Ive got a 2001 GSR with a turbo kit on it. Right now, I have a 12:1 FMU on stock fuel system. I have recently bought a walbro 255 fuel pump, fuel ressure regulator, and an OBD1 P28. I was wondering which type of injectors I need: I want Precision 880cc's, but I am confused about the high/low impedance, delphi, and saturated types. Which ones should I get, and yes, it will be tuned. Also, which type require a resistor box and will I need injector clips? BTW I want the 880cc's because I am going for 600hp build, and my tuner said injectors can be tuned down, but they can only spray so much, so I'm getting big ones just to be safe. Thanks in advance.
