318 rebuild for turbocharging

I know this is old but I'm bringing it back because my 360 recently took a dump (broke a piston, cracked cylinder) and it looks like I'll be building this 318 sooner than later.

I am on a budget but I'm willing to spend extra money on necessary good parts. So how necessary are forged pistons, aftermarket rods and crank? The Magnums I pulled off the 360 look good, I will have them gone through by a machine shop and if they are still good I'm going to swap them over to the 318. I also have the Air-Gap manifold and carb I can swap over so I can run the engine N/A initially while I save up more for all the turbo parts.

I am a bit leary of running cast/hyper pistons again because those are what broke in my 360 however I was pinging the crap out of it on a regular basis; had quite high cylinder pressure (10.5:1 and 256/262 adv. duration cam) so I know if I re-do it things will be done differently. For starters I'm definitely building for 9-9.5:1 MAX static comp...
