I have another question that you might be able to help me with. Here is a little background. I have a 97 civic hx coupe. I installed a b20b with b16 head. I am running a p72 obd2 setup. I have 12:1 compression pistons. I plan on getting ahondata and going obd2-1 when i get the money. Anyhow my car was pinging so i had to retard the timing to about 14. It still pinged when it was cold. To stop the pinging I installe d an adjustable fpr. I had it set at about 40psi. IS that ok for my compression. Then a week later i installed the walbro 255 fuel pump and a new fuel filter. I adjusted my fpr as far as it would go and now it idles at 50 psi. I can not get it any lower. However now when i give it gas it accelerates and then seems like it boggs and gets sluggish and then picks up again. Is this because it is running rich? If so what can i do to avoid ping, have better throttle response and the psis? Do you think I should move the timing back to 16 degrees? Also is it possible through wrong timing adjustment to have a rod hit the piston or whatever its called?
Cliff notes:
High compression --> Ping + retard timing -> FPR + Fuel Pump
-> FPR won't go under 50 psi -> Car may be running rich and bogs -> What to do ??? What psi should i be running?
Thanks
