Hi people, sorry if there is a thread on this already, i searched for it but couldnt find anything regarding this directly. I just purchased a new nismo fuel pump and fuel pressure regulator (for my r33 gtst). no major engine mods apart from pod, fmic and ebc. bought the pump for the sake that im getting a custom boot done and affraid that it might be a struggle to get the pump in afterwards...
1) will i need to upgrade anything eg fuel lines???
2) is it ok to just replace the stock pump, leave the stock regulator (for now) and install nismo pump??? (ps: will eventually upgrade ECU to autronic one)
3) what about installing the regulator??? i know its adjustable, or can i just leave it off for now till i get injectors and ecu upgrade???
any suggestions appreciated ay...
thanks in advance, Jon
