I had been looking at the kit from Andy's Autosport (http://www.andysautosport.com/honda/...b00091771.html) but I actually found a better one somewhere. I'll go back and try to find that link... when I do I'll post it.
Andy's doesn't tell you what all is included in the kit online... I had to call them. They're kit doesn't come with a boost controller or engine management unit, so those two things plus the exhaust would need to be bought for that kit.
Basically here's what you'll need altogether:
-Turbo
-Downpipe
-Free-flowing cat
-Larger exhaust
-Turbo manifold/turbo header
-Wastegate
-Blow-off valve
-Boost controller
-Piping and clamps
-Intercooler (not necessary, but it does increase HP by cooling the intake charge... you can add this later if you want)
-Some form of engine management or fuel & ignition controller
-Injectors (usually 440cc is more than enough... and they're usually included)
-High-volume fuel pump (not always required... depends on your kit and boost psi)
-Colder plugs
-Helps to have a high-capacity spark discharge system, but not necessary.
-Turbo MAP sensor
I think that's everything... You really don't need a new intake (as is often the myth) nor do you need to o-ring the head (unless you really get crazy with the boost).
