I recomend the Go 5 port turbo with either the Go 0801 pipe or the dynamite 086. Power is similar I belive if broken in properly a Go will outrun a v-spec, my PTM 5 port in truggy was never pulled on the straight even against High end .28's. And you can get the motor and the pipe and still have $50 left over compared to the stock V-spec. And I belive you will have more longevity out of the Go also if broken in poperly.
