like a glove

 

I have one for sale if you want it, make me an offer...

 

don't you need to change the final drive? because a usdm GSR/ITR final drive is 4.4 and the jdm itr is 4.7...or it doesn't matter?

 

Nope, I have one in my car. well....actually, it's a USDM ITR LSD, but it didn't require a new final drive. And I was under the impression that the USDM ITR and GSR had different final drives anyway?

 

the usdm itr and gsr has the same final drive, but different ratio in 2nd-5th gears

 

ya it does fit....

 

Thought you needed to run the ring gear with the LSD?

 

You need a new ring gear if you are putting a ITR LSD into an LS tranny. Not GS-R.. GS-R tranny would work just peachy.

 

bump i need to clarify one thing. is the final drive the same thing as the ring gear that bolts to the differential? and if so if i purchase a ITR lsd unit that does not have a ring gear on it all i need to do is get a gsr ring gear and bolt it to the ITR lsd unit and then bolt everything back together in the gsr tranny and ready to go?

 

make sure that you get it shimed right. If you never done it, let someone help you with it. And don't try to do it in one day cuz most likely you will not have the righ shims for the diferential. 98ctr

 

what are you talkn about... what shims? i took the tranny apart as well as the main shaft, counter shaft, and diff with ring gear and i see no shims. as far as i can tell i should be able to just bolt the gsr ring gear onto the ITR lsd diff and put everything back together.... am i wrong?

 

dont you need to shave the tranny casing to fit the jdm lsd in a usdm gsr trans?Then shim

 

Any time you replace the differential, at the very least, you need to check the differential thrust clearance (or preload depending on diff bearing type) and adjust the shim size as needed.

 

Okay.....for those who said it fits, are you sure?????

The USDM ITR LSD will fit into the GSR fine, not counting what shimming you might/might not have to do. I'm just talking about the LSD going in.

The JDM ITR LSD should NOT fit right into the GSR without swapping the final drive ring gear and countershaft for a 4.785 one.

Isn't the USDM ITR and the GSR the same 4.400, while the JDM ITR a 4.785?

I was led to believe, different final drives have different countershafts. At least this was my experience with trannies so far. I worked on a few, and saw that every FD difference had a different countershaft. Maybe this is an isolated case where the 4.785 and the 4.400 have the same ones?

 

Digital punk do you still have that ITR lsd for sale? If so let me know ASAP!

I tought you can use the gsr ring gear and the jdm itr lsd will fit into the gsr tranny and that you have to shave a little of the casing for it to fit properly. I know all i got right now is a jdm lsd and that little gear thing that it came with.

I have worked on a few trannies and every time the final drive was different, so was the countershaft. Based on my experience, not only do you have to change your final drive ring gear (you said you have that already), you will need a countershaft from a 4.785 car.

Check out the ITR forum, as many of the ITR guys do the 4.785FD swap. See if their final drive kit comes with a countershaft as well, and you will know.

 

That's my understanding too. I think 98+ jdm itr is 4.785 fd, which whould need the countershaft thing. pre-98 jdm itr should be 4.4 fd. someone correct me if im wrong.

Just a pic I found on ebay, not my lsd

For one you don't preload anything. There is no pinion gear to pre-load. For two it will fit but it may need some shimming to line up and sit properly. For three if you are using the gs-r ring gear than you use the gs-r countershaft. It will fit fine but check your clearances first.

 

well i dont know if it will work or not, but if you look at the pics, one of the holes has a stud broken off in it if you didnt know already. you prob gonna need to drill a hole in it and use an extractor bit.

Okay, two things as well.

First, the original poster isn't the one with supplying the picture. It's someone else. And by the someone else's picture, I see that the ring gear isn't supplied. Will the 4.400 GSR ring gear even fit on an JDM ITR LSD? Not sure.

I do know, however, that a 4.266 ring gear DOES NOT fit on a USDM ITR LSD (4.400). I also know that a 4.266 ring gear DOES NOT fit on a 4.400 GSR differential. So therefore, I'm assuming a 4.400 GSR ring gear WILL NOT fit a 4.785 JDM ITR LSD. See what I'm getting at?

UNLESS, however, you do know for a fact that a 4.400 GSR final drive ring gear will fit on a JDM ITR LSD made for a 4.785 ring gear. I'm curious to know.

Second.....umm....er....no, I think that was it.
