*** FOR THE LAZY PEOPLE THAT DONT WANT DETAILS HERE IS A SHORT VERSION AFTER ABOUT 3K CAR COMPLETLY LOSES POWER I THOUGHT IT WAS BECAUSE I WAS RUNNING IT ON A STOCK FUEL SYSTEM THEN I GOT 450CC INJECTORS AND A 255 WALBRO FUEL PUMP BUT ITS STILL DOING IT, PROBLEM CAN BE CUZ THE CAR IS NOT YET TUNED THATS WHAT IM THINKING JUST WANTED TO HEAR THOUGHTS***
____________________________________________________________________
for those that wanna read :
just a side note to the people that are gonna flame with "why are you driving a un-tuned car!?" -answer is becuase if anything is to go wrong i want it to go wrong on my first pull cuz if u take it to a tuner and it blow up u still gotta pay him and hes not responsible.
It probably isnt but i have never ran into this problem before in my entire life
heres basically the build
junk yard turbo kit home fabbed and shit
i built a b20vtec and decided to turbo it cuz it was low comp so i finish the motor and slap on the turbo kit and decide just to take it for a few spools to make sure it was all correct tho at this time i ran using stock fuel pump and stock injectors, when i would hit about 3-4k RPM the motor would just go face down lose all power almost as if the fuel pump just completly shut off. so i ended up cracking ring glands on the piston. so i go back to the fort and this time pick up some manley pistons, ported the head and i did a few other things ARP rod studs etc.. and this time i put on some 450cc DSM injectors with a walbro 255 fuel pump
and i just noticed that my 94 integra LS does not have a resistor box for the injectors so i picked one up. I do have FMU it might be a 1:1
anyways too much bullshit im talking too much, has anyone herd of anything like this happening?
to sum it all up im thinking its only doing this cuz its untuned & or i might need to get a fuel pressure regulator even tho i have a FMU.
