Fuel System Upgrade

[Bratschist]

I have been searching online for "how to upgrade the fuel system in the versa"but it is really hard to find anything in this ocean of information. I know that upgrading the fuel rails, fuel injectors, fuel line, pump and etc, gives a couple more hp to the car, however I don't know what these upgrades could possibly be. there are 600cc fuel injectors, 720cc... IDK it is just too much info out there. so if there is anybody that made a fuel system upgrade and got nice results from it, please let me know what I should do to get a bit more power on my car. Also, I would like to know anything related to engine upgrade like: spark plugs (do they really make the difference?), spark plugs wires, anything at all that you could help will be appreciated.

why do you think you need an upgrade to injectors, fuel pump, etc.?

[carlos15]

you realy dont need it unless your doing some narly a** mods

I think that's just money down the trash. Why try to spit more fuel when you don't have enough air to create the ideal burn? Get an ecu tune or an afc and get the stock map fine tuned for more power. This won't cost you an arm and a leg like replacing injectors, fpr, and fp.

thanks guys. this is really hepfull. I needen some more info and I got it. I will look into the ecu tuning, though. There is a compani, I think it's called OSIRIS and they do it, so I will look into that and let u guys know of anything else
