Basic question , an after market hks Fuel rail, to suit RB26 in gtr . Two sizes , 11mm or 10.5 injector ports, will the capacity of either one be same in the fuel rail it's self.
That is to say, will the 11mm hold or flow more fuel , i would personnaly think not.
2nd question. What is a good fuel regulator up grade to suit this rail, that will fit on with minimal fuss and has rising rate and good flow and reg ability
