As i suspected... the night i blew my turbo... i did my diff as well.

Didnt get to test it out till tonight (but at least the car goes well in general)

So, for an R31... with the R200 (think its a long nose)

What goes into it easily, and is tougher than what i had.

As i've never heard of an R31 Coupe blowing it's diff... but this one has.

And now im goin to have a fair whack more power too so i dont wanna be frying them every 6 months.

Would a 1.5 way LSD (whatever they are called) for an R32/R33 fit into the R31 diff?

Dont wanna go buying something and not have it fit!

Well I'd speak to some diff specialists, they might be able to build you whatever you want in your old casing and just give you new crown and pinion gears. Otherwise I guess you're going to have to swap the whole diff over for something else.

Just gotta weigh up the costs which is the cheapest.

The whole diff replaced? Or just the input shaft...

Either way... talking to 'experts' i've found to be a pain in the arse.

No-one knows when it comes to an R31.

That's a tried and proven thing.

As i can see it now... i'm gonna have to spend 'X' amount to have someone look at it, and then tell me they dont even know. Put it back together... and then leave me none the wiser and $400 in the red

Hmm.. the R31 is R200.

And it is IRS, albeit a tad different to an R33 IRS.. but IRS all the same.

Not Live like the Aust Delivered models.

I dunno about fitment though.

Do you know pete?

You've done a bit of playing around im sure

yea what v8skyline man said

the 31 is r200

the 33 dont know

the input pinion is know to give up onthe old 31 diffs... mine is a bit shagged

i replaced the centre of my diff with a 2 way cusco diff centre that i removed form my s13 silvia which is the same. drive shafts are the same but the r31 ones are longer i had to machine mine down to fit... which i guess would make them weaker

spose ill find out when i try and drift fourth or something stupid

im sure you could replace the imput if thats the problem becasue a whole new r31 housing ect cost 600 used

if its just the centre youc an get it tightened for 350 and or replaced for about 500 with a used centre( locker)

Thanks pete!

What about getting another pinion made up? Or even a stonger one?

Or is that just not cost effective... as Import 31 diffs are hard enough to come by as it is... and that means they are going to cost more and more.

Also, i was talking to chris the other day...

I need an Import Diff Bush, do you know what it is, what it looks like???

Chris said i could have one out of the car he is wreckin... but he has no idea what one looks like (neither do i) I cant get pics of it for a few weeks yet to send to him.

Mine is totally knackered and the diff moves around something chronic, probably had some part in the diff playing up.

But the S13 fits... so if all goes to plan i'll be getting a 2 way out of an S13 that is coming over.

Thanks for the help so far guys. I thought it was going to set me back thousands :flower:

    • LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.
    • I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy  
    • If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.
    • Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.
    • Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
