Like Joseph said, if you plan on using the stock manifold, the turbo will need to have a 5 bolt turbine housing (for external wastegate) or have an internal wastegate. What size turbine is it? .63, .82? -modify the oil lines. If it was the ball bearing GT30R then you would also need to modify water lines. -modify the downpipe connection/possible dump tube integration -tuning -machine manifold flange
