fyi the EK9 or ITR is a 1 way torsen diff.

Not 1.5 way. Also , it will fit with minor mods to the diff casing ( to fit the larger diff bearings etc)

The ITR unit is not a 1 way LSD. "way" is solely reserved for Plate Type LSD's that lock; an ITR unit is not a Plate Type and does not lock.

Infact, a gear type differential is not even a true LSD (Limited Slip Differential), they are Torsens' (Torque Sensing Differentials). The word LSD (in relation to Torsens') is used purely for marketing.

Abit of clarification

You don't require mods to the diff casing at all (shims take care of any thrust clearance issues). You can use the same 18mm bearings.

The only difference is the B16A's smaller diameter ring gear versus the B16B/B18C's larger diameter ring gear.

If you swap out the ring gear (and countershaft to match), you can fit the LSD.

changing diff for EK9 box here.
new diff comes with ball bearing+1.5mm shim. old diff has taper needle bearing.
wat else do i need to change? or should i look for the appropriate needle bearing instead?

That's fine, the B16B/18C uses the 19.5mm ball bearings (hence why you have the standard 18mm B16 bearings + 1.5mm shim). Honda discontinued the taper bearings.
