What size should I measure my Spark plugs in my car...
I've heard that when runnin turbo you run them at .30
Is that true? If not, wats a good measurnment that I can put them at so they could turn the car on fine, and have the right enough spark when runnin boost?

 

It all depends on how strong your ignition is. The stronger it is the bigger gap you can run.

 

Yea,
Basically I've done the basics in turbo charging my 03 Coupe Civic,
I Just Swaped the Injectors, to RC 310cc, I have a T 25 turbo kit,
So I mean I think I should'nt run it too high of a gap... But I am stll trying to figure out wich is best cuz every time adjust them they feel different some better then others.... right now i have them set as .30

 

Start off with the stock gap and go a little bit up at a time. Don't just create your own starting point.

 

I think Stock Gap Is .43 or so...
Is that too big?

 

I can't just say yes or no. I know of a few stock cars that use a .43 Why are you changing your gap anyway? Are you having problems fouling plugs, them not sparking enough, or what? I would try putting the plugs around stock gap first and then going from there. There are many indications of color and the look of a plug to determine what is happening. For example, Too hot would result in a white electrode cause by too lean or the gap off. Detonatin = cracked or chipped insulator. Usually caused by too much heat and not enough fuel ( You will hear a crushed aluminum can sound as well as some pinging) If the stock gap seems to work fine, then leave it. I also recommend you putting ngk v power or some sort of copper plug in, it ignites a lot better than platinum on a turbo car.
