What sprk plugs should I use in my turbo 1914. I am using a blowthrough system with intercooler. My plugs foul alot!

Sounds like you are running too rich, especially on the idle jet, as this is what causes most fouling(rich at idle).
If you have no temp issues go two steps up in plug heat range(NGK = two #'s lower) from where you are now and try that. Also check your fuel pressure.

I like Denso Irridium IW24's.
Work well for me.

What plugs are you using now?
What CR are you running?
One carb or two?(What breed of carb/s)?
or Fuel inj?
If carb or carbs-what jetting?(particularly idle circuit?)
What heads are you running? (1/2" or 3/4" reach plugs?) What intake vs exhaust valve sizes?
