you don't have to, but most people do. you will need a new fuel rail and injectors to do top feed.

Greddy and a few others make a side to top feed fuel rail for the 25
or there are prenty of nismo injectors in side feed to fit your stock rail

it depends on what manifold you use, the greddy for rb25 comes set up for top feed

You don't. Stock rail bolts up just fine. Just don't loose the hard rubber (plastic?? dont remember) spacers when it comes off.
