B-transmissions share the same 1st and 2nd gear as they're cast into the mainshaft but thats it. GSR and ITR have MUCH tighter spacing for 3-4-5 with ITR being better than the GSR.
You can put a 4.4 in but it has to be from the B16 trans, not he ITR - the ring gear bolt pattern on the diff is different from the rest, but B16 and LS are the same. An ITR diff will drop in, but you have to change the ring gear (and countershaft to match). For the time/$$ involved you're probably just better off putting the US (not JDM) ITR trans in, rather than changing gears and diffs unless you're worried about autox classing.
