Disconnect the intake and exhaust plumbing from the turbo housing, then carefully loosen the mounting bolts and remove the turbo from the exhaust manifold. Place the turbo assembly in a vise. It's necessary to separate the exhaust portion of the assembly, so scribe a mark between the two pieces to ensure the new Banks piece can be positioned the same way on the turbo. Unbolt the wastegate assembly per the instructions, loosen the bolts connecting the two pieces, and carefully separate them. It may be necessary to lightly tap the connection to persuade the parts to separate, and be sure to remove any residual rust before installing the new turbine housing.
