I have a Weapon R Hyper that has been great. All you need to add to it is an oil catch can ($40 from Jeggs).
I have heard RalliSpec is the best of the best of the best. They have neet stuff that comes with theirs. Things like the oil catch can and a heat sheild/baffle. Oh for the RS it comes with a hood vent spacer to open up the one hood vent and force a little more air in there.
