What is a good a/f ratio for turbo sohc?
set up
-sohc d15b7,y7 head
-cr 10.1:1
-7psi non-intercooled
-fmu
-255 fuel pump
My a/f ratio is in the 14's at all rpm. I have detonation at full boost. I know i need a intercooler, but do I need a lower fuel ratio to get cure the detonation?

14.x:1 is WAY lean...
12.8:1 is about as lean as you want to run any turbocharged street car...and the closer to 12:1 you get, the safer it is...generally speaking, of course every car responds differently.
What size injectors are you running? And what fuel pressure @ 7psi of boost?
