Best internals and turbo for my 420a build?

[TypeONegative]

Hi finally got the 420a car running like new thanks to user chrysler kid, car idles like a dream and getting better mugs than my spyder, anyways so last week I bought a 420a engine to build, I want to build it for a turbo setup then swap it with my current engine, saving the current engine in the car for if/when the turbo setup fails or I just want to make it stock again, what am I going to need? I want to make at least more than a stock gst and want to start ordering parts for it I'm going to put it on the engine stand soon, any suggestions are gladly appreciated, also do I need to modify my transmission?

Eagle rods. Wiseco or JE Pistons. Other than that just freshen up everything else. You can get aftermarket cams but not really needed. The rods are the weak point in a stock 420a.

Trans will be fine but you will need to upgrade the clutch. I have only used south bend clutch. Loved both of them so never had a reason to try anything else out.
