I have a 96 EK with a 95 Integra LS motor on Nitrous. The top end is fully built but the bottom end is stock. Im running a 85shot NOS. Is the bottom end ok to take that much nitrous.. Please give feedback.

 

yes.

 

why did you build the top and not the bottom if you are FI?

 

Ok thanks But my main concern is that my fuel pressure drops really bad under heavy load so I bought a Walbro 255 intake fuel pump and installed it. But when i did that the fuel pressure stays at 80psi at all times and i cant seem to get the pressure down at all and i have aa adjustable fuel pressure regulator too and when i try tuning that the pressure still stays the same. Please advise

 

Money factor there buddy. No more money to build bottom end..hehe

 

Your fuel pressure is 80psi?! You have something hooked up wrong, especially if you adjusting the FPR does nothing.

 

thats the thing i installed the pump just as it says to. do you think the fpg is too same to push all that fuel back to the tank?

 

u need to look over everything again because thats wrong if your FPR is the same no matter what you change
