I just got my Zex kit, and I know I can run safely with stock setup, but I want to get a bigger fuel pump because I heard it helps, i also heard bigger injectors help as well...however thats the only thing I heard reguarding those 2 topics. What size fuel pump and injectors should I run? Its a 2001 Tib.

 

i have a 02 elantra xd. i was spraying an 80 shot for about 8 bottles. the only fuel upgrade i had was a 190lph fuel pump. no bigger injectors. you should be fine with a 190lph or a 225lph pump. also, since you have a return style feul system (i have a returnless fuel system), you may want a fuel pressure regulator. and if you have an auto, make sure you install a trans cooler. have fun spraying man, you going to love it.

 

no need for a bigger fuel pump. the stock one is good enough. i run 8 lbs of boost on stock pump and my a/f is still sweet
