everyone got just most of the stuff, so i will repeat somewhat.

RHD (of course)
B16 Engine
Bigger Front brakes
Slightly different front end - dip in the hood goes UP not DOWN like US Si, Wider headlights, wrap around bumper lights, different rad support with different OEM intake piping, clear corners, sidemarkers. The entire front cross member is different from USDM.
Tail end: Different Taillights (CR-X VTEC logo on center garnish), 3 legged wing (NO LED; 2 leg LED wing was on an EF7, model down from SiR), bronze tinted glass.
All glass roof
Power Folding Side mirrors

Interior
Power windows - with different door panels (I dont think the JDM CRXs had Power locks though, have never seen it in my pics)
Auto AirCon
Leather Seats- JDM look very close to USDM, but the outer part is leather, with cloth middle. EDM vti (SiR) has ALL leather seats with CR-X VTEC logo stitched on in red
Leather wrapped steering wheel
Different Gauge cluster
Rear Seat
Maplight
Sunvisors-Black, not the light gray like US
Gathers Premium Sound system (optional)- Double DIN radio with CD player and special rear speaker covers with HONDA PREMIUM SOUND badge

Last thing is they had a DOHC VTEC logo on the doors to promote what was under the hood.

i think i got about everything I know all this cause i have half of these parts on my CRX now
