That's correct.

Excellent. Thanks for clearing that up.

Where can I buy this LSD? After oil cooler, pads, and fluid this is to be my next mod so she can be track ready.

You can purchase from Forged Performance themselves. Call for best pricing.

We can take care of all of your track needs.

I just sent you a PM!

We were planning on it. But being my car had only 2000 miles on it they were in great shape. But with some milage on them it's best to go ahead and replace along with the seals. I'd also look into the Nismo differential cover with the cooling fins. I should of picked one up before I had this installed.

Here's a link for the part number. Which can be had at any dealer. Just confirm with Nissan this is the right part though.

Yes it's good to swap to a true LSD over the stock VLSD which isn't great for the true enthusiast who will push the car more beyond DD like lots of spirited driving and defiantly track and auto cross. The stock unit will heat up and basically will act as a open diff like the base model.

The OSG will fit in any model just the base requires different axle stubs.

So I wouldn't need any additional parts like you did? I assume I would need seals etc?

To bad Forged is in GA...too far :/

SPHON,

I just had the OS Giken super lock installed in my 09 base model.

Did you have any issues with the ABLS (Active Brake Limited Slip) still on? i.e. does it interfere with the clutch LSD operation?

I don't think there is a setting to disable it via UpRev...

No, no issue at all. So your saying it stays on all the time? Was the speed sensor reinstalled or possible damaged on the diff? Either way it shouldn't effect drivability. It's all mechanical.

No, it doesn't stay on all the time.

I don't think the speed sensors are an issue, but I haven't pushed it hard enough yet for the VDC or ABS to kick in.

That's what I wanted to hear, that having an ABLS enabled ECU doesn't effect drive-ability of the CLSD

The roads are finally drying up a bit around here, so I will get a chance to really test it out soon.

Thanks SPOHN! This thread really helped me out

I have been told by a couple of people now that the OSG for the base 370 in 7AT configuration which uses part number NS113-HA requires no stub axles and that it is a direct replacement and drops right in. Is this true?

It seems like there is conflicting information now. I understand the fact that Nissan designed several stub axle variants throughout the model years and that makes it a bit more complicated. All I'm trying to do is make sure I order only the parts I need to make this a smooth and quick install and be done with it as this is my DD. Down time is not an option for me. So can someone please provide some consistent information? I tend to believe the ones that did the install, such as Forged. That is all fine. But is there someone from Giken that could chime in on this as well?

And not to go off on a complete rant but it seems that every topic on this forum has contradicting information on every subject covered and the oil cooler issue is the most frustrating by far. So in light of that, I would like to here from an expert or the manufacturers if they are reading and feel like replying. I just want the facts. That's all. I just don't want to hear from one that I don't need anything extra (except bearings of course) and then another says two right side stub axles. It makes my brain twitch and I turn into something that looks like the demon chick from the Evil Dead remake. Makes John very upset.

I apologize in advance for my ignorance and since the conversation is already going I thought it appropriate to ask here:

On OSG's website they list the z33/z34 together when you sort them by manufacturer and it mentions it's for the AT only. I have a sport package z34 with MT, is this going to be a problem to install? Am I missing something here? See link below:

Product

Another thing is that I had planned to get some KW v3's with my tax return money, however, I know I'm eventually going to need a proper LSD for the track as well. Which one do you guys think would be the better early buy? I think our stock shocks seem pretty good with sways but I'd like to have more experienced opinions.

Thanks and sorry for the slight thread jack!

Penguin, go for diff first

dP3NGU1N · 02-27-2013, 05:54 PM

Anyone know if this is the right OSGiken LSD for a 370Z with sportpackage 6mt? Is there even a diff between at vs mt LSDs?

R34 LSD AT only?
