Remember there's a combination of elements that makes a fast car, if you're driving a Zed, 90% of other people you will beat with the vehicle motionless (and the right stance). It's not about power unless you plan to do some track work, but then again if you come from that 2JZ world stick with it. I must be one of only a few guys who's put a Cleveland in a Zed, LS1 and RB conversions are popular. I admire someone who takes the path least travelled.
