anyone using aftermarket fuel rail for b20 vtec? what brands, is it necessary 12:5.1 comp

 

stock fuel rail should suffice you, i am using a GS-R fual rail on my b20/vtec just make sure you have a FPR, i run mine a 44psi on idle - b20/vtecs are fuel monsters...

fuel rails are for bling bling unless you have high amounts of boost (12 and up)

my friends with an si was running 14 psi on stock internals and stock fuel rail

 

I'd probly go with AEM or STR
