Hey if you have a built bottom end then you can make a lot of power but then again you didn't tell us what bore you are going to run, if your head is ported or not, what intake manifold you are going to run, what cams, what turbo, what exhaust manifold, what fuel management system, what size injectors, are you going to get springs and retainers, what size intercooler, BOV, LIQUID TO AIR COOLED OR AIR INTER COOLED, or even what waste gate? If you can answer theses questions then we can give you a better answer sir.
