dc4-b20V

*** 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 ----


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.

sounds like limp mode pimp code

eh before the motor blew we were almost sure that it was the fuel pump cuz if u let out of the gas a bit the car would start picking up. but i guess that never really solved it.

limp mode stock ecu doesnt like to see boost

dc4-b20V

well i have a "missing link" AKA the hack so my MAP sensor doesnt see boost.. so if my map sensor doesnt see boost i dont think my ecu see's boost?

BoostForLife

take it to a tuner and chip your ecu with a basemap for you motor and fuel setup.
Cheating the ecu is only cheating yourself.

You can only be so cheap before ---- just dont work out. If you dick around with your motor it will let go causing you to spend more money in the long run.

BoostForLife

It already did cost him more than needed to be spent, he blew the stock piston setup stupid fast. I don't think this one will last long at all also, if he keeps on running FMU's and MAP bypass ----.
Chipped honda ecu (Crome/EcTune) > and safer than anything else for a turbo honda.

Oh he is one of those, rather buy a new motor then do it right. I know a local that blew up about 5motors and then he went and got a tune from Chris. Just think about all the work and money he would have save if he had liston to me first and done as I said.

dc4-b20V

yeah its definetly getting tuned on hondata s100 just wanted to see if it was a (not enough fuel problem) but that cant be it since im running so rich i can hardly keep the motor alive
