I saw an aftermarket (performance) fuel rail for a decent price, plus an adjustable fuel pressure regulator. Does anyone know if upgrading the fuel rail and a fuel pressure regulator will net any obvious gains, or maybe even along with fuel injectors? I recall reading that the GTR fuel injectors will fit this car but I don't remember what the outcome was, so maybe that along with a new fuel rail and a fuel pressure regulator.

With or without tuning.

 

not even alittle
