I have seen the aem fuel pressure regulator for the b16 ( 94-97 vtex delsol and 99 si ) with either offset or inline soted in the description. what I want to know is what is this refering to and is there a preference when putting this on for a turbo.

 

A fuel pressure riser or regulator is a module that baisically adjusts your WOT fuel pressure.

For forced induction applications you need an FMU.

 

I will be running hondata and they require a 1:1 rising rate fpr ( thus the aem fpr ) what I am wondering is the diff between offset and inline.

One sits in line one sits on the fuel rail....

 

i dont suggest an fmu, they really put alot of stress on your fuel pump, if have a good pump then you dont need your present one to be pumping at max rate, when you go into boost....think about it 12:1 12psi for every one pund of boost so 10 psi of boost equals 120psi of fuel pressure, most stock pumps max out at around 70-80, and then bleed off excess............i say get a nice pump and use the AEM. also fmu's go bad and you dont know it and cause your car to idle fatt as shit and run really rich
