Hello guys,
I have a B16A forged bottom end using Wossner 12.5:1 high compression Pistons and a B16B head (standard but flowed). I must admit I don't know the actual assembled compression but everything's down to the bare bones to try and get it as high as possible. Engine uses throttle bodies with ASNU 440cc injectors and a 2.5" equal length 4-2-1 straight through. Engine is fitted to a rally car.
My questions were, what spark plugs do people usually opt for for this kind of spec? I was tempted to stick some average NGK's in to get it started and to do part first of the mapping - then move onto race plugs for the final parts of the mapping.
Another thing was engine oil. Considering spec and application, what do people recommend?
Thanks in advance.
John
