> see that was what i was org. thinking that a bigger turbo on lower boost would produce more hp than a much smaller turbo maxed out… idk to much but thats what i thought

its all about volumetric efficiency and CFM. luckily youve got an AEB head already… a k03 is not efficient at higher boost levels, they just make loads of torque, and lots of hot air.
