I was wondering if you think i will need an FPR and fuel rail if im going to be running about 10 psi on my B18B1 with a T3/To4e 57 Trim turbo. I will be running 440cc injectors and have the system tuned properly with hondata or maybe neptune. I am aiming for close to 300whp and im also thinking of turning it up to 15psi for a couple 1/4 mile passes.

Do you think the FPR and fuel rail are necessary or not?

 

you dont need it

 

when would you say they would be a necessary addition?

 

around 400hp i think

 

yeah i figured it wasnt necessary but in the kit im looking at it has an AEM FPR and fuel rail and im not sure if i should keep em, install em or sell em?

 

I'd keep the FPR. I wouldn't know how to adjust my fuel pressure without mine.

Ditch the fuel rail though. It's never the limiting factor in your fuel system. If you need more fuel, just get a stronger fuel pump and adjust the fuel pressure.

 

aeromotive fpr

 

so you guys think i should keep the FPR or maybe look into one later on since some people dont think its necesary?

watch the AEM FPR. the diaphrams have been failing here lately.

 

im gonn substitute a walboro 255 in for the FPR and rail:D

 

Why do you need a Fuel Pressure Regulator? Just get the right size injectors to begin with.

Only get a fuel rail if your shooting for over 400whp.

You're missing the point. He's not "getting" anything. The rail and regulator are already coming with the kit he's buying.

 

sell them ... or substitute -- which he is doing/ smart guy.

 

yeah the kit includes the FPR and rail but i didnt think it was necessary so im gonna substitue em.

u guys think i shoudl do 440 or 550cc injectors when aiming for 300whp?

550's for shure

 

heheh good price but there included in the kit, wondering if 650's would be too big?

 

I heard that using a bigger fuel rail will prevent the pulsing effect that you will get with larger injectors.. I figure for the $120 or so why not get one..

On my setup I kinda need it since I use an Aeromotive FPR that doesnt bolt on to the fuel rail..
