get a tbe,blitz sus or similar,and a boost controller. i prefer electric, but mbc's are good to. you shoudl see decent gains with that. get some coilovers or springs if your poor like me. it'll reduce understeer,and ditch that horrid front fender gap. i have a hks bov as well, but i got it for like 50 bucks. i really like it, my car runs fine.
