So here is the fuel pressure problem, to what psi should i set it , with my old cx fuel pump i had 34psi idle and 40psi at WOT with the vac line on The motor is b16a I/h/e timing at 17btdc ..
with my holley fuel pump i had 39psi idle and 44psi at wot and my cat fell apart so i gutted the cat and had lean condition (white spark plugs) .. Well now i got a new cat and just put my B&M fpr on and i'm on 46psi idle and 50psi at wot No smoke or anything what a correct setting would be with my setup.... help asap.... all those readings are with the vac line ON>>>

isn't that little too much for a stock motor.... test drove it and now it responds kinda better hard to tell and my idle now seems steady not jumping around like it used too....

 

I dont know how much you should run with the CX fuel pump, but I know stock psi at idle is 38psi with stock Fuel Pump. Now I'm thinking d series fuel pumps are the same as the B16 fuel pump. Not sure though. I know the B16 pump flows less than the gsr/itr pump, but not exactly how much.

I have a turbo eclipse fuel pump, which flows a little more then the stock B series pumps. I currently have my fuel psi set at 32psi at idle. No smoke(fuel) at WOT.
