Hi guys,
I have installed on my friend's eg civic with a jdm b 18c r engine a nos kit wet system.
We are planning to give a 75 shot.In tank there is a walbro 255lph fuel pump.
Can somebody tell me how much pressure do i have to set the fpr?

 

id go to about 42 to 44 psi to be on the safe side , but he should also get bigger injectors
