I have a 81 280zx NA, I am close to getting the turbo engine together and into the car...I am using 440cc injectors, 255lph walbro fuel pump, areomotive FPR, JSK fuel rail, I was wondering if my stock fuel lines have to be upgraded to something bigger? I am going to be running a t3/t4, I want to run 15-18psi of boost. How much can these lines flow? and what do you suggest I upgrade them to if insufficient.
thanks.
