get a painless wiring TPI harness, a TPI computer. Either go with a modified LT1 intake or a TPIS mini ram intake. Have to run a fuel setup for it as well and get all the sensors and injectors and what not

If you wanted to go the cheaper route, you could use an old TPI intake setup and just home port it. But it will be a big bottle neck when you do install the prorcharger.
