I would say cam, intercooler,headers, CAI/FWI, u-bend delete, rockers, 180tstat, colder plugs w better wires, good tune... thats a good set up for a pretty small pulley... I wouldnt go that low on your DD... you could get by with less... wouldnt reccomend it but it could be done... thrashercharged.com sales a package deal w a few mods...
