I’m kinda getting confused on the order of things I should do.
I basically have all parts needed for a 4g63 head swap.
So far all I’ve done is installed a FueLab fuel pressure regulator.
I then started with replacing the stock fuel pump for a Walbro 255lph.
Got the old pump out, did the pump swap. Then realized I should change the gasket. Which ofc I don’t have. So it’s on order.
But I also have the hardwire kit for the fuel pump.
I’m a bit confused if this hardwire would have any effect on the relay bypass I plan on doing. Or if I even need to do the relay bypass if I hardwire the fuel pump?
Also, does anyone know the target PSI on the fuel regulator I should aim for with these options;
SOHC stock injectors, stock ECU, no turbo
SOHC 680CC injectors, ecmtuned ECU, no turbo
DOHC 680CC injectors, ecmtuned ECU, no turbo
DOHC 680CC injectors, ecmtuned ECU, 16G turbo
