Hello everybody, I'm new in this forum and I have a question. 2 years ago I started to fix up the engine on my 2000 civic si. I installed on it headers, intake, adjustble camgears, manifold, msd coil, spark plug wires, distributor cap. now I want to continue fixinf it. I want to install a fuel regulator but I don't know onwhat fuel presure I need to set it, would you help me find out what fuel presure I need or what do you think I need to change next on my engine.

 

Pretty sure stock is 43 psi, but you should be safe in the 40-50 range.

 

Thanks

 

but do you think I need to instal the gas regulator?? or what other upgrade would be better for my engime??

 

Well, it sounds like your off to a good start, if your looking to stay NA i would recommend a nice set of bump sticks (Skunk2, JUN, TODA). If you want to bump up the pressure a little bit, I would suggest picking up a AEM rail and FPR, they will look good together and are reliable.

 

ok, thanks
