Phillk20

So I am planning on starting a k series build around the end of this year. I was originally just going to do a full k20a2 engine build but I've got to thinking. I was to fully build this motor top to bottom to where nothing what so ever can be done to squeeze more power. I want your guy's opinions on motor options and how you think I should go about the build. Keep in mind that I do want to run boost NOT all motor
