I have a b18c1.. i believe the ITR fpr will work the same but what about others like 99-00 civic SI? Only reply if you're sure.. many people say " i think " or "I heard" they are the same.. please only reply if you know

 

I need some help guys.. can anyone confirm this?

 

all b-series are the same, just bent a little different from eachother

Thanks for your input but I know for a fact that not all b-series are the same. For instance the b18a or b18b fpr is NOT the same as b18c1. This I know for a fact. Anyone else who knows for sure? B16a fpr vs b18c1?

 

 

how can no one know this?

 

my LS is the same as the b16's i just put in my car..... just the little port coming out the bottom was bent in a different position. b18a to b16a.... the reason its bent is to clear the manifold runners, cause the runners on the b16 are closer to the rail

 

the b16 and gsr fuel pressure regulator give out different fuel pressure? i believe the gsr gives out higher pressure from wut i remember because they both use the same size injectors so they have to use more pressure but thats only from wut i remember ...

 

I'm sure the b18b fits my gsr BUT i need it to give the correct fuel pressure as well.. and I know b18b stock fuel pressure is lower than gsr so NO it is not the same.. anyone else?

 

i mean honestly.... are you really woried about losing a few psi.... duty cycle will increase and correct for less pressure. want the stock specs.... i'll go get them for you....LS: fuel pressure w/ vacumm hose disconnected and pluged at idle = 40-47 psi. fuel pressure w/ vacumm hose connected at idle = 31-36psi

gsr: vacumm dis-connected @ idle: 48-55psi, connected @ idle = 39-46psi

8psi difference max... not enough to worry about

Yes I am worried about 8psi difference. I want it to be back to stock settings.
Thank you for your input however.

Anyone else know if the b16a has the same fuel pressure settings as the b18c1?

 

bump for this guy

BrokenEF9...you know why

 

just cause i'm a nice guy i'll give it to you. you better appriciate it 40-47psi fuel pressure at idle for the b16's FPR..... thats just a little more fuel than the gsr....
