I have a stock OBD1 Civic Si fuel rail, if you compair it to a OBD0 Civic Si's rail it's like the OBD1 rail is huge, is their anyway to bore out the OBD1 rail insted of buying a aftermarket item? sorry my english sux right now, sleep time

 

HERES MY question, i know bigger injectors spit out more fuel. so whats does abigger fuel rail do oppse to a stock fuel rail?

 

stock fuel rails can support upwards of 400-500hp, if your not touching that I wouldn't worry about it. Not exactly a power killer.

 

I HEARD aftermarket have ports for gauges also
