I'm a newbie, so forgive me if I say anything stupid. Like the title says, is the helical Type R LSD a direct swap into the GSR tranny? What's needed to complete this swap? What were your guys' experiences with the LSD? A big improvement? I'd appreciate any info.

 

Just for claification... are you talking about the stock LSD that comes with ITR's? If you are then I'm positive that it will fit in a GS-R. I have never done it and so I wouldn't know about the performance of the LSD.

 

IT will swap into a gsr tranny. I have mine sitting in my room. I have yet to install it yet!

 

If you are talkig about a stock type r lsd you may need the type r ring pinion. I know i a B16 you do.

 

Hey with an LS tranny, what would you need to install an ITR LSD? Do you need a 4.4 final drive or a ring pinion or countershaft? I did a search, somebody else asked this a while ago and got no response. Somebody help! I need an LSD!

 

Thanks for the info.

 

You need the 4.400 final drive ring gear from any B-series tranny with a 4.400 final drive (GSR, ITR, B16, etc). Then you need the countershaft also from a 4.400 tranny to slide your LS gears on. The 4.266 LS final drive ring gear has the same number of teeth as the 4.400 FD gear, AND the 4.266 countershaft has the same number of teeth for the idle gear as the 4.400 one...just as an FYI. But you do need the correct ones, as they are slightly different in tolerances. Everything just bolts right up.

Good luck.

 

Thanks a lot. After researching a LOT I found this info, thank you very much for confirming it. It looks like a little more trouble and money than it's worth. And the only other LSD's that work for LS are Phantom Grip (eww) and Quaife, and neither my car nor I are badass enough to justify getting a Quaife. Thanks for the detailed info though, it is very appreciated.

 

...Or swap the ring gear on the LSD carrier to the one off the stock slippery differential if you want to keep the same final drive.

 

Unfortunately, that won't work. I tried that, the 4.266 ring gear won't fit on the LSD differential. Thus, you can only put the 4.400 on. Then with the 4.400 gear, the 4.266 countershaft won't fit up.

I thought it was that easy too.
