If you plan on running nitrous as well, I'd get a Walbro fuel pump, maybe some larger injectors, a fuel pressure regulator, and also a high performance clutch..... like an act.
Oh wait, you have an auto, so I would recommend the Level 10 shift kit.. hopefully your tranny will be able to handle all that power.. don't forget a tranny cooler, and a regular oil cooler wouldnt hurt either..
