from the research i've done on several diff kits (greddy, full-race, drag, revhard, turbonetics) i've decided on the greddy kit for several reasons

-makes good midrange power (not 400whp like full-race)
-no need to modify internals unless ur building up a lot
-reliable
-good chance for upgrades but dont need to
-legal in CA (where i live)

so if thats what you were going for....the greddy kit should suit you just fine
