Probably talking about the fuel pump. You'll need to upgrade the fuel pump to a high pressure one.

 

you also need the SR engine harness and if your S13 was a SOHC you will need the powersteering lines from the SR also, make sure you have the KA speedo sensor or you will be reading in KPH, Heavythrottle.com has all the info you need.
