ok, I'm going to set up a Walboro fuel pump with a 100 shot of zex nitrous. I'm runnin a 65 shot now without the pump and have no problems. I've also changed the plugs already. So my Q is, when i hook up the new pump and the 100 shot, is it suggested that I get a FPR, or dual FPR's? And if so, which ones should I get? I had a paxton on my old civic and didn't really like it....Thanks for the help.

BTW, I have a 99 SE-L 5 speed if it helps...

 

You need to get a FPR if you want your fuel pressure to be back to OEM spec.

 

What would it be without a FPR and that pump?

 

It would be aleast 4 psi more.
