Well as far as the clutch you will need a 01-04 clutch setup and lockup if you intend on drag racing it PC i dont know, Boost controller AMS1000 is the best, boost by smith has a gear based setup that works great too.
I know first hand on the turbo setup for the 05-06 1000 i built a kit for my friend and he has beat on it all year (he has ran7-8lb on a stock motor) with no problems at all except the stock clutch setup wont hold,we dont use a pc we use secondary inj. for the fueling so it drives like a stocker till it boost's. I also helped a guy on gixer.com setup his secondary system on his 04 1000 and it ran great too.
