You will need the 440cc injectors, high-flow fuel pump and a 1:1 riging rate regulator to be able to go the stage3 boost route. Check it out on the bottom of this page
http://www.hondata.com/boost.html or are the above components included? If so, I might consider doing it that route. To go the Stage4 route, you will need in addition to the parts above, the Motec Lambda Meter. Then you can tune without the dyno
It is only another 1300 bucks!
