Once you've chosen your turbo, IC and twin plug, there are only two things you can manage to reduce detonation: timing and fuel. In my opinion, adding fuel to cool the charge to reduce detonation only works to a certain point. I've seen motors run at a very low AFR that successfully eliminates detonation only to wash the cylinders of oil and severely accelerate cylinder/ring wear (as well as dilute the engine's oil supply) and trash your valves. Being able to properly tune a modified, air-cooled, 30 year old turbo motor is kind of an art. For my motor, my lowest AFR is 11.8 and timing at .8 bar, 6000 rpm is 18 degrees.
