If you want a brand new turbo then its goin to cost a lot more. You can get a turbonetics t3 super 60 which would probably work well for around $700 brand new. If your talking about a kit, for the whole thing your probably looking around $2400 give or take a hundred or so everything being brand new. If you havnt already got one, you will want to probably get a new clutch to handle the extra torque and then guages (id say maybe 2) and a boost controller if you want one. Then you just have to add in labor if you dont do the work yourself.

hope that helps and i didnt ramble on about stuff you already know
