d15b jdm fuel rail upgrade needed? turbo setup
 

Will my 450cc denso injectors need an upgraded fuel rail, or will the stock fuel rail provide enough flow capacity? The goal is 200-220 hp ATM. I know I would need to upgrade for sure if I pushed it too 250ish (or would I?).

I have the s100 /w boost, and the walbro high flow fuel pump fyi.

This is on my 91 si hatch https://honda-tech.com/forums/images/smilies/emthup.gif I am wondering becuase would the bottleneck in the fuel system really be at the fuel rail? Or would the bottleneck occur throughout the fuel lines (random: do the ef's have smaller capacity fuel lines?). Replacing the fuel lines is definatly not somthing I plan on doing, but I might as well ask and see what H-T thinks. thanks https://honda-tech.com/forums/images...es/emdgust.gif
