Well I found this forum last night and I am impressed I was on another Jeep forum and they are not nearly as knowledgeable as you guys.I have already found a couple projects that will keep the love of my jeep going for a long time.Which brings me to my new project the 99+ intake manifold.I have a 96 zj and I was wondering if there was better performance if I used the WJ injectors and fuel rail?Also If I get the WJ parts (fuel rail and injectors)will it run at the right fuel pressure for the injectors or will I need to get an adjustable fuel pressure regulator.Please correct me if im wrong but isnt the fuel pressure regulator in the fuel pump assembly in the tank?

Im pretty sure they are made to run at a higher fuel pressure then the ZJ Injectors. But im pretty sure to get all the bennifits that you should use the WJ injectors. Dont forget to change the O rings while you have the manifold off. . . Much easier to do now then later. I dont know weather you could get away with just replacing the fuel pressure regulator, or weather you had to replace the fuel pump. If indeed you have to change the pump, i would go ahead and do a "Swampy Bypass" (search) so you could get a higher rated pump for less then a stock type pump.
