On a serious note I would boost it...I am not a big fan of VTEC due to the fact that I am not familiar with it (don't understand the purpose there for I find it useless) . I am used to a single cam with a set size in a motor that is a little bit bigger than a 4 cyl. I am also not a scholar on the facts of different motors...I mainly know a little about the b series. I would boost it just because its the easiest way to pull more power out of small displacement motors.
