Rb25 cam sensor different??

[redrbz]

I will be buying a rb25 longblock, and would like to no what's the different between these both. I see the cam sensor is different from one another, and I have the one like the 2nd picture. I kno that rb25 neo comes with the cas sensor like the first picture. I just want to no the different since I will be interchanging my parts from below to the top one. Any help will be appreciate,

The Neo CAS is different, The difference is where they "key" themselves to the camshaft..

very late model r33 motors also use the neo/r34 cas.
