2.4L 6bolt G4CS is probably the best way to go. GT35R, FP3065 or similar turbo will be perfect for that setup and your goals, Daniel J.
I think diff coolers are a bit excessive but touche’. You might also want to think about a dry sump oiler as well.
If you want any/all of my head parts, I will save them for you, big cams, ss valves (stock size), dual springs, ti retainers; good for a 10k valvetrain.
