The part #'s dont match here in the USA but if you go to "owning" then "parts", Then "Passenger vehicles" From there chose any car Sr 200Sx/180sx Europe, etc. It will break the car down for you in a diagram. Its pretty cool site. A guy from the Nissan dealer gave it to me who is hardcore. NE way enjoy.

Thats the Nissan of South Africa website. The parts numbers appear to be correct. The reason you will not find corresponding numbers in the US is because the US never carried S14 SR20DET's. But just to reiterate, some of those parts numbers match the numbers on parts of my S13 SR20DET.
