Then there is the question can I do it myself and not have the Z for a month or more, or do I spend more and have it professionally done in a few weeks.

I don't know what your budget is but seeing that the AT already puts an upper limit on power/torque an SC kit would probably make more sense. Things that you really should get on top of what ever FI you go with are a oil catch can, gauges (oil pressure, boost, AFR). Also don't forget about all the fluids and extra wires, hoses, cables, connectors you'll need will add up. Also probably best to do engine and trans mounts. And then probably a proper diff and diff mount.

Also keep your front crash bar because **** happens.
