Injectors for 14psi KA - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I plan up upping the boost to 14psi on a KA after I ugrade the pistons and rods. What injector size should I use?
I will be running 7psi until I up the internals, so I only have to buy injectors once, is there any downside to using injectors that are overkill besides using extra gas?

What are some good injectors to get and where? Price?

Do I need to upgrade the fuel rail to fit the new injectors? I'm guessing they're going to be about 530cc/min injectors? I'm going to upgrade the fuel pump and filter when I put the turbo in. The 300ZX injectors only go up to 370cc right?
