Rebuilding a 3.0l SC as a turbo

I’m looking for advice on a few 10,000-foot decisions with my 3.0l SC turbo rebuild. I’m not looking to find a core from a 3.2 or 930. I think the hp goals should be reasonable for my 3.0SC core.

Goal: <=450 WHP. Be able to run full power on the street but be able to turn the power down below 400 for track days. I only do about 3 or 4 per year.

I currently have:
• 3.2 Carrera Manifold
• Garrett GT030R Turbo
• Megasquirt II

Planned changes:

P&C:
• Mahle 98mm 7.5:1 P&C set – ($4500)

Rods:
• Carrillo Rods

Cams:
• Regrind SC cams to 964 profile

Heads:
• Upgrade valve springs, retainers, and guides.
• Twin plug
• Port match (within reason) to the Carrera manifold.

Additional planned updates:
• 964 Oil Pump.
• Upgrade case oil squirters
• ARP head studs.
• Refurbish the crank (machine out the oil plugs to truly clean it.)
• Upgrade intercooler
• MS3 Pro for full ignition control.
• Add knock control (I think MS3 can only handle 1 knock sensor input)
• 930 4-speed w/ LSD (Stock gearing, planning to drop 3rd and 4th down for better drivability on track)
