Jason81NA,82RBtt Posted October 28, 2001 Share Posted October 28, 2001 I have a 81zx NA that has a ZEX nitrous kit installed. I have a Bosch fuel pump from a 88 F-150 on my car.The ZEX kit made to increase the fuel pressure. Well as soon as I hit the nitrous the fuel pressure jumps up to 80psi, the car is just roasting the rear tires, then the fuel pressure starts to drop and the tires hook up the fuel pressure keeps droping down to about 60psi and the car srats to run very shitty.Does it sound like I need a larger fuel pump? And doen't 80psi sound like a awful lot of fuel just for a 55hp shot . Thanks Jason Quote Link to comment Share on other sites More sharing options...
