Do I really need one or can I stay stock? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

As many of you know swaping out the KA for a SR is some hard work and a lot of money.  I am trying to do my best, but I have been told that I am over looking the fuel pump.  The motor will be stock excpect for turning up the boost to 14psi (1.2 or 1.3 bar) will my stock fuel pump be ok?  If not which one should I look at?  I have been told the (non-turbo) 300zx will work.  Is this true?  Can anyone give me parts numbers?  Also is that my only choice?  If I have to get one I want a intank pump.  The other one are to loud for me.  Anyone have spec. on the 240sx fuel pump? and what the 300zx is? and what ever you guys say I should get?  I don't mind paying more for a better unit.  I would rather do everything right the first time around.

On a side note Since I swap out the fuel pump do I need to swap out the injector out also?  If so what size am I looking for 550cc?
