I just noticed another piece you will need AB, the elbow the bolts to the standard inlet manifold.
There are 2 different versions of the elbow, the one shown below is the most common and has the over boost pressure relief valve on it, the other version has this blanked off. It's easy enough to remove the PRV and replace it with a threaded blanking plug. The PRV is set to vent over about 14Psi.
