Hey guys/girls,

Just a quick question - sometimes when coming out of a corner hard in first gear, the LSD won't lock up and will only spin one wheel. However, as soon as I put it into second gear, both wheels start spinning and sideways it goes.

It's weird though, sometimes it does lock up fine, but most of the time it won't, mainly noticable in the wet...

Is there any reason for this? Is that the way stock GTS-T diffs are built, or? Will change the diff oil help this? Or is the LSD simply getting worn out? I find it weird that it always works perfect in second gear, leading me to think they are designed like this? Everytime i've done a burnout at the drags, both wheels lock up fine...

Any advice would be great.

Thanks,

Tommo.

has it always done this? or only just started happening

I'd say your stocko viscous lsd is probably just worn out. Try doing donuts in 1st gear, and see if you can keep the end out. Stock viscous in good nick should be able to keep it going, a worn one will crap out and single spin.

I've never really been giving it much before, especially around corners!! However now i've learnt to drive RWD beyond the limit, I've been testing things out, thats when I noticed it won't be locking up in first.

Merlin, that's gotta be the best excuse for doing heli's i've ever seen in my life :D I'll try doing a few quiet ones this weekend and see what happens. I'll defintely look at changing my diff oil anyway, as far as I know it's never been done before (since i've owned it, anyway)

I'd say your best bet would be to change your diff oil. Motul pa 90 is quite good for diffs, and at 20$ for a tin, you can't go wrong. it'll save you so much stress thinking about whether your diff is warn out etc.

It is very easy to change as well.

When I got my car and changed the oil, the previous owner must have never changed it, because it was black and so thick it was almost solid. Required a good two changes before the oil was clear. Lets just say that afterwards, I was smiling. :D

Merlin, that's gotta be the best excuse for doing heli's i've ever seen in my life :)

oh hell yeah! we have our own designated "diff testing area" we use to test diffs to see if they are worn or need reshimming when testing a car for drift-worthiness... if you can't do proper donuts, your diff isn't locking well enough!!

Sweet, i'll head up to Unique and buy some on Friday... I want to get my gearbox oil done at the same time, sounds like a good excuse to me :):):)

Gotta love how the diff is on the way out with only a claimed 56,000kms.. damn jap cars and their false odometer readings :D

Hey mate,

I ended using the relavant redline oils for my diff and gearbox.

Gearbox is BEAUTIFUL, makes it very very nice to drive with :D I'd recommend it to anyone, even if your gearbox feels fine :)

Diff is also much better, but not as noticable as the gearbox.

Either way, for a couple of hundred bucks, it's a pretty cool upgrade :):):)

Cheers,

Tommo.

Defintely made it better, if i'm not turning too much in first it'll defintely hook up.

But if I come out of a corner in first at 45 degrees to the road, it'll generally spin one wheel until I go into second gear.

I haven't tried helis yet.

Hey Guys

I have changed the oil in my diff as well to the redline stuff a while ago and the single thing in first still happens. I think its time fir a reco.

My diff is very similar however it will only light up the rear right, extremely noticeble in the wet, if I flog it around a right hand corner the ass kicks out and the right goes nuts. If I do it around a left hand corner then the rear right still lights up but its sketchy but doesnt really let go. In the wet even small overtaking/turning makes it light up.

Damn pos stock LSDs.

This is in a HR31 as well. Time for a mechanical LSD I think.

    • I'm hoping I just don't have to do an engine rebuild NOW. Doesn't mean I won't do it at some point. I think a plus point is that the car presumably ran on or close to stock power nearly all it's life so far. Only the Owner I bought it from actually increased power with a standalone ECU and blew the OEM turbos. And after it got thee 2860s it wasn't driven an awful lot either.   That is what I meant. With the twins coming on so late (4500-5000rpm) I hope the rods won't want to exit the block prematurely. And it still being a 26 means the torque curve isn't gonna hike up all that much.   It didn't blow up on the dyno when they tuned it to 500ish crank. So I suppose it'll be okay for now. They did put a Tomei head gasket on first though which did not seal at all, and they redid it with a Cometic one. Which I hope won't be my water leak.   Mainly anything oil. So far all it has is the N1 pump, oil restrictor and a filter relocation kit with a cooler.
    • 15000? ish? Something like that anyway. It wasn;t so much a wear as a tear that then spread. Might have lasted a lot longer if not bothered by just one incident, whatever it was. I took a punt. They are really comfortable and do a good job of holding. My daughter HATED it when I first put them in, and probably still does now. She has sensory issues and hates the way they are all up your business. I'm 197cm and 95kg. Not fat or particularly wide, and the XL size seat is the rigth fit. If I was any fatter it would start to get too snug. Any skinnier and you'd possibly want the smaller width.
    • Mrs rs focus came factory with recaro cs  sportsters in it and they a pain in the ass to get in and out of with the really high bolsters, once you were in them they were one of the most comfortable seats I have ever sat in
    • The NA 2.5 has very little torque. You won't feel much. Those trannies are also a million years old now and it could well be f**ked. First generation electronically controlled autos will often refuse to kick down, ete, etc, depending on what's wrong with them.
    • Yes, but no but yes but no. Those "it's fine up to 500HP" rules and everything else like it were all determined back when the cars were 10 years old. As they are now 30 years old.....what do you reckon the chances of something shitting the bed are? I'd say they are much higher now than they used to be. You might be lucky. You might be unlucky. Spin the wheel and find out. Yeah, nah. It's actually exactly the opposite. Making boost early and having heaps of torque able to be generated right in the middle of the rev range will do more to damage an engine than having to rev it high to make the power. Think about the load on the conrods, bearings, etc, to make 400HP at 4000 rpm, vs 400 HP at 6500 rpm. So someone has already "let the Nissan out" which is how we describe the increased chance of a fiddled with engine to have had something done wrongly. Many more engines that have been opened die than stock ones do - even if you into consideration how they are treated wrt power levels and the like. Again, not saying that yours will definitely have been put back together by a moron. But the possibility does exist. It's still a lottery. Spin the wheel. What weakspots?
