Incorrect. ITR LSD will fit in any Hydro b-series trans case (except RT-awd crv - without modification) with either tapered or ball bearing differential bearings. B16 (4.40) & LS (4.26) ring gear will not bolt up to the ITR LSD. GSR (4.40) ring gear will bolt up fine.Dave_B wrote:The ITR LSD will NOT fit in a GS-R trans.
It will in a B16... but not the GS-R trans.
So let me get this right (different from what I have read/heard over the years) it will bolt into the GS-R trans with NO MODIFICATIONS? I've always heard it different that the number of bolts in the ring gear is different on the GS-R but that the B16 trans it was a bolt in affair.D wrote:Incorrect.

I'm not sure if you're smiley was sarcasm or not... but the info you posted is incorrect.
LS = 4.26 FD - Small ID ring gearDave_B wrote:More info please.
huh? ID/OD...... the differential has a smaller OD (and is physically smaller), the ring gear has a smaller ID. pick one.Dave_B wrote:Yes, is that OD, not ID?
And given close diameters, again I thought it was bolt holes, not the diameter. One would think, you can have a smaller diameter, yet still line up the bolt holes (given that it's not to much smaller and there is still ample room for those holes in question)
But again... I was always under the impression it was more the bolt holes on the ring gear that was the problem and not the diameter of that gear.

They're not close at all, the B16/LS ring gear will NOT fit over the GSR/ITR diff. Period. The bolt circle is also smaller, so if you wish to use that as your justification... sure. The ring gear has a chamfered edge on the ID, and a close tolerance fit to the corresponding lip on the differential housing. They are not interchangeable.
I have seen some other OEM differentials that aren't 10 bolt... i have yet to have my hands on one of these 14 bolt diff's... and i have yet to see a DC2 ring gear with 14 bolts on it either. shrug.
Edit: The final drive ratio is not related to the size of the differential....... the 4.40 B16 ring gear has the same OD as the 4.40 ITR/GSR OD. Understand? (edited previous post for clarity also)

If you wish to change out the 4.40 small diameter ring gear/diff in a b16 transmission to a 4.40 from an ITR/GSR, you will also need a GSR/ITR differential. If you wish to put in a LS 4.26 FD, all you need to do is swap the ring gear and countershaft. The LS ring gear bolts up to the B16 diff.Dave_B wrote: Let me ask you this then... can you change the ring gear in the B16 trans to that of the ITR trans? To eliminate the ID clearence issue?
But again, can you swap the ITR/GSR ring gear into a B16 trans and make it work?

go check out quaiffe/obx/any aftermarket diff... it will come in 2 sizes, large (GSR/ITR) and small (B16/LS/GS/RS). The corresponding sized ring gear goes to that diff.

Correct. All B series hydro cases are the same (except of course the CRV AWD unit - dual ring gears, cable actuated shift, starter rotated to front side of bellhousing) so the ITR LSD will fit fine in any B16/LS/GSR case with the corresponding differential bearings (and all of which can be converted to the newer style carrier ball bearings).Dave_B wrote:So then, if I gather correctly from what your saying... I can take a B16 trans, and swap the dif and ring gear and be ok, no issues at all with clearence or fitment?
Just dropped the motor in last weekend, axels are going in tonight along with welding up the shift linkage. Waiting on some parts to arrive at local dealer. Might get to do startup within the week.Dave_B wrote:Now get that other R built...
Well shit... I've got a "broken" GS-R trans... and was thinking it wasn't worth tracking down parts for it. LS swap with GS-R/LSD equiped trans for the hatch might be on the list to do shortly.

I have most of the parts for the rebuild, missing ABS fuse box, door pannels, carpet, and some other misc crap. Mini has more parts laying around.. trying to get ITR2 and wagovan running by winter. Play with the mini hopefully soonish.Dave_B wrote:I've heard she looks great. Anything else she needs to be road worthy? Speaking of D's infamous projects... how's the mini coming?
