Ok, so pardon my ignorance (believe me, I've got a LOT of questions), but why exactly should I swap my 1zz for a 2zz? I figure, my 1zz is lighter and has a shorter stroke (leaving more room in the cylinder for fuel and air thus more potential power). On top of that, i just dont feel like (and cant really afford) dropping $1200-3000 on a 2zz. Am I right? Or can someone show me the error in my ways?
