k, first thing I've been working with my supercharged t-bird for a few years now so i can give you some insight into this.
if you've got a sock comp. ratio of less than 8.0-1
you should be good so far.
rods are going to be the weak link in most boosted applications above about 10LBS.
injector size should go up along with a FMU/boost sensitive fuel pressure regulator. every pound of boost you add to the intake the fuel pressure needs to go up equally to compensate for the increased resistance the fuel encounters.
cams; as close to ZERO valve overlap as possible. you don't want to bleed off your pressurized air into the exhaust system. raise your exhaust duration/lift to get the extra gasses out.
remove restrictions from the exhaust system. free flowing cats and mufflers and mandrel bends in the pipes.
heat management is key also after about 6LBS of boost. an intercooler/after cooler should be used above 8 LBS and is a necessity after 10 LBS. the heat can be immense in high boost applications. I've seen as much as 300 degree outlet temps before my intercooler! water to air works the best and can be packaged pretty small. air to air with fan is next best.
timing, get a boost retard system. possibly one with a boost line fitting. it'll back out timing to start the firing event earlier to ensure you get all out of your air charge w/o detonation.
lastly plugs, 1 to 2 steps cooler or decreased gap to prevent spark blow-out. hotter coil never hurts too.
