i finally got my b20 turbo running, and it was popping a little at first, and that was traced down to bad injectors......the injectors have been replaced but it still seems a little lean.....the plugs don't have the splatter on them but they are a lil whiteish looking.....the electrode doesn't look like it's too hot but i'm not sure what it should look like in a boosted motor......is there anyway to richen it up??? i have a stock b20z and a ls ecu......with stock injectors......and an fmu, i beleive the fmu is 12to1.....also i've heard you can use a fpr with the fmu.....would this help my prob??? i'm also running the bcpr6es-11 plugs

 

anyone????

 

how much boost?

 

I was just wondering how you traced your problems with the setup back to the injectors, im having the same popping sound in my setup,,,,, thanks let me know

 

i'm currently boosting 8psi, with no boost controller, i'm gonna install my avc-r soon so my turbo will spool faster, but plan on running 8psi still......the plugs don't look like they are detonating, but they do look a little lean

 

basically i drove the car for the first afternoon of it running with the stock b20 plugs......then i put in some bcpr6es-11's gapped at .030 and it took most of my popping problem away, but my car would hesitate before boost, while in boost, just basically the whole time, so i figured it was a fuel problem, and having replaced the fuel filter prior to my turbo install, and having the fmu that i know is good and my walbro pump, i figured it was the injectors.....and beeing that they came off a friends wrecked 92 si that sat for years with bad gas, then he fixed the car and tried to drive it i figured that was the problem, and it was.....
