the job for others as I don't have the appropriate tools and my car always one legs and pulls to one side. Obviously some moola will be given. Can post the internals so you don't have to take the entire diff.

Its a very time consuming process and time is something I don't have at the moment. Probably give me a month and PM me and it might be possible. Between this car and work there's nothing left. Sorry.:(

On another note I hit a realy tight corner yesterday going way too fast and got a chirp from the inside wheel so its defiantly working well.

Are the part no. For the shims the same for a r32 diff?

Cheers- trent

Yes, I used the part numbers in this thread to buy shims for my 32gtst diff.

saved our ass here in the UAE =) doing it now.

fitted em up, what a bitch to get the center back into the car lol. when i finaly got it in, the splines on the longer half shaft didnt line up in the final section. what a bitch, back out with the center it came, i did actualy line up the splines like you said, might i add for anyone else doing this. once you put ur shims in put both half shafts into the center completly in, then tighten the 2 philips heads, then leave the shafts in. put ur ring gear over the top and rattle that up with the half shafts still in the center. makes it alot easier and no room for error. the first time i was literaly .2mm off the splines being 100percent. and yet it wouldnt go in all together.... peace!

Any chance of getting the pics working again really want to give this a go. So say about 3mm would be good for drifting or should i go more like 3.4?

Pretty much depends how screwed your diff is, it'll basically either be almost completely locked or it'll skip around corners and open up under power (worst of both worlds), or it'll be the same.

So just go the biggest you can get in there if you want to lock it, if you want it to be like an LSD just get an LSD.

I used 2x 1.49mm shims (one on either side), it was pretty well locked to begin with but after a couple of weeks it had worn in nicely and is now just like a new LSD.

My local Nissan had them in stock.. did they say they were ex-east? or ex-japan?

3 weeks sounds about right from Japland, everything I've gotten that was ex-east gets sent in an overnight bag so I have it within a couple of days (case in point, ordered a brake booster 1-way valve on Saturday that was ex-east and it arrived yesterday).

just got around to putting mine in,both sides have a shim or 2 with 3 in total so i've got more then 3.6+ mm in there nearing 4 id say (will need to double check invoice to confirm).

so question is how long does it take to bed/ wear in as in getting some shuddering under hard cornering ?

Hello!

I have heard that you can´t shim up a GTST Diff for it´s a viscodiff and not a lsd diff, the shims may take all the power from the diff and the viscodifferential will break? That a shimmed diff will not work in the long run? Is this bullshit or true?

Many people seem very happy with their but boring if it would break!?

sorry for my bad English, I am Swedish pirate.gifaction-smiley-069.gif

    • Dear all I hope you guys can help me before i'll throw this Car away. My Power Steering Belt slipped for the third time (one time completely and now the second time "only" half way and straight into the Cooler Fan which made a lovely Sound midway my Trip). I'll bring it to my mechanic to look into this (propably the Car is just cursed and hates me) but i need to drive it to him which takes me a 3 hours drive. The last time a guy from the breakdown service fixed it by relaxing and tightening the belt again, which i tried too, but i've loosen the Bolts according to the DIY FAQ and the P/S Pump won't move at all to loosen the Belt. I've tried pushing, pulling, leverage and even a hammer out of frustration, but the Belt stays tight as is. Can anyone point me in the direction why this Car can't just be easy to work on once?
