Re: fuel uprated

yup you can run a walbro on a "basically" stock motor with no tuning without a problem. i installed mine about 2 months before installing the turbo too.

Re: fuel uprated

yea changing out the pump is no big deal. it won't harm anything ... injectors on the other hand ... you ecu needs to be able to correctly pulse them and pressure should be adjusted before running the motor w/ them.

Re: fuel uprated

thanks for your replies, ok another question and its kinda related-
fmu's i know they are not a good form of tuning, and a tune is far far better but for a low boost setup are they that terrible? i mean im just looking for more info on fmu's cos i cant find a great deal of info on them, i mean why are they so bad? are they ok on low boost applications? could i use one until i get the car tuned? once the car is tuned is the fmu redundant or does it get accounted for in the tune? can fmu's be used on a stock car before the turbo goes on?
thanks in advance

Re: fuel uprated

fmus are used to push up the fuel pressure. THATS ALL THEY DO. to run turbo YOU NEED ALOT MORE THEN THAT> I have seen them run on stock motors and turbo setups. IMO i wouldn't use and FMU. listen going turbo is not for the weak of heart, mind, or WALLET. do your homework before you just slap a turbo on ... an fmu isn't going to solve anything.

Ok ... Um maybe a stupid question... I am in a sort of same situation. Im having problems on mine stock ecu with upgraded fuel injectors (440cc) and fuel pump (Walbro 255) its got alot of gas coming out the exhaust side (I only tried staring it for about 5 seconds thats it I didnt keep trying. I didnt ant to mess something up...)It would idle then just die down.. any info would be appreciated..I did order a new ecu and chipped too from Phearable.net]Phearable.net - Electronic Fuel Injection Tuning Solutions - Hondata, Neptune, Crome, Uberdata, Ectune, AEM, Honda Tuning, Widebands, Fuel Pumps, Intercoolers, Turbos, LS/VTEC, ECU Chipping, Chipped Ecus, P28...would that help on the start-up to get it tuned? I plan on tuning the same day it comes in.

Oh and 1 more thing I also have a stock FPR would that make any difference? I seen some run stock FPR's

if your needing answers, start a new thread and ask about it. just make sure the heading for it is actually worth reading.. not just like "help" or "need answers" or some other bs

but since i'm in a better mood now, then i was earlier.
yes you should have that ecu you ordered dyno tuned immediately. you may be able to run it to get to shop. just me though i wouldnt trust it. wouldnt want to blow your engine up just cuz some website says its good(mind you i realize pherable is a great website and does some pretty damn good things) but you get my point.

and yes you should be just fine with your stock fuel pressure unit. unless you plan on adjusting it up for some reason. IMO unless your crazy built, its more for show then anything else.

Well I do appreciate the help, I been going crazy with this damn kit and knew nothing about turbo's before hand... Other than what I got I apologize, back on topic.. Thanks guys!

Re: fuel uprated

anytime you change injectors for bigger then stock they have to be accounted for and controlled . you will need a computer or "piggyback" to control the air/fuel mixtures properly.

Re: fuel uprated

you know injectors have been on my mind for a while, but from what i have heard i can run stock injectors, stock computer, stock fuel pump,with a low boost (7 psi) with a piggy back system (afc-v2), keep it obd-2 and put 1000 miles on it to mesh properly(fully built H22a4) pass inspection(nc) then do the obd-1 conversion and finally dyno tune. that was my plan before the injectors, does that sound fine?
