Title: can a itr lsd diff be modded to fit a ls?
Post by: highroller54 on September 06, 2010, 04:26:07 PM
I've never had one side by side, I know you can swap final drives but I need the stock ls gear ratios so thats out. Any other ideas other then just getting a m-factory lsd?

I was told from m-factory that a b16 diff lsd will fit LS trans. You will need to shave some of the trans case.

really? I was told the b16a factory lsd had a different bolt pattern then the regular open b16 diff.

It will work just fine if you use a GSR final drive set.

 :P

The bolt pattern for the ring gear is the main thing that keeps the ITR LSD from working with an LS transmission.  The GSR/ITR use a larger bolt pattern ring gear than B16/B17/LS ring gear.

yes, the itr has a 116.8mm whole in the gear and the ls is 109mm. Can a guy machine down a itr diff and redrill the bolt pattern? Is the flange were the ring gear sits the same hight?

use GSR FD and CS with LS gears????

only 3% difference

7000 rpms with LS FD = 7200 rpms with GSR FD......

B16/B17 has 130mm bolt pattern and 110mm crown opening

GSR/ITR has 138mm bolt pattern and 117mm crown opening

Kiwi at GearX was telling me they had tried making the ring gears with 117mm crorn opening and dual bolt patterns without issues.

I have thought of that but I'm already under geared for what I want. Supposedly a y1 jdm lsd diff fits, but from what I hear they are one piece (cant take off the ring gear??) and that could be tough to find.

Quaife/MFactory/OBX.....ITR diffs are weak anyways.

yes but there is no way this build will break it, lol.  I was trying to be cheap as I dont need to pay for the overkill on parts

Like using LS rods in a D16 when after the costs they end uo costing more that the cheap H beams.

Stock ITR power can break the ITR LSD.....

Quit being a broke dick :)
