Whenever I go for a smog test, I always pull the turbo system out along w/ all the fuel components...now that I'm going to add a 255lph intank, I was hoping I could leave it in when I test...As you all know dropping the tank is always a PITA...everything else will return to stock...injectors, FPR and ECU...

 

you wont pass. you'll be running wayy too rich.

 

you dont have to drop the tank to install the fuel pump. just raise the seats and pull the pump out. there are a few more things to do, but you get the point.

 

Sorry, not in a 91 civic...

 

wouldn't he be able to just lower the fuel pressure?

I have a walbro in my crx, i know your pain...who knows what i'll do when it comes emission time.

 

if you had a vafc, couldn't you really lean the car out before inspection to where you are almost lean?

 

lower the fuel psi if it is a prob., or couldnt you use smaller then stock injectors?

or ive heard of people unhooking 1 sparkplug and 1 fuel injector. if you dont pass emissions on 3 cylinders, there is no hope.
