turbocharging '89 SHO needs help!!! (sorry its not mstng related)

[8ur-vet]

My goal is to achieve 330 hp from my SHO and to do this I need 9 psi of boost. For my turbos I would use 1 or 2 rebuilt turbos from the late 80's dodge cars.I realize some fabrication would be needed. I would also make use of the MSD 6btm ignition to controll timing when the boost increases. Im just wondering about the air/fuel mixture and how I would go about adjusting and controlling that all oof your info is greatly apprecieated. Thanks.
