OK,I need help

My setup:
95 JDM B18C in 93 Civic Coupe
Greddy turbo kit for 96 GSR 7psi boost with Trust IC
heatrange 7 NGK plugs
Boost dependant fuel pressure regulator
Crane HI 6 Ignition
check valves for MAP sensor.
stock fuel pump and regulator

Seeing as the kit was designed for the 96 up GSR, Greddy informed me the blue box (FMU) and I assume the furel injectors too. am i right?

so now i use the boost fuel pressure regulator and my boost gets to about 5psi and 4500 rpm then the power falls off sharply and sputting follows. If i use full throttle it happens, but if i slowly apply full throttle, i can rev to 6500 and past 7 psi.

when i tried to use the greddy FMU and injectors, sometimes it worked and i could rev to redline and get to full boost, but only intermittently.

could my problems be linked to not enough fuel and or pressure? The car fwel smoother and more powerful with the greddy stuff, when it worked.
can i use the greddy injectors with the stock computer?

HELP!

what size injectors are you using....def seems fuel related. and is it a greddy boost dependant regulator? vortech fmu?

 

Why aren't you using the greddy fcu/injectors? If ure not holding boost steadily, I think you most likely have leaks or need a boost controller. The best think i've done to my car was get baseline dyno tests...helps a lot with trouble shooting.

 

greddy says i cant use the FMU (blue box) citiong differrent fuel maps and emissions. reading some other posts, it seems likely i need more fuel as I am still using the stock Civic pump.

If I get a n inline pump, where do i install it? engine bay? Or would a hi flow In tank unit be best?

last thing, can I use the Greddy injectors witout the Greddy FMU?

 

id suggest going to a slightly larger injector, for sure getting an inline fuel pump (mount after fuel filter, before the fuel rail)

 

so an inline pump is the same as a in-tank? at any reat, I'm gonna pick one up maybe today if i got time.

can you guys suggest a brand and model? I expect to make around 300+ hp

thanks

 

no, intake and inline are completely different things. Inlines are more powerful then intank pumps.

 

ill assume the inline pump goes in after the in tank. I f thats so, then wouldn't the intank act as a bottle-neck to the inline? than whats the piont?

that said, any suggestions on pumps? I prefer an intank because of quietness.

 

if you are going to be using a Vortec FMU 12:1, then get a inline pump.

 

stuffed in a walbro pump tonight.

Whooooosh!

YAh...boost is good. all the way to 7800 rpm...

tomorrow..10 psi

Mwahahaha....

Thanks for all your help guys.

Honda-Tech rocks.
