i need some help on upgradding fuel system. i got my car dyno tuned the other day and the numbers were sad for 13.5 pounds of boost only layed down 217 whp. the main problem is cant get enough fuel inside im running the greddy turbo kit and the 310cc injectors are not enough. any idea or opinions what i should get i was thinking rc 550's and aem fuel rail. should i upgrade the fuel pump or no. should i get fuel pressure regulator. thanks honda tech

one more thing do i want saturated-high resistance or peak and hold -low resistance

 

definately need bigger injectors, not sure what motor you have/what set up youve got/or what your goals are, but 310's on that much boost wont work 550's may work but again it comes down to your hp goals, i image the duty cycle on those 310's is extremely high, also mabe a walbro 255lb unit and defintely a fpr, ive heard that honda fuel rails are sufficient but i could be wrong

 

Yes some 550's walbro fuel pump and a regulator, the b&m ones are affordable and reliable, you may as well get a fuel pressure gauge too.

 

yea my turner had the babys pushing as much as possible we actually changed the rev limiter cause motor was leaning out that bad in high rpms. i would like to see at least 250-300 out of the motor. motor is a built b16a2

 

well with a good tune and proper A/F ratio 300whp is no problem on a built b16

You heard correct, stock honda fuel rails will handle 450hp+ easy. There is no need to upgrade honda fuel rails imo.
