Today a guy at my shop was telling me about adjusting the Fuel Pressure Regulator on my car. What a difference! It feels like I have gained like 5 extra horsepower? It doing really well now. I wanted to know how much is to much. Its at 45psi right now. It was at 20psi. And how do I check to see if my fuel pump is not a stock pump. Is it inside the hatch part of the car? Where the wires run down inside this plate that my back seats goes over. Its a 88 civic hatch.

 

what kinda shop do you have?

 

wholy shit it was at 20?

 

its a stock pump as far as i know jaymon

 

ok thanks man, whats a good fuel pump to use? And do I go with one for a 88 civic or a 93 ls? And Jason it was like 20-24psi. I don't remember but its made a lot of a differnce. It use to fall on its face in high rpms but not anymore.

 

it musta shook loose or somethng. cuz me and john had it set at like 35psi after i dynoed.

it makes hella differance. i gained 3hp by adjusting it down 2psi

GET HONDATA. and skunk2 intake mani and cam gears and thats 185+whp easily

 

working on it. Too busy to even go buy one. Jason what stage where you going to buy?

 

how do increase the fuel pressure?

 

if you have a gsr I think those have one stock. Its just a small size open ended wrench and then I just used some pillars and being careful not to round off the screw. right is down i think. Bo adjusted it not me. Your fpr, well on mine is on my fuel rail/ top of the ITM.
