ok, like the title says im looking to swap a navi engine into my 02 gt and i have a pretty good idea of what to do except for the fuel system.

here are my planned specs:
stock cams since i've read they are the same as 03/04 cobra ones
extensive port and polish of the heads
cobra or mach 1 intake
frpp shorties

so my questions are will the stock fuel rail be enough? what size injectors should i run? and will a svt focus fuel pump be able to handle it?

thanks in advance for the help

 

With that, I am pretty sure your stock pump will handle it, so an SVT pump will definitely handle it. Stock fuel rail should be fine and I would like to think the stock injectors would be fine, but you could probably get some 42lbs ones if you like.

 

Stock fuel system will handle that just fine.
